Introduction- Cysticercosis - A helminthic infestation caused by Taenia solium (pork tapeworm), can produce central nervous system, muscles, visceral, subcutaneous tissues and skin manifestations. Cysticercosis in muscles does not cause any symptoms. However, one may feel lump under the skin, Solitary intramuscular cysticercosis without involvement of central nervous system is a rare entity. We present two cases of solitary intramuscular cysticercosis, without any systemic or neurological manifestations.
Discussion - Human cysticercosis is an infection by the tapeworm Taenia solium. It is seen in central and South America, Africa, India, and China. Tapeworm infection is commonly seen in developing countries due to a combination of factors like rural society, crowding and poor sanitation allowing greater contact between humans and pigs. Infection with the adult worm takes place by the ingestion of uncooked or ill- cooked pork containing larvae of Taenia solium.
Conclusion - Cysticerci can develop in any voluntary muscles in humans. Invasion of muscle by cysticerci can cause myositis, with fever, eosinophilia, and muscular pseudohypertrophy, which initiates muscle swelling and later progress to atrophy and fibrosis. In most cases, it is asymptomatic since the cysticerci die and become calcified. Painful and bothersome cysts can be surgically removed.
