Abstract

Objective: To discuss the clinical and MRI imaging characteristics of prostatic tuberculosis. Methods: From October 2008 to September 2017, 6 patients with suspicion of prostate cancer accepted prostate biopsy and diagnosed with prostatic tuberculosis by histology. The clinical features and pre-biopsy prostate multiple parametric MRI based on PI-RADS V2 were evaluated. Results: The mean age was 71.8 (range 58-79). No patients had systemic symptoms related to tuberculosis. Five cases had frequency and urgency. 1 case had history of BCG intravesicle instillation after diagnosed with bladder cancer. The mean PSA was 7.16(range 5.08 -10.34) ng/ml. Histologically, all the biopsy finds were confirmed as prostate tuberculosis. One-third showed micro-abscess. From imaging, 4 patients were regardless of malignancy, consideration of benign prostate hyperplasia and prostatitis (PI-RADS score ≤3). 2 patients were under suspicious of malignancy with PI-RADS score 4 and 5, suggested prostate biopsy.

Conclusion: Our initial experiences shows that if prostate MRI has complete capsule of prostate and low signal in DWI, it may help distinguish the asymptomatic prostatic tuberculosis with prostate cancer or benign prostate hyperplasia.
