68Ga-PSMA PET/CT Uptake in Cutis Verticis Gyrata

Abstract

68Ga–prostate-specific membrane antigen (PSMA) PET/CT scan for restaging revealed increased 68Ga-PSMA uptake in cutis verticis gyrata (CVG) in a patient with prostate cancer. Cutis verticis gyrata is an uncommon disorder in which the scalp thickens and mimics the cerebral cortex with deep grooves and folds. Several studies have demonstrated 68Ga-PSMA uptake in noncancerous conditions. This case illustrates another instance of a benign illness accompanied by increased 68Ga-PSMA uptake.
