A 39-year-old female patient with a slowly growing painful lesion in the midcalf. Ultrasound with power Doppler (PwD) along the long axis of the lesion demonstrates an oblong hypoechoic mass with intense PwD signal and posterior acoustic shadowing.

Gross specimen from surgical excision and debridement demonstrates the empty cavity and a bag-like structure that contained the larva. The larva is adjacent, black, and oval with rows of caudal barbs that allow embedding in the tissue.
