Back pain in children and adolescents.

Back pain in children is a common problem that is infrequently reported to physicians. Persistent back pain in children is serious, and most conditions can be diagnosed with relatively simple tests, including diagnostic plain radiographs and bone scans. Many cases, including strains and sprains, are relieved with rest and decreased activity. If persistent back pain, increasing pain, fever, or neurologic deficit is present, referral to the orthopedic surgeon should be swift until a specific cause can be found and treated.

Imaging of pyogenic infectious spondylodiskitis.

The presence of infectious spondylodiskitis and its complications may present protean clinical and imaging findings. The frequent use of multi-imaging modalities has led to a greater sensitivity and specificity in the diagnosis of this ubiquitous disease.

Imaging of musculoskeletal infections.

Imaging studies play a critical role in the diagnosis and management of musculoskeletal infections in children. Conventional radiography is usually the first imaging study performed with other imaging modalities as needed. Ultrasound is helpful in detecting joint effusions and fluid collections in the soft tissue and subperiosteal regions, and may guide localization for aspiration or drainage. CT can demonstrate osseous and soft tissue abnormalities and is ideal for detecting gas in soft tissues. Nuclear scintigraphy and MR imaging are valuable because of their high sensitivity. Scintigraphy is particularly useful in identifying multifocal involvement, which is an important consideration in neonatal osteomyelitis and CRMO. MR imaging provides accurate information on both the soft tissues and bones and is our imaging study of choice for evaluating the local extent of musculoskeletal infections.

Spondylodiscitis in patients with spinal cord compression: a possible pitfall in radiation oncology.

PURPOSE: In patients presented for spinal irradiation it may be difficult to distinguish between malignant and benign lesions if only plain X-rays and computed tomography (CT)-scans are available. Spinal magnetic resonance imaging (MRI) can be of great diagnostic value. METHODS: From 11/1995 to 05/2000 447 patients were presented for spinal irradiation, 264 beyond regular operating hours. At presentation no spinal MRI was available in 170/447 and 132/264 patients. RESULTS: After spinal MRI, diagnosis was changed from vertebral metastases to spondylodiscitis in 10/170 and 8/132 patients. Six of these patients were already known as cancer patients. CONCLUSION: In patients presented for spinal irradiation spondylodiscitis is not very uncommon. If there is any doubt about metastatic disease as the cause for spinal cord compression a spinal MRI has to be demanded, even beyond regular operating hours.

[Bone scintigraphy in two cases of primary vertebral osteosarcoma in adults].

The primary vertebral osteosarcoma in adults is a rare tumor which represents less than 2% of all osteosarcomas. We present the cases of two men (40 and 33 years old) who began with pain and neurological compression symptoms. The imaging methods used to study the tumors were X-rays, CT, MRI and bone scintigraphy with 99mTc-HMDP. After the pathological diagnosis, the tumors were removed surgically and the treatment was completed with chemotherapy and radiotherapy. In this report the authors review the published cases of vertebral osteosarcoma, its epidemiology, clinical presentation and characteristics in the different imaging techniques.

[Psoas abscess as cause of lumbar spine pain detected by scintigraphy with gallium in a patient with suspicion of spondylodiscitis].

A 56 year old man with fever and lumbar pain who underwent an abdominal CT scan that showed lumbar arthrosic changes, although it was not possible to rule out infectious disease in L5/S1. Bone scintigraphy was requested. It showed heterogeneous hyperuptake that did not make it possible to exclude a spondylodiscitis in this site. Scintigraphy with 67Ga-citrate excluded infectious diseases in the lumbar spine column. However, a pathological uptake was observed in the left iliac fossa suggestive of psoas abscess, which was confirmed by ultrasonography, isolating streptococcus viridans.

[Association of infectious aneurysm and microbial spondylodiscitis: physiopathological hypotheses, diagnostic and therapeutic approach].

Two years after a Staphylococcus aureus septicaemia, in a patient with dermatopolymyositis occurred an infectious aneurysm of abdominal aorta with contiguous pyogenic spondylodiscitis. Coexistence of both pathologies is rare and physiopathological mechanisms still remain uncertain. However, many arguments in the present case report are in favour of the initial responsibility of an infectious aneurysm. Main interest in early diagnosing infectious aneurysm, allowed by new investigations such as magnetic resonance imaging and marked leukocyte bone scanning, is the prevention of major complications. Antibiotherapy and surgical removal of infectious aneurysm must be quickly achieved in every case.

[Candida spondylodiscitis. Report of 2 personal cases and 28 cases from the literature].

Vertebral osteomyelitis caused by Candida spp. has recently been described and seems to be rare since only 30 cases have been published so far. Its clinical, laboratory and radiological features are identical with those on non-tuberculous bacterial spondylitis. It develops in subjects with poor general condition who underwent multiple surgical operations or received prolonged antibiotic therapy. The finding of Candida at needle biopsy of the since clinches the diagnosis. Serological tests might provide an earlier diagnosis and, above all, enable therapeutic effectiveness to be evaluated. In 27 of the 30 cases reported here, cure was obtained by prolonged infusions of antifungal drugs, chiefly amphotericin B and/or 5-fluorocytosine.

[Aneurysm of the thoracic aorta and spondylodiscitis disclosing brucellosis].

Brucellosis, which decreased during the eighties in France, remains a public health problem in many Mediterranean countries. We report the case of a 65-year old patient native of Morocco, of thoracic aorta aneurysm and lumbar spondylodiscitis due to Brucella melitensis, revealed by haemoptysis and lumbar pains, with a favourable outcome after aortic graft resection, spinal plaster immobilization and specific lengthy antibiotic treatment. This case report is characterized by the absence of endocarditis or infectious focus near the aneurysm. Diagnosis of aneurysm and spondilitis due to Brucella melitensis is based on imaging and bacteriological and serological examination. Because of a clinical and biological intolerance for rifampicin and cotrimoxazole, this patient received ofloxacin-doxycyclin-streptomycin. We discuss antibiotic recommendations and stress the interest of the early diagnosis of complicated forms of brucellosis for a better prognosis.
