We report a case of intra-abdominal seminoma in an undescended testis, focusing on the radiological clues for diagnosis on computed tomography. A 49-year-old man visited our hospital with a palpable abdominal mass and underwent abdominopelvic computed tomography. Computed tomography demonstrated an ovoid, mildly enhanced, well-defined mass measuring 21 × 16 × 9 cm in the small bowel mesentery mimicking a mass of mesenteric origin. However, a vascular structure was observed in the left posterior aspect of the mass. The vascular structure originated from the inferior posterior part of the mass and ran cranially. The artery subsequently united to the aorta, and the vein united to the left renal vein. We identified the artery and vein as the testicular artery and vein, respectively. We also noted the absence of a left spermatic cord in the left inguinal canal. Therefore, we concluded that the mass originated from the left undescended testis. The patient underwent surgery, and the mass was removed with the testicular vessels; the resected testicular vein was mostly filled with thrombus. On pathological examination, the mass was confirmed to be a seminoma in the undescended testis.
我们报告一例隐睾内腹腔内精原细胞瘤病例，重点关注计算机断层扫描（CT）上的诊断影像学线索。一名49岁男性因可触及腹部肿块就诊于我院，并接受了腹盆腔CT检查。CT显示在小肠系膜内有一个椭圆形、轻度强化、边界清晰的肿块，大小为21×16×9 cm，类似肠系膜来源的肿块。然而，在肿块的左后方观察到一个血管结构。该血管结构起源于肿块的后下部并向头侧走行。动脉随后与主动脉相连，静脉与左肾静脉相连。我们分别将动脉和静脉确定为睾丸动脉和静脉。我们还注意到左侧腹股沟管内没有左侧精索。因此，我们得出结论，该肿块起源于左侧隐睾。患者接受了手术，连同睾丸血管一起切除了肿块；切除的睾丸静脉大部分充满血栓。病理检查证实该肿块为隐睾内的精原细胞瘤。
