Advanced Imaging Localizes Lesion & Rules Out Metastatic Disease
About 11 years after a diagnosis of prostate cancer treated with radiation therapy, a patient presented with progressively rising PSA levels. Multiparametric MRI revealed a lesion in the left medial posterior base peripheral zone; a subsequent MRI-ultrasound fusion biopsy demonstrated prostate cancer in 1 of 12 systematic cores and 3 of 3 targeted cores obtained from the lesion. An 18F-fluciclovine whole-body PET CT supported the conclusion of a local recurrence and found no evidence of metastatic disease.
