Seminomas are the malignant testicular tumors most commonly diagnosed in young adult males. It consists of undifferentiated cells derived from the embryonic gonad. The tumor presents as a scrotal mass that may or may not be associated with pain. On ultrasonography, the mass appears hypoechoic with well-defined margins and an echo structure that tends to be homogeneous. Color Doppler studies reveal rich vascularization. This report describes a case of seminoma that presented with scrotal pain. The typical findings on ultrasonography and color Doppler were fundamental for correct diagnosis of this tumor.
精原细胞瘤是最常发生于年轻成年男性的恶性睾丸肿瘤。它由源自胚胎性腺的未分化细胞组成。该肿瘤表现为阴囊肿块,可能伴有疼痛,也可能不伴有疼痛。超声检查时,肿块呈低回声,边界清晰,回声结构趋于均匀。彩色多普勒检查显示血管丰富。本报告描述了一例以阴囊疼痛为表现的精原细胞瘤病例。超声检查和彩色多普勒的典型表现对于该肿瘤的正确诊断至关重要。
