Reverse Liver Spleen Uptake on [ 68 Ga]Ga-PSMA-11 PET/CT
Abstract
An 80-year-old man underwent [ 68 Ga]Ga-PSMA-11 PET/CT for staging of high-risk prostate cancer. Homogeneously increased liver uptake, more than 3-fold the splenic uptake, was seen. There was no hepatic lesion evident on CT. A higher liver to splenic uptake is more typical of some 18 F-labeled PSMA PET/CT but unusual in 68 Ga-labeled PSMA PET/CT scan. Further evaluation revealed a history of impaired renal function, bilateral renal atrophy, relatively decreased renal uptake of [ 68 Ga]Ga-PSMA-11, and prominent bowel activity. We concluded that impaired renal function and subsequent poor excretion resulted in increased hepatic excretion, hence the unusual increased homogeneous hepatic uptake.
