Case reports

A 45-year-old male patient had a tender 2 week swelling of 4 × 5 cm on medial right proximal calf. A 26-year male presented with discomfort and diffuse 6 cm swelling at inner left forearm. In both ultrasound showed characteristic hypoechoic cyst with hyperechoic scolex, and MRI revealed isolated cyst surrounded by inflamed muscles. FNAC confirmed cysticercosis, and the patient responded to oral albendazole (3 weeks) with oral steroids (2 weeks).


Although rare, possibility of isolated muscular cysticercosis should always be considered in any small musculoskeletal soft tissue swelling presenting with nonspecific clinical findings. Both our patients responded to medical therapy and were disease free, as confirmed at 3 months by follow-up MRI. These cysts can be confidently diagnosed on the basis of ultrasound and MRI, and can be very well-treated nonsurgically with an oral drug regimen consisting of albendazole and steroid.
