Pulmonary cysticercus.

Abstract

Cysticercus cellulosae, the encysted larva of Taenia solium, is reported in a solitary granulomatous lesion excised from the lung of a 61-year-old woman from Thailand. No extrapulmonary signs of cysticercosis were manifest preoperatively, and the diagnosis was not suspected clinically. Pulmonary cysticercus is rarely diagnosed histologically. When unaccompanied by extrapulmonary disease, a single cysticercus lung lesion may be clinically and radiologically indistinguishable from other granulomata and malignancy.
