title: [Rectal mucosa metastasis in recurrent prostate cancer : (68)Ga-PSMA-PET/CT allows targeted salvage radiotherapy].
abstract: This article presents for the first time a case of rectal mucosa metastasis of recurrent prostate cancer that was diagnosed with (68)Ga-PSMA PET/CT. After histological confirmation, the patient was treated with salvage radiotherapy. This case report underlines the specificity and efficacy of PSMA-based PET imaging. In case of biochemical relapse, it can be used even at low PSA levels to detect prostate cancer metastases that might also be in atypical locations. Thus, (68)Ga-PSMA PET/CT may allow new options for salvage therapy.
