title: Scrotal sparganosis: with an emphasis on ultrasonographic findings.
abstract: Scrotal sparganosis is a rare parasitic infestation in which humans serve as the second intermediate host for a tapeworm of the genus Spirometra. We present one case of a 44-year-old man with an emphasis on the ultrasound (US) findings. The patient had a palpable scrotal subcutaneous nodule and a history of eating raw snakes 7 years prior. On US, we noted a well-defined, long, tubular, serpiginous lesion that had three different echoic layers, i.e., a peripheral low echoic rim, an intermediate high echoic line, and an inner slightly low echoic content that had a tram-tract appearance.
