Case in brief

A patient with prostate cancer underwent 68 Ga-PSMA PET/CT, revealing a wedge-shaped area of increased PSMA uptake in segment VIII of the liver. MRI showed no focal lesion but indicated mild diffusion hyperintensity and transient arterial hyperenhancement. These imaging characteristics suggested a perfusion-related pseudolesion rather than metastasis, leading to a non-invasive management approach.

Diagnostic / clinical pearl

Clinicians should consider perfusion-related pseudolesions in the liver when interpreting 68 Ga-PSMA PET/CT findings, especially in the absence of corresponding MRI lesions.
