Schwannomas are benign tumours that arise from the Schwann cells of nerve fibres. They commonly occur in the head and neck, mediastinum and extremities. They are extremely rare in the pelvis. These are usually slow-growing tumours and are often detected incidentally. Preoperative diagnosis is extremely difficult as there are no definitive signs on imaging. Aspiration biopsy is often inconclusive or misleading. Surgical excision is both diagnostic and therapeutic. As these tumours are often large in size, open excision is most commonly performed. We describe a case of a large, cystic schwannoma of the pelvis causing bladder outlet obstruction and bilateral hydroureteronephrosis. Complete surgical excision was performed laparoscopically.
神经鞘瘤是起源于神经纤维施万细胞的良性肿瘤。它们通常发生在头颈部、纵隔和四肢。在骨盆中极为罕见。这些肿瘤通常生长缓慢，常为偶然发现。由于影像学上没有明确的征象，术前诊断极其困难。穿刺活检往往无法得出结论或产生误导。手术切除兼具诊断和治疗作用。由于这些肿瘤通常体积较大，最常采用开放切除。我们描述了一例巨大的盆腔囊性神经鞘瘤导致膀胱出口梗阻和双侧肾盂积水的病例。通过腹腔镜进行了完整的手术切除。
