Prostate tuberculosis complicated by huge prostatic abscess: A rare case report from Nepal

Prostatic tuberculosis is one of the rarest findings in clinical practice and associated prostatic abscess is even scarce, described in literatures. We present a rare case of prostatic tuberculosis complicated by huge prostatic abscess.

A 68-year-old male with no any comorbidity presented with history of increased frequency of micturition along with poor flow, urgency and nocturia for 17 days. He was under medical treatment for benign enlargement of prostate for 2 years. Per rectal examination revealed a boggy cystic swelling anteriorly with enlarged prostate with mild tenderness. Ultrasonography abdomen and pelvis showed massive enlargement of prostate with central avascular necrotic area with moving internal echoes. Contrast enhanced computed tomography (CECT) showed 230 g of prostate with central liquefaction of approximately 101 mm³. Transurethral loop drainage along with resection of prostate was done. Histopathology revealed granulomatous prostatitis highly suggestive of prostatic tuberculosis. Prostatic abscess culture was negative. Patient is currently under category 1 anti-tubercular therapy.

Prostatic tuberculosis is a rare clinical finding which is commonly seen in patients with disseminated tuberculosis with immunocompromised status. Prostatic abscess in setting of granulomatous tuberculosis of prostate is even rarer. Transrectal ultrasonography is the investigation of choice for diagnosis of abscess if available. Treatment includes drainage of abscess preferably transurethral, and antitubercular therapy.

Trans-urethral loop drainage is a safe treatment modality for patients presenting with prostatic abscess followed by anti-tubercular therapy if histopathology findings are suggestive of granulomatous lesions.
