Abstract

Purpose

Management of the unexplained AFP elevation after transplantation. F18 FDG PET/CT may not be helpful to detect post-transplant brain metastasis of hepatocellular carcinoma (HCC).

Case Report

A-61-year old male patient with HBV related HCC have undergone living donor liver transplantation after successfully downstaging. AFP level started to increase on Post-transplant one year and there was no detectable metastases on PET/CT, abdominal thorax tomography. Patient admitted to hospital with confusion and seizure on post-transplant 16th month and diagnosed brain metastasis by brain tomography. Surgical resection was performed but the patientd died on post-transplant 20th month.

Conclusion

In the unexplained elevation of AFP after transplantation, it is beneficial to keep brain metastases in mind and perform cranial scanning with conventional imaging methods (CT, MRI) rather than FDG PET.
