Conspicuity of cribriform prostate cancer on multiparametric magnetic resonance imaging: the jury is still out.

Cribriform, from the Latin for 'sieve-like,' describes an aggressive prostate cancer pattern associated with poor prognosis, including biochemical recurrence after prostatectomy [1]. Following progressive integration of multiparametric magnetic resonance imaging (mpMRI) into risk stratification for suspected prostate cancer, there has been understandable concern that particular morphologies (including, intraductal, mucinous and cribriform) may have reduced visibility on mpMRI [2]. If undetected, mpMRI-invisible pathology may avoid biopsy interrogation, resulting in delayed presentation, management, and adverse clinical outcome. However, evidence surrounding mpMRI conspicuity of cribriform disease is contradictory, and given the clinical importance of this phenomenon, warrants discussion.
