Abstract

Schwannoma is a slow-growing benign tumor, which originates from Schwann cells and is usually asymptomatic. The most common sites of schwannomas are the head, neck, and extremities. However, a schwannoma located in the liver is extremely rare. Here, we report a 53-year-old woman with a hepatic lesion accidentally found by ultrasound. It was highly suggestive of hepatic cholangiocarcinoma by MRI. F-FDG PET/CT could not exclude hepatic malignant tumor due to its high metabolism. Finally, it was confirmed as hepatic schwannoma by postoperative pathology.

摘要

神经鞘瘤是一种生长缓慢的良性肿瘤，起源于施万细胞，通常无症状。神经鞘瘤最常见的部位是头部、颈部和四肢。然而，肝脏的神经鞘瘤极为罕见。在这里，我们报告了一位 53 岁女性，因超声偶然发现肝脏病变。MRI 高度提示肝内胆管细胞癌。由于其高代谢，F-FDG PET/CT 不能排除肝恶性肿瘤。最后，术后病理证实为肝神经鞘瘤。
