[Diagnostic problems apropos of 2 clinical cases of lumbar Pott's disease].

Two cases of POTT's disease without radiological osteoarticular destructions have been diagnosed from a psoas and a dorsal abscess. Bacteriology and histology were negative at the beginning, then became positive after a long evolution of the wound. The recommendation is to think of POTT's disease when confronted with any paravertebral abscess, with or without radiological signs and to repeat the bacteriological and histological tests if necessary.

[Anaerobic deep abscesses with unusual location: report of 5 cases].

OBJECTIVE: Anaerobic deep abscesses are rare and may have unusual location leading to severe outcome due to delayed diagnosis and treatment. In order to improve their diagnosis, we report and analyse 5 new cases. METHODS: Patients were seen from 1999 to 2003 in a single department of internal medicine of the university hospital of Marseille. RESULTS: Five new cases were diagnosed consisting in 3 females and 2 males with a medium age of 56,8 years, with unusual location in 4 cases: epidural (2), psoas (1) and sub-diaphragmatic (1) or circumstances in one case of pulmonary abscess unrelated to inhalation. Predisposing conditions thought to compromise resistance to infection were found in all cases: social poverty (4/5), alcoholism (3/5), smoking (4/5), teeth and periodontal disease (4/5), neoplasia (2/5), iatrogenic disease (2/5). Symptoms were insidious (5/5) and unspecific but were always related to the abscess location. Abscesses were frequently found distant from the initial focus of infection because of frequent hematogenous spread (4/5). Drainage of the collection led to bacterial identification in all cases (4/4), although blood cultures could be positive (3/5) and helpful in one case in which drainage was not possible (1/5). The isolated organisms always corresponded to the suspected initial focus (oropharynx 4/5 and digestive 1/5). Finally, combination of surgical drainage and double prolonged antibiotherapy (penicillin+metronidazole) was the elected treatment. CONCLUSION: Since hematogenous diffusion is frequent, anaerobic infection should be suspected in any case of deep abscess affecting patients with predisposing conditions such as poverty, severe teeth disease or iatrogenic procedure.

Ruptured abdominal aortic aneurysm secondary to tuberculous spondylitis.

A 69-year-old man was admitted with low back pain and signs of nerve root compression. A computed tomography (CT) scan showed abscess formation in the left psoas region, spondylodiscitis L3-L4 and a ruptured abdominal aortic aneurysm. The aortic aneurysm was replaced with a bifurcated vascular graft. One week later, laminectomy at the L4-level was done. In a small abscess, Mycobacterium bovis was found. The condition was considered to be a mycobacterial spondylitis secondary to BCG instillations of the urinary bladder for carcinoma. The patient received antituberculous medication for 9 months. Subsequently bone transplantation and internal fixation of the spine became necessary. Three years after surgery he is in good condition and there are no signs of graft infection on CT. Spondylitis and mycotic aortic aneurysm should be kept in mind in patients who have been treated for carcinoma of the bladder with BCG instillations.

[The advantages of combined US-fluoroscopic guidance in the drainage of abdominal abscesses].

The authors report their experience with 19 percutaneous drainages of abdominal abscesses in 19 patients. Six collections were in the subphrenic spaces, 6 in the liver, 1 in the infracolic space, 2 in the psoas muscle, 3 within the abdominal wall, and 1 in the pararenal space. Their etiology was abdominal surgery in 10 patients, biliary obstruction in 1, and trauma in 2; in the extant patients a hematogenous infection was supposed. The procedures were performed under combined US and fluoroscopic guidance, following Seldinger technique in all but two cases. Van Sonnenberg double-lumen sump catheter was successfully employed in all cases. After a review of the technique the authors discuss the advantages of US-fluoroscopic over CT guidance. The latter is preferred if the collection is not well demonstrated by US and in the cases where a posterior approach is needed. The economic advantages of US-fluoroscopic over CT guidance are also stressed.

Incidence and microbiology of abdominal and pelvic abscess in Crohn's disease.

