Prostate Cancer Pulmonary Metastasis Presenting as a Ground-Glass Pulmonary Nodule on 68Ga-PSMA-11 PET/CT.

ABSTRACT

Ga-prostate-specific membrane antigen 11 (PSMA) PET/CT imaging accurately depicts metastatic prostate adenocarcinoma (PCa). Pulmonary metastases of PCa are often overlooked on follow-up imaging in patients after initial treatment and following androgen deprivation therapy. Here we present a rare case of biopsy-proven PCa pulmonary metastasis with a ground-glass appearance. The increased PSMA expression and the evolving CT features of the solid component of the ground-glass nodule detected by PSMA PET/CT imaging led to surgical resection and PET/CT-guided therapy.
