Unilateral psoas abscess following posterior transpedicular stabilization of the lumbar spine.

A case of unilateral psoas abscess in a 58-year-old patient, shortly after posterior lower spine stabilization and fusion for spinal stenosis using transpedicular spine fixation is reported. The diagnosis was delayed because the patient's symptoms were referred to the thigh and the plain roentgenograms were negative for pathology. The technetium scintigram and computed tomography (CT) helped localization, diagnosis and treatment of the psoas abscess. Percutaneous CT-guided drainage was followed by recurrence of the abscess, and open surgical evacuation was performed successfully in combination with antibiotic treatment for 8 weeks. Psoas abscess should always be suspected when recurrent pain is associated with fever and elevated erythrocyte sedimentation rate after instrumentation of the lumbar spine. Hardware of a low profile and volume should be used to decrease dead space in the fusion area, and the volume of bone substitutes should be limited for the same reason.

[Treatment of psoas abscess. Report of a case and review of the literature].

Psoas abscess is an infrequent disease. We present a right psoas abscess diagnosed in a thirteen-year-old child. There wasn't a history of known trauma nor immunodeficiency. We didn't find another infection focus so the abscess was described as primary one. This is the most commonly presentation in children. Staphylococcus aureus was the bacteria identified in blood culture. The presenting symptoms were bottom and hip pain, limp and fever. The differential diagnosis was established with suppurative arthritis of the hip. Diagnosis was confirmed by Magnetic Resonance. In regard to treatment the patient was exclusively treated with systemic antibiotics, high spectrum of activity. The patient didn't require percutaneous-drainage. Though surgical drainage wasn't made, evolution was favourable and recurrence wasn't observed.

[Psoas abscess secondary to lumbar spondylodiscitis caused by gram negative bacilli].

The association between psoas abscess and lumbar spondylodiscitis by Gram negative bacilli represents a rare clinical entity. Sometimes the absence of demonstrative symptoms complicates the diagnostic schema. We report about a 72 year-old woman, without previous known diabetes mellitus, who was admitted because of fever of one week duration and a non-ketotic hyperosmolar coma. A left psoas abscess was identified by abdominal computed tomography (CT). The abscess was in communication with the L1-L2 intervertebral space. Although Escherichia coli was identified as the causing agent and appropriate antibiotic therapy was administered, the resolution of the abscess occurred only after the implantation of a percutaneous catheter guided by CT without additional surgery. Percutaneous drainage as a diagnostic-therapeutic technique has rendered the surgery as the last resort in the treatment of psoas abscess.

Ilio-psoas abscess in the paediatric population: treatment by US-guided percutaneous drainage.

BACKGROUND: Image-guided percutaneous drainage has been shown to be a safe and effective alternative to surgery in the management of psoas abscess in adults and adolescents. There is little information on its use in children. OBJECTIVE: To evaluate the safety and efficacy of US-guided percutaneous needle aspiration and catheter drainage of ilio-psoas abscesses. MATERIALS AND METHODS: A retrospective review of 14 children with 16 ilio-psoas abscesses (10 pyogenic and 4 tuberculous) who were treated by US-guided percutaneous needle aspiration (n = 5) or catheter drainage (n = 9) along with appropriate antimicrobial therapy. RESULTS: Percutaneous treatment was successful in 10 of the 14 patients; all showed clinical improvement within 24-48 h of drainage and subsequent imaging demonstrated resolution of the abscess cavities. Surgery was avoided in all of these ten patients except one, who underwent open surgical drainage of ipsilateral hip joint pus. Of the other four patients, two had to undergo surgical drainage of the ilio-psoas abscesses after failure of percutaneous treatment, one improved with antibiotics after needle aspiration failed to yield any pus, and one died of continuing staphylococcal septicaemia within 24 h of the procedure. There were no procedural complications. CONCLUSIONS: Percutaneous drainage represents an effective alternative to surgical drainage as a supplement to medical therapy in the management of children with ilio-psoas abscesses.

