[MRI in spondylitis and spondylodiscitis].

Magnetic resonance imaging (MRI) is highly sensitive and specific for the diagnosis of spondylitis and in that respect is superior to other radiologic methods. Its excellent morphological resolution allows early recognition of pathologies and spread of the spondylitis. Affected vertebral bodies and discs reveal typical alterations in T1- and T2-weighted images; post-gadolinium images are necessary to improve specificity. MRI helps to diagnose tumors and degenerative changes. Thus, MRI is the method of first choice in the diagnosis and surveillance of spondylitis and spondylodiscitis.

The value of MRI in the diagnosis of postoperative spondylodiscitis.

We evaluated the role of MRI in the diagnosis of postoperative spondylodiscitis. Spondylodiscitis is a serious complication of surgery, and the diagnosis frequently depends on a combination of clinical, laboratory and imaging findings. We compared the MRI findings in six patients with biopsy- or surgery-proven spondylodiscitis with those in 38 asymptomatic postoperative patients. Contrast enhancement and signal changes in the intervertebral disc or the vertebral endplates are not specific for spondylodiscitis, being also seen in the asymptomatic patients. However, absence of Modic type 1 changes, of contrast enhancement of the disc or of enhancing paravertebral soft tissues suggests that the patient does not have spondylodiscitis. MRI appears more useful for exclusion than for confirmation of postoperative spondylodiscitis.

Symptomatic intraspinal synovial cysts of the lumbar spine: correlation of MR and surgical findings.

The purpose of the study was to determine the frequency of associated MR imaging findings in patients with symptomatic lumbar intraspinal synovial cysts, and to correlate MR with surgical findings. MR imaging studies of 18 patients with surgically and histopathologically proven lumbar intraspinal synovial cysts were retrospectively analyzed and correlated with surgical findings. The diameters of the synovial cysts ranged from 10 mm to 28 mm, with a mean of 16 mm. A nonhemorrhagic cyst was found in 15 patients (83%), and a hemorrhagic cyst in three patients (17%). Degenerative spondylolisthesis was found in six patients (33%) at the level of the synovial cyst, with displacement ranging from 3 to 5 mm, mean 4 mm. Surgery revealed instability and hypermobility of the facet joint at the level of the synovial cyst in all patients with degenerative spondylolisthesis, and in five additional patients. Symptomatic synovial cysts of the lumbar spine were associated with degenerative spondylolisthesis in six of 18 patients (33%) and with instability of the facet joint in 11 (61%). These findings may support the theory that increased segmental motion plays a role in the pathogenesis of synovial cysts.

MRI demonstration of cervical spondylodiscitis and distal full-length bilateral paraspinal cold abscesses successfully treated by drug regimen only.

OBJECTIVE: Cold abscesses, although common in spinal tuberculosis, are usually localized to the level of infection, follow tissue planes, and may extend into the spinal canal at any level. They may cause symptoms resulting from neurovascular compression, hemorrhage, and direct mass effect. DESIGN AND PATIENTS: We present an unusual case of cervical tuberculous spondylodiscitis in a 25-year old man with a cold abscesses involving the retropharyngeal, mediastinal, and retroperitoneal areas bilaterally. The abscess tracked from the neck to the psoas muscles bilaterally. Following the diagnosis the patient received 9 months of antituberculous therapy. RESULTS: MRI showed resolution on medical treatment alone. CONCLUSIONS: Even in the presence of massive paravertebral cold abscesses medical treatment alone may well suffice for this common worldwide disorder. MRI is ideal for monitoring regression of massive abscesses in deep anatomical locations.

Lumbar false aneurysms following image-guided interventive procedures for spondylodiskitic abscesses.

Pseudoaneurysms of the lumbar arteries are infrequent, and are most often found incidentally after trauma to the lumbar spine. More rarely, they are an iatrogenic complication from diagnostic or therapeutic procedures, particularly of the kidney. Their rupture can cause rapid clinical deterioration by retroperitoneal hemorrhage, and therefore their diagnosis and treatment must be rapid. We report two cases of lumbar artery false aneurysms arising as a complication during the treatment of infectious disciitis. The diagnoses were established via CT and immediately followed by expeditious treatment by selective arterial embolization.

Recurrent acute low back pain secondary to lumbar epidural calcification.

