Cysticercosis of the Pectoralis Major: A Case Report and Review of Literature.

Cysticercosis is a condition caused by the encysted larval form of Taenia solium (pork tapeworm). The commonest system affected is the central nervous system. Symptomatic primary muscle involvement is a rare phenomenon. We present a case of a 19-year-old male who presented with a solitary cystic swelling in the right infraclavicular area. Magnetic resonance imaging revealed a cystic mass in the right pectoralis major muscle. The cyst was excised and submitted for histopathology. The diagnosis of cysticercosis was confirmed on histopathology of the excised cyst.
