Abstract

Abstract : Abstract: 68 Gallium-prostate-specific membrane antigen ( 68 Ga-PSMA) is well established in the imaging of prostate cancer (PC). Here, we report a case of castration-resistant PC who underwent 68 Ga-PSMA PET/CT for recurrence evaluation, which revealed metastatic lesions in distant lymph nodes and additionally an unusual metastatic deposit in the inguinal canal. The second 68 Ga-PSMA PET/CT done after oral hormonal therapy yielded a favorable response. This pattern of distant metastatic spread is a rare presentation of PC, and PSMA PET/CT revealed the unusual metastasis in the inguinal canal with a timely therapy culminating in favorable disease response.
