Schwannomas are usually benign tumors that arise from the schwann cells in the neural sheaths of peripheral nerves. Most schwannomas occur in the head, neck, or limbs and rarely in the retroperitoneal space. In the retroperitoneal space, schwannomas are most commonly located near the adrenal gland. We report a successfully resected retroperitoneal benign schwannoma near the inferior vena cava (IVC) using laparoscopic surgery.
METHODS/RESULTS: A 33-year-old woman presented with dull abdominal pain for several months. Magnetic resonance imaging confirmed the existence of a round, sharply demarcated retroperitoneal solid tumor, 42 x 52 mm in size, located between the anterior of the right kidney and the IVC, which was compressed but still patent. The lesion was laparoscopically resected, and pathologic examination revealed a degenerative schwannoma.
Laparoscopic surgery is very useful and feasible in the diagnosis and treatment of retroperitoneal schwannoma, with minimal invasiveness and early postoperative recovery.
施万细胞瘤通常是起源于周围神经神经鞘中施万细胞的良性肿瘤。大多数施万细胞瘤发生在头、颈或四肢，很少发生在腹膜后间隙。在腹膜后间隙，施万细胞瘤最常位于肾上腺附近。我们报告了一例通过腹腔镜手术成功切除的下腔静脉（IVC）附近的腹膜后良性施万细胞瘤。
方法/结果：一名33岁女性因数月来的腹部隐痛就诊。磁共振成像证实存在一个圆形、边界清晰的腹膜后实性肿瘤，大小为42×52毫米，位于右肾前部和下腔静脉之间，下腔静脉受压但仍通畅。该病变通过腹腔镜手术切除，病理检查显示为退行性施万细胞瘤。
腹腔镜手术在腹膜后施万细胞瘤的诊断和治疗中非常有用且可行，具有微创性和术后恢复快的特点。
