Granulomatous prostatitis following bacillus Calmette-Guérin (BCG) immunotherapy is a well-known pathological entity, developing following initiation of BCG therapy as a prophylactic measure against the recurrence of non-muscle invasive bladder cancer. In addition, there are certain imaging similarities between granulomatous prostatitis and prostate cancer, including hypoechoic area on transrectal ultrasonography and low T2 signal intensity in some prostate areas on magnetic resonance imaging (MRI). This is the report of a case exhibiting a perfect imaging cross-match between granulomatous prostatitis and potential prostate cancer on repeated MRI exams, adding two supplementary aspects to the already known similarities, namely progressive restricted diffusion and increased contrast enhancement, which are specific to prostate cancer.

The aim of the study is to formulate an injectable nanocrystalline suspension (NS) of dutasteride (DTS), a hydrophobic 5α-reductase inhibitor used to treat benign prostatic hyperplasia and scalp hair loss, for parenteral long-acting delivery. A DTS-loaded NS (DTS-NS, 40 mg/mL DTS) was prepared using a lab-scale bead-milling technique. The optimized DTS-NS prepared using Tween 80 (0.

Article Synopsis
- - Granulomatous prostatitis (GP) is a rare type of chronic prostatitis, occurring in 0.65-1.5% of cases, and can show similar imaging characteristics to prostate cancer.
- - Key MRI features suggesting GP include low T2 signal, high diffusion-weighted imaging signals, and lesion enhancements post-contrast, particularly in cases with necrosis or abscesses.
- - A case study discusses a 70-year-old man with GP following treatment with intravesical bacillus Calmette-Guérin, highlighting the importance of biopsy for accurate diagnosis due to the imaging similarities with prostate adenocarcinoma.
Introduction: Xanthogranulomatous prostatitis is a very rare benign inflammatory lesion of the prostate that may be similar to prostatic carcinoma in clinical presentation and radiological characteristics.
Case Presentation: A 77-year-old man was admitted to our hospital because of high prostate-specific antigen level. Magnetic resonance imaging showed a 6.
Article Synopsis
- Granulomatous prostatitis (GP) is a rare, non-cancerous inflammation of the prostate that can mimic prostate cancer (PCa) during evaluations.
- The study analyzed 12 patients who developed GP after receiving BCG therapy for bladder cancer, focusing on their symptoms, MRI results, and tissue examination.
- Histopathological analysis is crucial to accurately diagnose GP, as it differentiates it from PCa by identifying granulomas, emphasizing the need for a combined clinical and imaging approach to prevent unnecessary treatments.
