title: Pelvic osteomyelitis mimicking septic hip arthritis: a case report.
abstract: Peripelvic infections are rare, compared with the incidence of septic hip arthritis, but are serious, requiring emergent treatment. They often are not included in differential diagnoses for patients presenting with fever, pain, inability to bear weight, elevated white blood cell count, and elevated erythrocyte sedimentation rate. Most patients are treated initially as a septic hip arthritis. Early diagnosis and treatment are crucial to outcome in peripelvic abscess. Use of MRI may help to elucidate the correct diagnosis. Previously reported peripelvic infections included obturator internus and externus, and psoas, but to the best of our knowledge, this is first case report of infection of the ischiopubic ramus synchondrosis presenting as septic arthritis.