A case of bilateral psoas abscesses and lumbar osteomyelitis due to recurrent salmonella infection.

Psoas abscess and lumbar osteomyelitis due to salmonella infection is very rare, although it is frequently seen all over the world. These two complications have severe clinical progress, poor prognosis and high mortality. Here, we report a case of salmonellosis presenting with bilateral multiple psoas abscesses and lumbar osteomyelitis, which resolved completely following medical treatment and percutoneous drainage of abscess.

[Giant psoas abscess with aggressive extension: report of a case].

We report a case of giant psoas abscess with aggressive extension outside the muscles of the iliopsoas component. A 57-year-old man was admitted to our hospital, presenting with right flank pain and severe general malaise. He had been diabetic, but no treatment had been performed for diabetes. Leukocytosis, positive CRP and hyperglycemia were noted, but he was nearly afebrile on admission. Computerized tomography revealed a large multilocular mass in the right retroperitoneal space involving the ipsilateral psoas muscle. The diagnosis was not apparent until the 12th hospital day, when moderate grade fever was noted and brownish purulent fluid was obtained by percutaneous puncture of the mass. Staphylococcus aureus was isolated on culture. Antibiotic chemotherapy was started, and ultrasound-guided percutaneous drainage was then performed under the diagnosis of psoas abscess. At that time, the abscess was aggressively extending from the iliopsoas component into the pelvic floor, involving the rectus muscle, the gluteal muscles and formation of subucutaneous lesions. At 46 days after drainage, surgical resection of the abscess with removal of the adjucent tissue was performed because of persistent discharge of pus and multiple residual lesions. The postoperative course was uneventful, and there has been no recurrence. Many cases of psoas abscess have been reported in the Japanese literature. Prompt drainage, either percutaneously or surgically are required. Surgical resection of the abscess, with not only opening the cavity but also removal of the adjacent tissue, may be recommended in some cases, especially those diffuse or multilocular lesions.

Psoas abscess: difficulties encountered.

From 1961 to 1989, 67 patients underwent various surgical procedures for psoas abscess. Retrospective analysis was undertaken in an effort to determine optimal surgical therapy. Forty patients were cured with one operation. Twenty-one patients required two operations, four patients required three operations, and two patients required more than three operations. The reason for failure of treatment was failure to resect the diseased bowel or to drain the psoas abscess adequately. A technique to recognize and treat the abscess definitively will be illustrated. The most common etiologies were Crohn's disease in 49 patients, postoperative sepsis in eight patients, and complications of renal disease in four patients. The length of hospital stay ranged from 5 to 392 days (mean, 26 days). There were two deaths. Failure to recognize and treat psoas abscess results in considerable morbidity.

The management of psoas abscess.

The presentation and management of psoas abscess was studied prospectively in 5 patients and retrospectively in 4. 3 patients had bilateral abscesses. All patients had back pain and a mass in loin or iliac fossa. 7 patients had no hip findings. One patient had a perinephric abscess and another had radiological features of tuberculosis of the spine. In the other seven no cause for the abscess could be identified. Ultrasonography demonstrated the abscess in all patients; CT scanning done in 5 patients was confirmatory. Drainage was done by an extraperitoneal route. Biopsy of the abscess wall in 2 patients demonstrated tuberculosis. They, the patient with TB spine and 3 others put empirically on anti-tuberculosis chemotherapy responded well. The perinephric abscess grew Pseudomonas sensitive to gentamycin, but she and two other patients died due to multiorgan failure.

[Primary psoas abscess in children: 6 cases].

