Hepatic Schwannoma on 18F-FDG PET/CT

Clin Nucl Med. 2020 Oct;45(10):808-810. doi: 10.1097/RLU.0000000000003159.

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.
