Methods CT imaging and clinical presentation of 16 patients with germ cell tumors confirmed by pathology were retrospectively reviewed. Results The CT findings showed as soft tissue mass with well-circumscribed inside scrotum. there have 10 cases seminoma, plain scan showed iso-to low density, after the inject of contrast medium the lesion showed mild to midrange enhancement, 6 cases showed internal necrosis, 2 cases showed calcification; 4 cases teratoma patients the age of onset is younger than 20 years, plain scan showed iso-to low density, all 4 cases showed internal calcification and 1 cases showed adipo, after the injection of contrast medium showed obviously uneven enhancement; endodermal sinus tumor have 2 cases, plain scan showed iso-to low density and after the injection of contrast medium showed mild to midrange enhancement. Conclusion CT can detect primary germ cell tumor
