Renal Pelvis Metastasis From Prostatic Adenocarcinoma Missed by PSMA PET: A Case Report

摘要

Metastasis of prostate cancer to renal pelvis is extremely rare. A 64-year-old man was hospitalized for increased prostate-specific antigen after radical prostatectomy. Ga-68-PSMA-11 PET/CT showed hydronephrosis caused by a mass in the left renal pelvis without significant uptake of prostate-specific membrane antigen tracer. The histopathology indicated metastatic prostate cancer with a Gleason score of 5 + 5 but negative for prostate-specific membrane antigen following nephroureterectomy. Although metastasis to renal pelvis is rare, the occurrence possibility could not be ignored when with hydronephrosis is found in prostate cancer patients. (C) 2019 Elsevier Inc.