BACKGROUND: Primary psoas abscess is very rare in childhood; its diagnosis and treatment can be improved by the use of recent imaging techniques. PATIENTS: Six children, aged 11 months to 10 years (mean: 51 months) were admitted from January 1987 to 15 December 1993 because they suffered mainly from fever, lumbar pain and/or homolateral flexed hip. Examination showed a painful inguinal mass in five patients and hyperleucocytosis in all. X-rays showed disappearance of the external limit of psoas in two patients; ultrasonography showed enlarged psoas in all, associated with hypoechogenic mass in two and without echo in four patients. CT scan showed the abscess in all cases, permitting a needle aspiration for bacteriological studies: Staphycococcus aureus was present in five cases. Drainage of the abscess by CT-guided percutaneous catheter was performed in two patients. Surgical drainage was performed in three including one for whom percutaneous catheter drainage did not succeed. The two other patients were only given antibiotics. CONCLUSION: CT-guided needle aspiration to establish presence and nature of fluid collection is a well established technique that may be extended to treatment of psoas abscesses.

[The voluminous primitive psoas abscess in children: report of three cases].

The primitive psoas abscess is a pathology extremely rare in the child. The diagnosis is difficult and often delayed. Their treatment requires a local and general sterilization of the infection. We report three observations of primary abscess of the psoas in the child. The clinic presentation is uncommon. Ultrasonography keeps an important place. The biology objective an infectious and inflammatory syndrome. Histology permits to put in evidence all shapes association of lesions. The bacteriological survey of the pus after drainage is only positive in one case. Surgical drainage with bactericidal antibiotherapy permit a definitive recovery.

Psoas abscess as a complication of pyogenic sacroiliitis: report of a case.

A psoas abscess is, either primary or secondary, a rare entity for a general surgeon. Images by ultrasonography and computed tomography (CT) can help a general surgeon to make an accurate diagnosis when encountering the patient complaining of unilateral lower abdominal deep pain with fever. A case of pyogenic abscess of the psoas muscle as a result of sacroiliitis in a 22-year-old man is reported herein. The abdominal CT and magnetic resonance imaging scans demonstrated a large multilocular abscess extending along the iliopsoas muscle, and erosion and a widening of the left sacroiliac joint. The abscess was drained with an open surgical approach and the patient responded well to antibiotic therapy. Aggressive surgical and medical treatment is necessary in patients with psoas abscess to prevent complications.

Psoas abscess in rheumatoid arthritis--an inperspicuous diagnosis.

Primary or secondary psoas abscess is infrequently seen but should not be forgotten. We report on two patients with RA who presented predominantly with back pain and who subsequently developed pyrexia. The correct diagnosis of psoas abscess was not immediately apparent. These cases and the discussion and comments which follow illustrate the difficulties that may be encountered and remind readers of this inperspicuous diagnosis.

Primary psoas abscess--diagnostic and therapeutic considerations.

OBJECTIVE: To present our experience of the diagnosis and treatment of primary psoas abscess in India. PATIENTS AND METHODS: Between July 1993 and December 1995, five men (aged 24-67 years) presented with suspected primary psoas abscess. All five patients had fever with or without rigors and upper/lower abdominal pain of varying duration (2-6 weeks). RESULTS: The presentation in all patients was conspicuous by the absence of the classical signs of limping and positive psoas symptoms. Computed tomography (CT) was the best method of diagnosis, being accurate in every case. Antibiotics alone (two patients), or in combination with percutaneous aspiration, were curative. CONCLUSIONS: This small series of five patients of primary psoas abscess was remarkable in that all the patients were men and three were elderly. The classical symptom of limping was absent in all. The urologist can be misled by loin pain and irritative lower urinary symptoms in the patients, resulting in a delay in diagnosis and management.

Psoas abscess related to spontaneous abortion, intra-uterine contraceptive device and curettage.

This case report presents a patient with a psoas abscess related to a dilatation and (aspiration) curettage for an incomplete abortion with an IUD. Psoas abscess is extremely rare in obstetrics and gynecology and a life threatening condition. It is important to recognize the clinical presentation. Psoas abscess should be suspected in patients presenting with fever, pain in the leg, thigh, or low back region. Whether antibiotic prophylaxis in abortion curettage may prevent this and other complications is discussed.
