18F-FDG PET/CT Imaging in Sarcomatoid Hepatocellular Carcinoma

Sarcomatoid hepatocellular carcinoma is a rare subtype of hepatocellular carcinoma. We present a 53-year-old man with a hepatic IV/VIII segment neoplasm whose tumor markers were all in the reference range. The neoplasm presented intense uptake of F-18-FDG and was confirmed as sarcomatoid hepatocellular carcinoma by immunohistochemistry. After 6 cycles of PD-1 treatment, no recurrence or metastasis was found by follow-up CT over 2 years. Thus, we reported a case of sarcomatoid hepatocellular carcinoma with complete remission to PD-1 treatment and provided some help for the diagnosis and treatment of sarcomatoid hepatocellular carcinoma.

Automated summary

In this article, we report a case of sarcomatoid hepatocellular carcinoma that achieved complete remission with PD-1 treatment, providing some assistance for the diagnosis and treatment of this rare subtype.
