Case report: Lower extremity sparganosis in a bursa.

Abstract

Sparganosis is a rare parasitic infection caused by the plerocercoid tapeworm larva of the genus Spirometra. We report the case of a 67-year-old man with a mass over the anteromedial surface of the proximal extremity of the tibia. We surgically excised a bursa containing Spirometra larvae. Sparganosis is a rare parasitic infection. We found no cases of lower extremity sparganosis combined with bursitis reported in the literature. Sparganosis should be considered in the differential diagnosis of soft tissue tumors, especially among patients who frequently have consumed mountain water or raw snakes or frogs.