The incidence of abdominal and pelvic abscess is reported from a consecutive series of 111 patients undergoing 124 resections for Crohn's disease. Preoperative abscesses were found as a complication of Crohn's disease in 13 patients (10%) and 8 were clinically unsuspected. The majority of preoperative abscesses were confined to one site (localized to bowel, psoas sheath, pelvis, or in the abdominal wall). All preoperative abscesses occurred in patients requiring an emergency or urgent operation. Patients with a preoperative abscess had significantly lower serum albumin levels and significantly increased serum alkaline phosphatase values than the patients without an abscess. Postoperative abscesses occurred in 17 patients (14%) and six were multiple. Five of the postoperative abscesses occurred in patients who had had a preoperative abscess; these recurrent abscesses all presented 6-14 wk after an uncomplicated initial operation. The principal bacterial isolates were Escherichia coli (54%), Bacteroides fragilis (44%), enterococci (41%), and viridans streptococci (31%). The incidence of abscess was unrelated to the use of preoperative steroid therapy.

Computed tomography evaluation of local and extraintestinal complications of Crohn's disease.

Complications of Crohn's disease were demonstrated by computed tomography of the abdomen and pelvis in 7 patients. Four patients had developed abscesses, 2 located in the psoas region and 2 involving the retroperitoneum or the liver. Other abnormalities documented on CT included inflammatory masses, fistulae, carcinoma, mesenteric thickening, and extraintestinal complications such as gallstones, renal calculi, and sacroileitis. Computed tomography was found to be useful in the detection and follow-up of abdominal complications of Crohn's disease.

Melioidosis, the great mimicker: a report of 10 cases from Malaysia.

Between 1981 and 1986, 10 consecutive cases of melioidosis were seen at the University Hospital, Kuala Lumpur, Malaysia. They illustrate the amazing guises of melioidosis presenting as: abscesses of the supraspinatus muscle, psoas muscle, brain and liver; three different pulmonary forms; an acute suppurative dermal lesion; an acute septicaemia; and chronic lymphadenitis. The majority had underlying diseases: diabetes mellitus, the commonest, was present in six, out of whom three had previous pulmonary tuberculosis; other predisposing conditions were renal failure, corticosteroid therapy and malnutrition. Three patients who died had pre-existing renal impairment and developed renal failure later, suggesting that the former is a bad prognostic sign. Clinical diagnosis was difficult: all cases were diagnosed bacteriologically. A high level of clinical awareness is necessary, especially when presentation simulates pulmonary or extrapulmonary tuberculosis in patients with diabetes or other compromised states.

Hip pain in patient with Crohn's disease. Occult retroperitoneal abscess as cause.

A 20-year-old man with Crohn's disease was seen as an outpatient for pain in the left hip and gait disturbance. Initially, arthritis of the hip was suspected, because of the absence of fever or abdominal abnormalities. Two weeks later, fever, malaise, and pneumaturia developed and urine culture grew Escherichia coli. Laparotomy revealed a large occult retroperitoneal abscess on the left side, which had been irritating the psoas muscle. Surgical drainage effected complete recovery of hip function. The abscess in this patient had a very unusual presentation and was diagnosed chiefly through a high index of suspicion after a careful physical examination.

[Abdominal actinomycosis. Actinomycotic abscess 10 years after appendectomy].

A case of actinomycosis of the abdomen ten years after surgery for acute appendicitis is reported. The patient, a 2 1/2 years old girl at the time of operation, presented with acute abdominal pain ten years after appendectomy. Computed tomography (CT) showed a mass in the region of the right psoas muscle. Fine needle aspiration revealed pus which on culture was found to contain Actinomyces israeli. Since surgery is a well known probable cause of abdominal actinomycosis, we must assume the appendectomy and the formation of the actinomycotic abscess to be related. Discovery of an abdominal mass even years after violation of the gastrointestinal tract should arouse suspicion of an abscess involving these otherwise infrequent pathogens.

[Non-vascular retroperitoneal emergencies].

Acute renal disease, in the absence of trauma, consist of acute renal obstruction, renal infection or a combination of the two. The diagnosis of acute renal colic is usually performed with ultrasound or excretory urography whereas parenchymal involvement in renal infection is best demonstrated on computed tomography images. The aim of radiologic investigations is to look for complications in order to guide the treatment, particularly percutaneous procedures. Other less common acute renal diseases include renal vein thrombosis optimally analyzed with contrast injection to demonstrate renal function, and spontaneous renal hemorrhage, which implies careful renal assessment looking for a small tumor. Acute psoas compartment diseases include hematomas and abscesses. Computed tomography is the best diagnostic tool and the examination of choice for the follow-up lesions and to guide percutaneous drainage.

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.

Acute appendicitis presenting as thigh abscess in a child: a case report.

