Multiparametric magnetic resonance imaging of the prostate (mpMRI) is a diagnostic tool used in the management of men with suspected prostate cancer. This modality provides valuable information regarding extraprostatic tissues and the prostate gland. This study aimed to identify incidental extraprostatic findings (IEPFs) in patients who underwent mpMRI.Methods: Data from patients who underwent mpMRI at our institution between October 2021 and September 2022 were retrospectively reviewed. Two experienced radiologists assessed the mpMRI scan images and reported using the Prostate Imaging Reporting and Data System (PI-RADS) categories. The findings were categorized as either related or unrelated to the genitourinary system. The findings were categorized into three groups: mild, moderate, and severe. A comparative analysis was performed to determine the clinical relationship between the PI-RADS score and age. Results: A total of 1000 scans were reviewed. A total of 29.4 % (n=294) of the patients had IEPFs. Fifty-one (5.1%) of these findings were related to the genitourinary system of the patient. Categorization based on the severity of the findings revealed that 333 patients had mild, 20 had moderate, and 13 had severe IEPFs. Analysis revealed a statistically significant difference in the distribution of genitourinary and non-genitourinary findings across groups (p < 0.001).Conclusion: As a diagnostic adjunct tool, mpMRI is not only valuable for aiding in the diagnosis of prostate cancer but also for the detection of IEPFs, the distribution of these findings differs significantly between genitourinary and non-genitourinary system, which may have important clinical implications.

Prostatın multiparametrik manyetik rezonans görüntülemesi (mpMRI), prostat kanseri şüphesi olan erkeklerin tanısal yönetiminde kullanılan bir tanı aracıdır. Bu yöntem, ekstraprostatik dokular ve prostat bezi hakkında değerli bilgiler sağlar. Bu çalışma, mpMRI ile değerlendirilen hastalarda rastlantısal ekstraprostatik bulguları (REPB) belirlemeyi amaçlamaktadır.Yöntemler: Ekim 2021 ile Eylül 2022 arasında kurumumuzda mpMRI'ye giren hastaların verileri retrospektif olarak incelendi. İki deneyimli radyolog, mpMRI tarama görüntülerini PI-RADS v2.1 kriterlerini kullanarak değerlendirdi. Bulgular, genitoüriner sistemle ilişkili veya ilişkili olmayan olarak kategorize edildi. Bulgular, hafif, orta ve şiddetli olmak üzere üç gruba ayrıldı.Sonuçlar: Toplam 1000 tarama incelendi. Hastaların yaklaşık %29'unda (n=294) REPB vardı. Bulguların elli biri (%5,1) genitoüriner sistemle ilgiliydi. Bulguların şiddetine göre kategorilendirme, 333 hastanın hafif, 20 hastanın orta ve 13 hastanın şiddetli REPB'ye sahip olduğunu ortaya koydu.Sonuç: mpMRI, prostat kanseri tanısı ve REPB tespiti için değerli bir yardımcı tanı aracıdır ve bazı durumlarda önemli olabilir.
