Retrorectal tumors are rare and frequently present either incidentally or with vague symptoms. Schwannomas of the presacral region are one variant described as benign tumors of neurogenic origin. The "ancient degenerative variant" is uncommonly reported. We present the case of a 37-year-old man presenting with symptoms of left renal colic, impotence, and left trochanteric pain. Computed tomography and magnetic resonance imaging of the pelvis showed a presacral mass with cystic changes and calcifications consistent with a schwannoma. The patient underwent an exploratory laparotomy with resection of the tumor, which subsequent analysis showed to be a schwannoma with ancient degenerative changes.
直肠后肿瘤罕见，常为偶然发现或伴有模糊症状。骶前区神经鞘瘤是一种被描述为神经源性起源的良性肿瘤变体。“古老退行性变体”报道较少。我们报告一例37岁男性，表现为左肾绞痛、阳痿和左转子疼痛症状。骨盆计算机断层扫描和磁共振成像显示骶前有一肿块，伴有囊性改变和钙化，符合神经鞘瘤表现。患者接受了 exploratory laparotomy（此处可能有误，推测为“剖腹探查术”）并切除肿瘤，后续分析显示为具有古老退行性改变的神经鞘瘤。