A case of retrocecal appendicitis is described in a 6-year-old male child who presented with thigh abscess. The presence of a positive psoas stretch test, feculent discharge, an enteric growth on bacteriological examination, and intraabdominal fluid collection on abdominal ultrasound provided clues to the presence of an intraabdominal source of sepsis. Laparotomy revealed a perforated retrocecal appendix with surrounding collection communicating into the thigh. Appendectomy with drainage of retroperitoneal and thigh collections under adequate antibiotic coverage resulted in a satisfactory recovery. We describe our experience with the present case and discuss the pertinent literature.

Psoas muscle disorders: MR imaging.

Nineteen patients with evidence of psoas and iliopsoas abnormalities on computed tomographic (CT) scans (12 with metastases, three with lymphoma, two with hematoma, and two with abscess) were examined with magnetic resonance (MR) imaging. The abnormal psoas could be identified on both T1- and T2-weighted spin-echo images, although T2-weighted sequences provided better contrast. The psoas muscle can be affected by one of three mechanisms: total replacement, lateral displacement, or medial displacement. In four patients in whom the CT study showed apparent enlargement of a psoas muscle, subsequent MR imaging examinations demonstrated that the psoas muscle was compressed and displaced laterally by a paraspinal mass. MR images provided better contrast between the normal and abnormal psoas than CT scans in nine cases; MR images were inferior to CT scans in two cases because calcifications (one case) and air bubbles within an abscess (one case) were not detectable.

[The role of echography in osteolytic tubercular abscesses].

Tubercular abscesses are relatively common complications of tubercular spondylodiscitis. Fifty-one patients with suspected abscesses were selected from a group of 97 patients with tubercular spondylodiscitis and submitted to US. In 10 cases CT was performed before US and detected 7 abscesses, all of them confirmed by US. In the extant 41 cases, CT followed US; in 13 cases only US poorly visualized ilio-psoas muscles. As for the group of 23 patients who underwent both CT and US, if the former method is assumed as the reference gold standard, overall US sensitivity is 97% (1 false negative) and its specificity is 100%. In all cases where US findings were accurate and specific enough, CT was not performed; the patients were followed every seventh month and no abscesses found. US showed abscesses in the iliac fossa in 20 cases, along the psoas fascia in 6 and in the thighs in 3 cases. Two cases of gluteal localization were observed, together with 1 Grynfelt's triangle abscess, 1 Petit's triangle and 1 Scarpa's triangle abscesses; finally, 1 abscess was found in the knee. The most common appearance of tubercular abscesses is a hypoechoic and inhomogeneous pattern; sometimes caseum makes the abscess solid and hyperechoic. Calcifications were unusual in our series. All patients were submitted to percutaneous drainage under US guidance. The results proved US to allow the early and unquestionable diagnosis of tubercular abscesses and to confirm clinical suspicion. Moreover, US is also useful to guide percutaneous drainage and to follow the patients after drainage. As for CT, it remains the method of choice to depict vertebral involvement, but, in our series, it exhibited no significant advantages over US in the study of abscessual lumbar collections.

[Systemic lupus erythematosus presenting as a brainstem infarction and hemorrhage during treating retroperitoneal abscess: a case report].

We report a case of a brainstem infarction and hemorrhage seen in a 21-year-old female with systemic lupus erythematosus (SLE) during treating retroperitoneal abscess. SLE has been treated with prednisolone and mizoribine for 4 years. The patient with right back and lower abdominal pain visited our hospital. Computed tomography (CT) revealed retroperitoneal abscess over surrounding right kidney, horizontal part of duodenum and in front of psoas muscle. Drainage was done with indwelled right single J catheter and penrose drain. Retroperitoneal abscess was much smaller, but, post drainage day 17, high fever, unconsciousness, down-blood pressure and down-beat nystagmus appeared suddenly. Brain CT scan revealed a brainstem wide infarction and hemorrhage spot. Pulse therapy with steroid was done, however unfortunately the patient was dead after 6 days.

[Tuberculous spondylitis following BCG vaccination].

A case of a rare form of BCG osteomyelitis in the spine is presented. After vaccination, the disease started with a lymphadenitis. Later an abscess extended from the pelvic along the psoas muscles into the retroperitoneum. The soft tissue mass extended paraspinally and epidural involvement was also apparent. The vertebral involvement was detected by CT. The radiological findings are discussed with reference to the literature.
