Pyogenic sacroiliitis in Qatar.

We describe our experience in handling six cases of pyogenic sacroiliitis. Two were males and four were females with a mean age of 24.9 years. None had a history of i.v. drug abuse. Blood cultures were positive in half of the patients. The sacroiliac joint aspirate was positive in one additional patient. Staphylococcus aureus was recovered from three of four culture positive cases. Bone and CT scans revealed abnormalities in all patients. Response to antibiotic therapy was satisfactory in all except one patient who had an early relapse. Early diagnoses and proper treatment would result in improved outcomes.
