False-positive mpMRI and true-negative ⁶⁸Ga-PSMA PET/CT xanthogranulomatous prostatitis: a case report.

ABSTRACT:

Background

Xanthogranulomatous prostatitis (XGP) is a rare disorder of the prostate. It presents as a hard fixed nodule on digital rectal examination (DRE), and may cause obstructive urinary symptoms and elevated serum prostate-specific antigen (PSA) levels, therefore mimicking prostate cancer (PCa) clinically and biochemically. Radiological features of XGP overlap with those of PCa, and the 2 conditions cannot be distinguished by pelvic multiparametric magnetic resonance imaging (mpMRI). ⁶⁸Ga-labelled prostate-specific membrane antigen (⁶⁸Ga-PSMA) with positron emission tomography/computed tomography (PET/CT) has shown its potential in the initial diagnosis and staging of PCa; however, the imaging characteristics of XGP on ⁶⁸Ga-PSMA PET/CT have yet
