Schwannomas are benign tumors originating from Schwann cells, with seminal vesicle schwannomas being exceedingly rare. This report describes a 54-year-old man with an incidental discovery of a right-sided seminal vesicle mass during a routine ultrasound examination. Further imaging, including MRI and contrast-enhanced CT scans, revealed a well-defined, encapsulated mass with heterogeneous signal intensity suggestive of schwannoma. Histopathological examination confirmed schwannoma, marked by positive S-100 and NSE expression and a Ki67 index of 5%. The patient underwent successful laparoscopic resection without complications and remained asymptomatic for over a month. This case underscores the importance of integrating MRI and histopathological findings to accurately diagnose seminal vesicle schwannomas and guide appropriate surgical management, highlighting the need for increased clinician awareness of this rare tumor.
神经鞘瘤是起源于施万细胞的良性肿瘤，精囊神经鞘瘤极为罕见。本报告描述了一名54岁男性，在常规超声检查中意外发现右侧精囊肿物。进一步的影像学检查，包括MRI和增强CT扫描，显示出一个边界清晰、有包膜的肿物，信号强度不均匀，提示为神经鞘瘤。组织病理学检查证实为神经鞘瘤，其特征为S-100和NSE表达阳性，Ki67指数为5%。患者成功接受了腹腔镜切除术，无并发症，术后一个多月无症状。该病例强调了综合MRI和组织病理学检查结果以准确诊断精囊神经鞘瘤并指导适当手术治疗的重要性，凸显了临床医生提高对这种罕见肿瘤认识的必要性。
