Sonographic appearance of cysticercosis of the masseter muscle: A case report

Abstract

Cysticercosis is an infection with the larval (cysticercus) stage of Taenia solium. The larvae form cysts commonly in brain, meninges, and eyes, which together constitute 86% of cases with remainder located in the muscles, heart, lungs, and peritoneum. Cases in the maxillofacial region, including tongue and cheek muscles are rare. We report a rare case of cysticercosis involving right masseter muscle presenting as a facial swelling, diagnosed on the basis of fine-needle aspiration cytology and high-resolution ultrasonography and managed conservatively.
