Solitary Atypical Myocysticercosis in the Trapezius Muscle: A Case Report

Abstract

One of the most dangerous parasitic infections found practically everywhere in the world is cysticercosis, which is also considered a neglected tropical disease. Cattle are the intermediate hosts in the life cycle of the parasite that causes cysticercosis, known as Cysticerci, which is the larval form of the beef tapeworm Taenia saginata. When raw or undercooked meat is consumed, human cysticercosis develops, turning the person into an unintentional intermediate host. In areas with inadequate sanitation, cysticercosis is endemic. Although human cysticercosis is becoming less common due to improved living and hygiene conditions, the primary locations of these cysts are in the skeletal muscles and subcutaneous tissues. Such cases are, however, sometimes observed. It is uncommon for a young male to exhibit involvement of the trapezius muscle. In this case report, we present an incidental diagnosis of myocysticercosis. The patient underwent radiological investigation, and surgical excision was successfully performed. We emphasize the importance of diagnostic work-up, management, and follow-up, as well as the need for a clinical suspicion of parasitic infestation in settings similar to ours for better management.