INTRODUCTION: Epidural calcification is a rare cause of back pain, and spontaneous epidural calcification has not been reported previously. CASE REPORT: We describe a patient with acute low back pain and signs of lumbar nerve root compression due to epidural calcification, as demonstrated by CT-scan and MRI. Radiological signs of spondylodiscitis led to a search for an infectious cause, which was negative, and her symptoms responded rapidly to NSAID treatment alone. Her symptoms recurred 18 months later, and further imaging studies again revealed epidural calcification, but with a changed distribution. Her symptoms were relieved once more by NSAID treatment alone. DISCUSSION: We propose that epidural calcification secondary to aseptic spondylodiscitis is the main cause of acute back pain in this patient. A possible mechanism may be the pro-inflammatory effects of calcium pyrophosphate or hydroxyapatite crystal deposition within the epidural space.

Intramedullary spinal cord abscess complicating thoracic spondylodiscitis caused by Bacteroides fragilis.

Intramedullary spinal cord abscess associated with infectious spondylodiscitis is a rare entity. The case of a 66-year-old man with an intramedullary spinal cord abscess complicating thoracic spondylodiscitis is presented. The patient was unable to ambulate independently due to weakness of the legs. MR imaging showed findings suggestive of infectious spondylodiscitis at the T5-T6 level associated with epidural and intramedullary spinal cord abscesses. Biopsy of the intervertebral disc was performed and Bacteroides fragilis was isolated. Antibiotic therapy was instituted, and MR imaging of the thoracic spine was performed 6 weeks after the initiation of treatment, showing resolution of the epidural and intramedullary spinal cord abscesses.

Clinical validation of the avidin/indium-111 biotin approach for imaging infection/inflammation in orthopaedic patients.

We report here the results of a validation study of the avidin/indium-111 biotin approach in patients with skeletal lesions. This study involved 54 patients with orthopaedic conditions: 20 patients with intermediate suspected osteomyelitis of the trunk, 19 patients with infection/inflammation of prosthetic joint replacements, and 15 patients with suspected osteomyelitis of appendicular bones. Avidin (3 mg) was injected as an i.v. bolus, followed 4 h later by 111In-biotin; imaging was acquired 30 min and 16-18 h after administration of 111In-biotin. Technetium-99m hexamethylpropylene amine oxime (99mTc-HMPAO)-labelled leucocyte scintigraphy was performed in 39/54 patients. The overall sensitivity of the avidin/111In-biotin scan was 97.7% (versus 88.9% for 99mTc-HMPAO leucocyte scintigraphy). While the diagnostic performance of avidin/111In-biotin scintigraphy was similar to that of 99mTc-HMPAO leucocyte scintigraphy in patients with prosthetic joint replacements or osteomyelitis of appendicular bones, the avidin/111In-biotin approach clearly performed better than 99mTc-HMPAO leucocyte scintigraphy in patients with suspected osteomyelitis of the trunk (100% sensitivity, specificity and accuracy versus 50% sensitivity, 100% specificity and 66.7% accuracy for 99mTc-HMPAO-leucocyte scintigraphy). These results demonstrate the feasibility of the avidin/111In-biotin approach for imaging sites of infection/inflammation in the clinical setting. Although no systematic advantages of avidin/111In-biotin scintigraphy were found versus 99mTc-HMPAO leucocyte scintigraphy, the newer scintigraphic method is more practicable and involves lower biological risk for the operators.

Brucellosis of the spine: evaluation of the clinical, laboratory, and radiological findings of 14 patients.

In this study, we aimed to assess the clinical, laboratory and radiological findings of vertebral involvement in brucellosis. Fourteen patients diagnosed with spondylitis and spondylodiscitis due to brucellosis were included in the study. Computed tomography, magnetic resonance imaging, or scintigraphy were used to diagnose the vertebral involvement. The control group consisted of 20 patients with brucellosis but no vertebral involvement. The clinical, laboratory, and radiological findings of both groups were compared. The prevalence of vertebra involvement in brucellosis was found to be 7.5%. Of the 14 study patients, two had thoracic, ten had lumbar, and two had both lumbar and sacral vertebral involvement. The associated pathologies were spondylodiscitis, narrowing in the intervertebral space, inflammation or abscess formation in the paravertebral soft tissue, and osteophyte formation. None of the patients had a collapsed vertebral body, angulation deformity, or inflammation in the epidural space. In conclusion, the possibility of vertebral involvement should be remembered in chronic brucellosis, particularly in elderly patients who present with back pain or tenderness over the spine. A high index of suspicion and clinical, laboratory, and radiological examinations help confirm the diagnosis of vertebral involvement.

Could remembering the prozone phenomenon shorten our diagnostic journey in brucellosis? A case of Brucella spondylodiscitis.

