title: Sonography of unusual extratesticular lesions.
abstract: Sonograms of seven patients with extratesticular lesions are presented because of their relatively rare occurrence or unusual sonographic pattern. The sonographic appearance of a malignant extratesticular liposarcoma is described. Infected sebaceous glands and slow-growing malignant tumors of the spermatic cord are demonstrated as possible problems in differential diagnosis. Extratesticular septated cysts or fluid collections surrounding the spermatic cord are documented as complications in hemophilia and acute pancreatitis. These entities are presented because of their differential diagnostic challenge compared with more common disorders such as infected hydroceles and hernias.
