Presacral schwannomas are a rare disease. The current case report presents a case of giant schwannoma with severe abdominal pain, constipation and dysuresia. The patient was initially diagnosed with an ovarian teratoma, which is an extremely common disease. The pain pattern and accompanying symptoms were the major factors indicating a teratoma. Abdominal computed tomography (CT) scans were the main tools of differential diagnosis, but the unsharpness of CT often disturbs diagnosis. Diagnosis of the tumor was confirmed by histopathology and immunohistochemistry, revealing a benign presacral schwannoma. The patient underwent complete resection and recovered well, albeit with a large amount of blood loss. The tumor was 25×15×10 cm in size and in contact with the sacrum. The aim of the present study was to review the diagnostic techniques of careful radiological examination. A follow-up was performed 2 years following the surgery and the patient remained alive and a CT scan demonstrated no evidence of recurrence. However, the long term efficacy of this process requires continuous observations of the patient.
骶前神经鞘瘤是一种罕见疾病。本病例报告展示了一例伴有严重腹痛、便秘和排尿困难的巨大神经鞘瘤病例。该患者最初被诊断为卵巢畸胎瘤，这是一种极为常见的疾病。疼痛模式及伴随症状是提示畸胎瘤的主要因素。腹部计算机断层扫描（CT）是鉴别诊断的主要手段，但CT图像不清晰常干扰诊断。肿瘤诊断经组织病理学和免疫组化得以证实，结果显示为良性骶前神经鞘瘤。患者接受了完整切除，虽失血量大，但恢复良好。肿瘤大小为25×15×10厘米，与骶骨相连。本研究的目的是回顾细致的放射学检查诊断技术。术后两年进行了随访，患者存活，CT扫描未显示复发迹象。然而，这一过程的长期疗效需要对患者进行持续观察。
