Abstract

Obturator internus pyomyositis is a rare disease that is more commonly found in tropical countries. Due to its infrequent occurrence, it is a differential of hip pain that has not been sufficiently considered, which often results in delayed diagnosis. We present a case report of a 4 year old boy with pyomyositis of obturator internus as well as externus. He was treated successfully with intravenous antibiotics. A comparison is made with other case reviews to identify symptoms and signs that could help in diagnosing the condition early and accurately so as to initiate intravenous antibiotics, the mainstay treatment in a timely fashion, eventually avoiding surgical drainage of the sequelae when it becomes an abscess.

Key words: Obturator internus pyomyositis, septic arthritis.
