Pyomyositis mimicking right iliac fossa mass: review of the literature.

Pyomyositis is a pyogenic infection of skeletal muscle. Its incidence in temperate countries though low is rising. Most cases from the temperate region involve immuno-compromised patients. The onset is usually insidious with progression to large purulent collections. Because of its low incidence in temperate countries, it is often initially misdiagnosed. A high index of suspicion with appropriate imaging techniques, aggressive surgical intervention and adjunctive antibiotic therapy are the keys to prompt resolution. A case of pyomyositis mimicking right iliac fossa (RIF) mass is described with a review of the literature.
