Sonographic appearance of benign intratesticular lesions

58 patients with a purely intratesticular lesion were investigated with scrotal ultrasound. A pathognomonic echo pattern could be found for simple parenchymal cysts and hemangiomas only. The nature of all other lesions (chronic orchitis, hematoma, epidemoid cyst, testicular necrosis, abscess and tuberculosis) could not be defined solely on sonographic grounds.
