title: The management of psoas abscess.
abstract: 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.
