Diagnosis of Iliopsoas Pyomyositis by Ultrasonography and CT

Abstract

A patient with iliopsoas muscle pyomyositis was successfully treated with intravenous antibiotics alone. The diagnosis was made by ultrasonography and X-ray computed tomography after five days of spiking fevers. Ultrasonography and X-ray computed tomography revealed swelling of the muscle body but no abscess formation. We emphasize the usefulness of early diagnostic imaging to allow conservative treatment of iliopsoas muscle pyomyositis.
