Case Report: High-grade anterior prostate cancer previously undetected by transrectal biopsy, diagnosed with MRI-US fusion transperineal robotic prostate biopsy.

Seventy percent of anterior prostate cancer cases are diagnosed during rebiopsy. MRI-US fusion transperineal robotic prostate biopsy is an emerging diagnostic method and might be an effective one in diagnosing prostate cancers in difficult sites such as the anterior zone. We report a case of a high grade anterior prostate cancer previously undetected by transrectal biopsy, diagnosed with MRI-US fusion transperineal robotic prostate biopsy. This case report suggests that MRI-US fusion transperineal robotic prostate biopsy might be valuable in diagnosing prostate cancer especially in difficult sites - the anterior region in this case - and might be an imperative diagnostic method in suspicious cases with prior negative biopsy.
