Abstract

Objective: This study aims to illustrate a rare case of retroperitoneal schwannoma by presenting the clinical, imaging, and histological parameters.

Case report: A 36-year-old patient visited the outpatient clinic because of back pain experienced over the previous two months. There were no complaints regarding the nervous system or urinary system. Thorough imaging evaluation, including magnetic resonance for the lumbar spine, abdominal computed tomography, and positron emission tomography was conducted. An encapsulated mass was found in the retroperitoneal area, positioned in front of the O4 vertebra and in close proximity to the left psoas muscle, the left common iliac artery, and the left ureter. The lesion exhibited FDG radioisotope uptake, and a CT-guided biopsy confirmed a benign peripheral nerve tumor. The patient underwent laparotomy surgery, where the tumor was removed. The histological investigation, along with immunohistochemistry, confirmed the presence of a retroperitoneal schwannoma.

Conclusion: Schwannoma is a rare type of retroperitoneal tumor, with nonspecific clinical and radiological characteristics that make diagnosis difficult. Surgical resection is the primary treatment for symptomatic patients, with a favorable prognosis. Long-term follow-up is advised to reduce the chance of late recurrence.

一例罕见的成年男性腹膜后神经鞘瘤。
目的:本研究报告一例罕见的腹膜后神经鞘瘤的临床、影像及组织学资料。病例报告:一名36岁的患者因前两个月的背部疼痛到门诊就诊。没有关于神经系统或泌尿系统的抱怨。进行了全面的影像学评估,包括腰椎磁共振,腹部计算机断层扫描和正电子发射断层扫描。在腹膜后区发现一个包裹性肿块,位于O4椎体前部,靠近左侧腰肌、左侧髂总动脉和左侧输尿管。病变表现为FDG放射性同位素摄取,ct引导活检证实为良性周围神经肿瘤。病人接受了剖腹手术,肿瘤被切除了。组织学检查,连同免疫组织化学,证实存在腹膜后神经鞘瘤。结论:神经鞘瘤是一种罕见的腹膜后肿瘤,其临床和影像学特征非特异性,给诊断带来困难。手术切除是有症状患者的主要治疗方法,预后良好。建议长期随访,以减少晚期复发的机会。
