Isolated cysticercosis cellulosae of sternocleidomastoid muscle: a case report with review of literature.

Human cysticercosis is an infection by the larval stage of the tapeworm. We encountered a rare case of isolated cysticercosis of sternocleidomastoid muscle in a 25 year old female. She presented with 2.5 × 1.5 cm firm, dull aching swelling with ill defined margins in right upper part of neck. It appeared to arise in sternocleidomastoid muscle. The diagnosis was established by FNAC, USG and CT scan. Patient was admitted and started on medical treatment. There was complete resolution of symptoms and patient improved to normal after 1 month of therapy with albendazole. The case is reported because it is a rare one and to reinforce the fact that parasitic etiology should be kept in mind while dealing with a case of neck swelling.
