All that Glitters on PSMA is Not a Lesion: An Unusual Artifact on PSMA PET/CT

Indraja D Dev et al. Indian J Nucl Med. 2021 Jul-Sep.

Abstract

Nonspecific uptake of prostate-specific membrane antigen (PSMA) on PSMA positron-emission tomography/computed tomography (CT) is normally encountered in benign conditions, which is detected on morphological changes on CT component. However, having a site of uptake without any CT finding is a rare occurrence. We herewith report one such rare case of a 66-year-old male with metastatic prostatic adenocarcinoma, who demonstrated an incidental finding of intense focal PSMA uptake in the lung parenchyma.

Keywords: Iatrogenic; prostate-specific membrane antigen; pulmonary embolism.

Maximum projection intensity (a) image shows intense focus of uptake in the right lung region, which corresponds to focal prostate-specific membrane antigen uptake on axial and coronal fused positron-emission tomography/computed tomography images (b and c); however, no morphological lesion is seen on axial and coronal computed tomography images (d and e) in lung window