We reviewed a case of Brucella spondylodiscitis admitted to a referral, university hospital, in Ankara, Turkey. A 75-year-old female was referred to our hospital with low back pain. Previous magnetic resonance imaging yielded cortical destruction of T9-10 and T12-L2 vertebral bodies, focal infectious foci at discs within this range, significant microabscesses at paravertebral areas, which lead to the diagnosis of spondylodiscitis. History of consumption of unpasteurized dairy products led us to first suspect brucellosis yet, the serum agglutination test and blood culture were negative and did mislead us to several other, sometimes invasive, diagnostic tests. The final diagnosis was reached by culturing the specimen obtained through fine-needle aspiration from the paravertebral microabscesses. The exhausting diagnostic journey that started with the suspicion of tuberculosis or malignancy ended with a diagnosis of brucellosis. Brucellosis should be considered in all patients with osteoarthritic complaints in endemic regions, and the "prozone phenomenon" should be kept in mind, before proceeding to high-tech lab tests, imaging, or invasive procedures.

Contrast-enhanced MR imaging with fat suppression in adult-onset septic spondylodiscitis.

Spinal infections typically involve vertebrae as well as discs, and for this reason they are called septic spondylodiscitis. Magnetic resonance imaging is the most sensitive imaging method for the evaluation of this group of spinal diseases. The use of contrast-enhanced T1-weighted sequences with fat suppression, if correctly applied, may increase information provided by MRI. Firstly, this technique allows the primary vertebral focus, which often precedes disc involvement, to be identified at a very early stage. When the disease spreads, T1-weighted fat-suppressed gadolinium dimeglumine (Gd-DTPA) enhanced images provide macroscopic details of the primary vertebral focus, disc involvement patterns, and pathways of infection diffusion. All this information, when correlated with laboratory tests, may be useful in identifying the infectious agents (tuberculous vs piogenic forms), thus enabling a suitable therapy to be started. This technique is also useful in the assessment of the real extension of the disease, providing a clear depiction of paravertebral space involvement and of psoas muscle abscesses. Dangerous complications, such as meningitis, myelitis, and epidural abscesses, may be more promptly diagnosed and fully evaluated with fat-suppressed post-contrast T1-weighted images. Finally, this imaging technique may help to differentiate infectious processes from degenerative disorders, extradural neoplastic processes, and rheumatic diseases.

[Erosive intervertebral joint lesions. A case of pigmented villonodular synovitis].

Pigmented villonodular synovitis (PVNS) is a rare proliferative lesion that can affect synovial membranes, tendon sheaths, and bursae. It is usually a monarticular disease of the lower extremities, and so far fewer than 30 cases of spinal involvement have been reported in the literature. We describe a patient with progressive lumbar pain and spinal claudication, in whom a CT scan of the lumbar spine revealed destruction fo facet joints L3 to L5. An open biopsy was performed, which led to the diagnosis fo PVNS. The patient underwent successful surgical resection of the tumour mass and stabilization of segments L3 to S1. Two years after surgery the patient has no signs of recurrence. Differential diagnosis of erosive vertebral joint disease is discussed.

[Possibilities and limits of conservative therapy of spondylitis and spondylodiscitis].

BACKGROUND AND AIM OF THE STUDY: For many years the treatment of spondylitis and spondylodiscitis has been discussed controversially. The aim of this study is to report on objective and subjective mid-term results of therapy of spondylitis and to present a differentiated concept of treatment. METHODS: Between 1988 and 1996, 58 patients were treated with spondylitis or spondylodiscitis. Nine of these patients had to be operated. A biopsy was taken in all of the cases. According to the antibiogram obtained by the biopsy, antibiotics were applied intravenously. The patients were immobilized by a plaster bed for at least 6 weeks and were then treated by a spinal orthosis for another 3 months. Patients were re-examined clinically and radiographically and by a questionnaire (including Roland-Morris score), after 8 years on average. RESULTS: Patients were diagnosed correctly 4 months after the begin of the disease. Spondylitis was predominantly localized in the lumbar spine. A positive bacteriological culture was derived from one third of the biopsies; none of them was a specific culture. C-reactive protein was revealed as appropriate for diagnosis and follow-up of spondylitis. In 84% of the patients a total or partial bony fusion was demonstrated radiographically. Questionnaire assessment revealed a significant decrease of the Roland-Morris score (17.8-7.4) and a significant relief of pain (8.9-2.5). CONCLUSIONS: We recommend surgical treatment on patients with major vertebral body destruction, epidural abscess and progressive neurological impairment. These indications for operation can be prevented by a rapid diagnosis, so that spondylitis can be successfully treated by consequent immobilization in a plaster bed and appropriate antibiotics.

