Objective: Prostate tumors occasionally have unusual manifestations on multiparametric MR images that can present a diagnostic dilemma and result in a false-negative interpretation. This article presents examples of such "hiding places" of prostate tumors, four in the peripheral zone and four in the central gland.
Conclusion: The provided pointers in multiparametric MRI assessment can aid the radiologist in achieving an accurate diagnosis of tumor in the eight scenarios described.
