Neurilemmomas are benign tumors arising from the sheaths of peripheral nerves. They appear rarely in the abdominal cavity. We herein report an 80-year-old man with a multilocular cystic neurilemmoma mimicking a liver lesion. Preoperative images showed a lesion in the porta hepatis. Although a preoperative diagnosis was difficult, surgery was undertaken because of the possibility of malignancy. Histologically, the tumor consisted of spindle-shaped cells with positivity for S-100 protein. The final diagnosis was a neurilemmoma. Porta hepatic neurilemmomas are rare. When we encounter a multilocular cystic lesion of the liver, neurilemmoma should be considered in the differential diagnosis.
神经鞘瘤是起源于周围神经鞘膜的良性肿瘤。它们很少出现在腹腔内。我们在此报告一例80岁男性，患有模仿肝脏病变的多房囊性神经鞘瘤。术前影像显示肝门处有一个病变。尽管术前诊断困难，但由于存在恶性可能，仍进行了手术。组织学上，肿瘤由S-100蛋白阳性的梭形细胞组成。最终诊断为神经鞘瘤。肝门神经鞘瘤罕见。当我们遇到肝脏的多房囊性病变时，鉴别诊断应考虑神经鞘瘤。
