Neurilemmoma, also known as schwannoma or neurinoma, is a tumor that originates from neural sheath Schwann cells. Giant neurilemmomas derived from the retroperitoneum have rarely been reported. We herein describe a woman with a giant retroperitoneal neurilemmoma that was initially incorrectly diagnosed as an inflammatory abdominal mass. The tumor extended from the patient's hypogastrium to her pelvic cavity and measured 20 × 15 × 10 cm. The tumor was excised via laparotomy and diagnosed as a retroperitoneal neurilemmoma through histological and immunohistochemical examination. Although rare, particularly in the giant form, neurilemmoma should be considered as an important differential diagnosis in patients with a retroperitoneal tumor or inflammatory abdominal mass. Complete excision should be considered for the potential cure of giant retroperitoneal neurilemmomas.
神经鞘瘤，也称为施万细胞瘤或神经瘤，是一种起源于神经鞘雪旺细胞的肿瘤。源自腹膜后的巨大神经鞘瘤鲜有报道。我们在此描述一名患有巨大腹膜后神经鞘瘤的女性，该肿瘤最初被误诊为炎性腹部肿块。肿瘤从患者下腹部延伸至盆腔，大小为20×15×10厘米。通过剖腹手术切除肿瘤，并经组织学和免疫组化检查诊断为腹膜后神经鞘瘤。尽管神经鞘瘤罕见，尤其是巨大型，但在患有腹膜后肿瘤或炎性腹部肿块的患者中，应将其视为重要的鉴别诊断。对于巨大腹膜后神经鞘瘤，应考虑完整切除以实现潜在治愈。
