Learning objectives: Evaluation of normal and benign pathologic conditions that could mimic a prostate carcinoma, seen in our department. Description of multiparametric magnetic resonance imaging (mp-MRI) features of these pitfalls and suggest strategies that can further their correct interpretation.

Background: A wide spectrum of conditions may mistake the interpretation of mp-MRI in the clinical practice. These enitities can be grouped in two categories: normal anatomic structures of prostate, that may be misinterpreted if their normal appearance is not recognized benign pathologic entities that may mimi[...]

Findings and procedure details: All mp-MRI examinations were performed on a 1,5 Tesla whole body scanner using a phased array body coil and endorectal coil. According to ESUR Guidelines, our protocol include sequences T2 weighted in the three orthogonal planes, Diffusion-Weighted Imaging (b-values 50-400-1200) and Dynamic Contrast[...]

Conclusion: A wide spectrum of normal and benign pathologic conditions mimic a prostate carcinoma. The knowledge of these pitfalls and their interpretation and recognition, differentiating from prostate carcinoma, can help radiologists to establish a correct diagnosis and management, avoiding misdiagn[...]
