Sparganosis in the scrotum: Sonographic findings

Sparganosis is a rare parasitic disease that is caused by the larva, sparganum, of the genus Spirometra. It usually manifests as a mass in various locations, such as the brain, eyelids, oral cavity, pleura, breast, abdominal wall, scrotum, and skeletal muscle of the lower extremities. It tends to mainly involve the subcutaneous tissue. Hence, sonography can play a major role in diagnosing this entity. However, there are few case reports of the sonographic findings of sparganosis involving the breast and the lower extremities. To our knowledge, there is no report describing the detailed sonographic findings of scrotal sparganosis. Here, we describe a case of scrotal sparganosis with the sonographic findings.
