Pneumococcal psoas abscess: Report of a case and review of the world literature

A 39-year-old man was admitted to the hospital with fever and right hip pain. CT scan of the pelvis showed a psoas muscle abscess. Pus, which was surgically evacuated, grew Streptococcus pneumoniae. The patient fully recovered after 30 days of intravenous antibiotics. Review of the literature revealed only nine similar cases of primary pneumococcal psoas abscess. Three cases were complicated with pneumococcal meningitis. In four cases there was a history of trauma to the involved area. Pneumococcal psoas abscess is a rare entity that carries a good prognosis provided early surgical drainage is performed and parenteral antibiotic therapy is administered to the patient.
