In one patient (patient 4), no PCa was detected despite diffuse moderate tracer uptake on [18F]PSMA-1007 PET (SUVmax 8.7) and suspicious lesions on mpMRI (PiRADS 5); in this patient, 13 out of 24 needles had intermediate to high cpm ranging between 100 and 200 but only signs of inflammation at pathology, with 11/13 needles with confirmed PSMA expression on IHC. The gene discussed is FOLH1; the disease is posterior cortical atrophy.