One case of gram-negative anaerobic spondylodiscitis with Prevotella intermedia.

We report the case of a 45-year-old woman with spondylodiscitis at L1/L2, communicating with paravertebral, intravertebral and bilateral psoas abscesses. Percutaneous computed tomography (CT)-guided abscess drainage and an intravenous antibiotic therapy with Imipenem were performed. After removing the drainage at 2 weeks, the patient was discharged at 4 weeks with normalized blood parameters, normal temperature, and without need for analgesics. The underlying bacterium in the case was a very rare gram-negative anaerobic bacterium: Prevotella intermedia.

Surgical treatment with spinal instrumentation for pyogenic spondylodiscitis due to methicillin-resistant Staphylococcus aureus (MRSA): a report of five cases.

INTRODUCTION: The treatment of methicillin-resistant Staphylococcus aureus (MRSA) spondylodiscitis is reported to be far more difficult than that of non-MRSA spondylodiscitis. At present, there seems to be no standard protocol for the treatment of MRSA spondylodiscitis cases in which conservative management has failed. MATERIALS AND METHODS: Between 1998 and 2001, five patients (aged 48-73 years; average: 63.8 years; SD: 9.9) with MRSA spondylodiscitis were treated surgically after conservative treatment had failed. Posterior spinal instrumentation was performed for all five patients, three of whom also underwent anterior debridement and bone graft. All the patients had neurological deficits and severe pain. To assess the invasiveness of the operation, we evaluated operating time, blood loss, and complications. Pain (verbal rating scale; VRS), neurological status (Frankel type), activities of daily living (ADL) (the Barthel index), WBC, CRP, and ESR in the preoperative, postoperative and final follow-up periods were used to evaluate the surgical outcomes. RESULTS: Although we encountered several postoperative complications including deep wound infections, at the final follow-up visit, the neurological deficits, activities of daily living, Barthel index, and VRS had improved in all the patients. Changes in WBC, CRP, and ESR revealed suppression of infection in all patients. CONCLUSION: Surgical treatment for MRSA spondylodiscitis with posterior spinal instrumentation provided patients with satisfactory final outcomes.

Anterior versus posterior plating in cervical corpectomy.

This is a prospective study comparing anterior and posterior plating in cervical corpectomy. Each group comprised 30 patients who were candidates for corpectomy. In the first group, anterior plating was done using Orosco-type titanium plates. In the second group, lateral mass plating was done. In all cases, titanium cages were used to replace the removed vertebral body or bodies. The mean follow-up was 12.68 months (SD 3.85 months). Pseudarthrosis was not encountered in either group. Posterior plating was better than anterior plating in terms of the stability of the construct and problems related to the hardware. Screw breakage was encountered in seven patients with anterior plating (23.33%). This complication was not seen in the group with posterior plating. The difference between the groups was statistically significant (chi-square = 7.92, p = 0.004). Screw loosening was encountered in 2 patients in the group with anterior plating and in only 1 patient in the group with posterior plating. The difference between the incidence of screw loosening in both groups was not statistically significant (chi-square = 0.35, p = 0.5). Sinking-in of the cage was encountered in 7 cases with anterior plating and in only 3 cases with posterior plating. However, the difference between the groups was not statistically significant (chi-square = 1.92, p = 0.16).

Diagnostic and therapeutic management of lumbar and thoracic spondylodiscitis--an evaluation of 59 cases.

Fifty-nine patients with spondylodiscitis (SD) of the thoracic and/or lumbar spine were followed-up clinically and radiologically [X-ray, computed tomography (CT), magnetic resonance imaging (MRI)] over a mean time of 2.2 years (1-6.5 years). All patients without abscess formation (n = 35) were treated conservatively. Out of the group with abscess formation (n = 24) 6 patients were also treated conservatively, 11 were drained under CT control and 7 were operated. At time of diagnosis, "signs of florid inflammation" were seen in 60% of the roentgenograms, in 93% of the CTs and in all of the MRls. The sensitivity to differentiate between SD with and without abscess formation was 85% by MRI and 69% by CT. "Signs of regressive inflammation" and "signs of increasing osseous consolidation", essential facts for starting remobilization, could first be seen using CT 6 weeks after onset of therapy. Using MRI these signs were seen with a considerable delay at 12 weeks. Clinically, only 3 of the 59 analyzed patients developed recurrent SD. In conclusion, MRI is the radiological method of choice for establishing the diagnosis of SD, in particular with regard to differentiating between cases with and without abscess formations. In contrast, CT is superior for performing success control after treatment. Therapeutically, conservative, minimal-invasive and operative procedures are not rival but rather complementary.
