Solitary nerve sheath tumors can arise in peripheral, cranial, or sympathetic nerves at virtually any anatomic site. Although origin along the nerves of the retroperitoneal space is not uncommon, these tumors rarely present as pelvic masses. We describe two patients found to have benign nerve sheath tumors of the sacral plexus. Neurilemomas (schwannomas) and neurofibromas are thought to result from a proliferation of perineural cells. These tumors are characteristically firm, smooth, and asymptomatic. They range in size from 1-2 mm to over 20 cm. Surgical excision can usually be accomplished by enucleation of the tumor without damage to the adjacent nerve. Resection of sacral plexus tumors requires knowledge of pelvic retroperitoneal anatomy to avoid injuries to the nearby vascular and urinary structures.
孤立性神经鞘瘤几乎可发生于周围神经、颅神经或交感神经的任何解剖部位。虽然起源于腹膜后间隙的神经并不罕见，但这些肿瘤很少表现为盆腔肿块。我们描述了两名被发现患有骶丛良性神经鞘瘤的患者。神经鞘瘤（施万细胞瘤）和神经纤维瘤被认为是由神经周细胞增殖引起的。这些肿瘤的特点是质地坚硬、表面光滑且无症状。其大小从1 - 2毫米到超过20厘米不等。手术切除通常可通过肿瘤剜除术完成，而不会损伤相邻神经。骶丛肿瘤的切除需要了解盆腔腹膜后解剖结构，以避免损伤附近的血管和泌尿结构。
