A Case Report of Isolated Cysticercosis of Biceps Muscle

Cysticercosis is more commonly seen in developing countries like India caused by larval stage of Taenia solium. Neurocysticercosis is more commonly seen than isolated muscle involvement. There are very few sporadic cases of isolated biceps muscle involvement, but most of them are managed medically. We are reporting an isolated case of cysticercosis of biceps muscle managed surgically.

A 32-year-old male, security personnel by occupation, comes with complaints of painful swelling of the right arm for past 1 week. There was no trauma to the limb and no similar swellings elsewhere in the body. On examination, there was an anteromedial tender swelling of mid-third of arm. X-ray was normal with soft tissue shadow on the anterior aspect. Ultrasound showed cystic lesion with central hyperechoic lesion. Magnetic resonance imaging of arm showed 7.7 mm × 4.8 mm lesion in anteromedial aspect of arm with surrounding edema s/o granuloma. The patient underwent excision of the cyst and biopsy was suggestive of cysticercosis and surrounding granuloma.

Isolated cysticercosis of muscle is very rare, but when it is symptomatic and hindering in daily activities, surgical excision can be done for faster relief and early return to normal day-to-day activities.
