Cysticercosis of Sternocleidomastoid Muscle Presenting as a Neck Swelling - A Rare Case Report

Cysticercosis is an infection of Cestodes, or tapeworms (larvae), which are segmented worms. The adults reside in the gastrointestinal tract, but the larvae can be found in almost any organ. We present a case of an adult presenting as cystic neck swelling which turned out to be cysticercosis of sternocleidomastoid muscle. On evaluation using USG, FNAC cysticercosis was diagnosed and the same was confirmed by histopathological examination. Hence we conclude that parasitic infestation should be considered as differential diagnosis in any neck swelling.
