Prostatitis: imaging appearances and diagnostic considerations.

Clin Radiol 2021 Jun 22;76(6):416-426. Epub 2021 Feb 22.

Department of Radiology, Division of Abdominal Imaging, Massachusetts General Hospital, 55 Fruit Street, Boston, MA, 02114, USA.

Acute and chronic inflammation of the prostate gland can be attributed to several underlying aetiologies, including but not limited to, bacterial prostatitis, granulomatous prostatitis, and Immunoglobulin G4-related prostatitis. In this review, we provide an overview of the general imaging appearances of the different types of prostatitis, their distinguishing features and characteristic appearances at cross-sectional imaging. Common imaging pitfalls are presented and illustrated with examples. Read More

Comparative prostate MRI before and after chronic granulomatous prostatitis following intravesical bacillus Calmette-Guérin therapy.

Future Sci OA 2020 Oct 20;7(2):FSO637. Epub 2020 Oct 20.

Department of Urology, Saint Joseph Hospital, Beirut, Lebanon.

Background: Granulomatous prostatitis (GnP) is an interesting complication of bacillus Calmette-Guérin (BCG) therapy as it mimics prostate cancer on clinical, biochemical and imaging examinations. In the era of multiparametric prostate MRI (mpMRI), differentiation of GnP from prostate cancer on imaging is essential.

Case Presentation: We report a case of post-BCG GnP in a patient with nonmuscle invasive bladder cancer, presenting with a prostate-specific antigen level of 21. Read More

Varied Presentation of Fulminant Blastomycosis with Prostatitis and Acute Respiratory Distress Syndrome in a Patient With High Inoculum Inhalation: A Review of Diagnosis and Management.

Cureus 2020 Aug 12;12(8):e9686. Epub 2020 Aug 12.

Internal Medicine, SVS Medical College, Hyderabad, IND.

Blastomycosis is an uncommon granulomatous disease caused by infection with thermally dimorphic fungi of the genus Blastomyces. Although pulmonary infections from Blastomyces dermatitidis are uncommon, it is important to understand the geographical distribution, presentation, diagnosis, and management of treating this condition. We report a case of fulminant blastomycosis after high inoculum inhalation, with involvement of the prostate on presentation, which progressed to acute respiratory distress syndrome. Read More

Granulomatous prostatitis mimicking prostate cancer in a patient with psoriatic arthritis: a case report.

Future Sci OA 2020 Jun 17;6(7):FSO591. Epub 2020 Jun 17.

Department of Neuroscience, Reproductive Sciences & Odontostomatology, University of Naples Federico II, Naples, Italy.

Granulomatous prostatitis (GP) is an unusual and benign inflammatory condition of the prostate, where autoimmunity has been recognized as a key factor in the pathogenesis of GP in a subset of patients. Clinically, GP poses diagnostic challenges as it may strongly mimic prostate cancer from a clinical, biochemical and radiological point of view. The occurrence of GP in patients suffering from psoriasis, a systemic autoimmune disease, has never been investigated. Read More

Histopathology of nonspecific granulomatous prostatitis with special reference to eosinophilic epithelial metaplasia: Pathophysiologic, diagnostic and differential diagnostic correlations.

Indian J Pathol Microbiol 2020 Feb;63(Supplement):S34-S40

Department of Medical Biology, Medical University of Plovdiv; Technological Center for Emergency Medicine, Plovdiv, Bulgaria.

Background: Recently, we publish two case reports about association of nonspecific granulomatous prostatitis (NSGP) and eosinophilic metaplasia (EM) in benign prostatic epithelium. There is no investigation of large series of this association in medical literature. Aim of the current study is to investigate the frequency of association of NSGP and prostatic EM in a large series of cases and their relationship with the basic prostate pathology: benign prostatic hyperplasia (BPH), National Institutes of Health-category IV prostatitis (so-called histologic prostatitis (HP)), and prostatic adenocarcinoma (PCa).

Histologic findings associated with false-positive multiparametric magnetic resonance imaging performed for prostate cancer detection.

Hum Pathol 2019 01 1;83:159-165. Epub 2018 Sep 1.

Department of Urology, University of Alabama at Birmingham, Birmingham, AL 35249, USA; Department of Radiology, University of Alabama at Birmingham, Birmingham, AL 35249, USA.

Magnetic resonance imaging (MRI)/ultrasound fusion-targeted biopsy (TB) has been shown to more accurately identify higher-grade prostate cancers compared with standard-of-care systematic sextant prostate biopsy (SB). However, occasional false-positive imaging findings occur. We investigated the histologic findings associated with false-positive prostate MRI findings. Read More

The distribution of BCG prostatitis: A clue for pathogenetic processes?

Prostate 2018 11 10;78(15):1134-1139. Epub 2018 Jul 10.

Department of Histopathology, Norfolk and Waveney Cellular Pathology Service, The Cotman Centre, Norfolk and Norwich University Hospitals NHS Foundation Trust, Norwich, Norfolk, UK.

Background: We observed in cystoprostatectomy specimens that Bacillus Calmette-Guérin (BCG) granulomatous prostatitis tended preferentially to affect the peripheral zone (PZ) and aimed to study the matter, postulating that assessment of its distribution might contribute to understanding pathogenetic processes.

Methods: Entire prostate glands from 27 men (47-83 years; mean = 69 years), who had previously received intravesical BCG therapy for non-muscle-invasive urothelial carcinoma of the bladder, were studied as whole-mount sections to determine the anatomical distribution and histopathological characteristics of BCG prostatitis.

Int J Infect Dis 2018 Jul 17;72:63-68. Epub 2018 May 17.

Department of Infectious Diseases, Leiden University Medical Centre, Leiden, The Netherlands. Electronic address:

Intravesical bacillus Calmette-Guérin (BCG) is widely used for high-risk, non-muscle-invasive bladder cancer. This report describes four cases that illustrate the spectrum of BCG-induced complications, varying from granulomatous prostatitis to sepsis. There is considerable debate regarding whether inflammation or infection is the predominant mechanism in the pathogenesis of BCG disease. Read More

Treatment experience for incidentally diagnosed asymptomatic prostate tuberculosis in a patient with history of BCG intravesical therapy.

Urol Case Rep 2018 Mar 29;17:39-41. Epub 2017 Dec 29.

Department of Radiology in Trauma Center, Aju University School of Medicine, Suwon, South Korea.

Intravesical BCG therapy after transurethral resection of bladder tumor (TURB) is considered the most effective treatment for prophylaxis against the recurrence of high risk non-muscle invasive bladder cancer, and generally well tolerated and infectious complication are rare. We reported a case of granulomatous prostatitis is a patient who had undergone intravesical BCG therapy due to non-invasive superficial urothelial carcinoma of bladder. This patient was diagnosed by prostate biopsy because of PSA elevation without any other voiding symptoms and abnormal abscess pocket in transrectal ultrasonography. Read More
