Abdominal abscess following asymptomatic pelvic osteomyelitis. Case report.

In a 23-year-old woman, an intramuscular abscess of the ventral abdominal wall in the right iliac fossa was found to have an extraperitoneal fistula to a focus of asymptomatic osteomyelitis of the iliac ala. Pelvic osteomyelitis should be suspected in cases of abdominal wall abscess without pathologic intra-abdominal findings.
