It can be divided into primary tumors and secondary tumors (lymphoma, leukemia, and metastasis). Primary tumors can be also classified into testicular germ-cell tumors and testicular nongerm-cell tumors. MR imaging is an important imaging tool in the evaluation of scrotal masses, in addition to ultrasound.
Most intratesticular solid masses represent malignant tumors, whereas 97 % of the extratesticular masses are benign.
Germ-Cell Tumors (95 % of Testicular Carcinomas)
They are categorized as seminoma or nonseminomatous tumor. Nonseminomatous germ-cell tumors include embryonal carcinoma, yolk sac tumor, teratoma, and choriocarcinoma.
US is the best diagnostic tool to identify and characterize scrotal mass. Seminomas tend to be homogeneous in echotexture, whereas nonseminomatous germ-cell tumors are more heterogeneous. CT is the study of choice for the evaluation of retroperitoneal adenopathies and lung metastasis.
Seminomas are isointense to normal tissue on T1- and...
