MASSETER MUSCLE CYSTICERLOSIS: A CASE REPORT

Abstract

A 16-year-old male presented swelling in the left posterior region of the mandible with approximately one year of evolution. A hardened and palpable nodule was observed in the left masseter region, painless and associated with swelling. On ultrasound, a hypoechoic intramuscular nodular formation was identified with a central hyperechoic area located in the left masseter. Face tomography showed heterogeneous calcified formations with a slightly hypodense halo around it, suggestive of muscular cysticercosis. The patient underwent surgical excision of the lesions through an intraoral access in the jugal mucosa with exploration of the masseter muscle and four calcified nodules were removed. The diagnostic hypothesis was confirmed in an anatomopathological report. The patient evolved with a decrease in the swelling, without pain and with the absence of palpable nodules on the face. No calcification was identified in a control tomography after one year A 16-year-old male presented swelling in the left posterior region of the mandible with approximately one year of evolution.
