Forearm mystery: rare flexor carpi radialis muscle cysticercosis.

This case report describes a rare instance of muscle cysticercosis in a 16-year-old vegetarian female from an endemic region, highlighting the challenges in diagnosing atypical presentations of the disease. The patient presented with a 2-month history of persistent pain and swelling in the right forearm, which did not respond to over-the-counter analgesics. A clinical examination identified a non-tender, immobile swelling, and imaging studies suggested cysticercosis. Despite treatment with albendazole and non steroidal anti-inflammatory drugs (NSAIDs), the swelling persisted, necessitating surgical intervention. The excised cyst was confirmed as cysticercosis through histopathological examination. This case underscores the importance of considering cysticercosis in the differential diagnosis of soft tissue swellings, particularly in endemic areas, and emphasizes the role of imaging and histopathology in ensuring accurate diagnosis. Preventive measures such as improved sanitation and hygiene are crucial in controlling the spread of cysticercosis.
