Serous borderline tumor (SBT) of the testis is a rare, ovarian epithelial-type tumor of the testis. We present a case of SBT after radical orchiectomy in a 59-year-old man who had 3-month progressive enlargement of his right hemi-scrotum, negative testicular tumor markers and scrotal ultrasound equivocal for malignancy. Magnetic resonance imaging (MRI) of the pelvis was obtained to aid with evaluation and showed marked hyperintensity on T2-weighted images with frond-like nodular peripheral enhancement within right testis mass. These distinct MRI findings can help clinicians differentiate SBT from other testis tumors. Relapse has not been observed in 8 years of follow-up.
睾丸浆液性交界性肿瘤（SBT）是一种罕见的睾丸卵巢上皮型肿瘤。我们报告一例59岁男性患者，在根治性睾丸切除术后发生SBT。该患者右侧半阴囊进行性肿大3个月，睾丸肿瘤标志物阴性，阴囊超声检查对恶性肿瘤的判断不明确。盆腔磁共振成像（MRI）用于辅助评估，结果显示右侧睾丸肿块在T2加权图像上呈明显高信号，周边有叶状结节样强化。这些独特的MRI表现有助于临床医生将SBT与其他睾丸肿瘤区分开来。随访8年未观察到复发情况。
