Abstract

To describe the imaging findings of prostatic tumors nonadenocarcinoma on multiparametric magnetic resonance imaging. A total of 200 patients underwented multiparametric magnetic resonance imaging of the prostate for screening for prostate cancer, from August 2013 to September 2014, followed by biopsy with ultrasound/magnetic resonance imaging fusion. We found three pathologic proved cases of prostatic pure leiomyomas (0.02%) in our series and described the multiparametric magnetic resonance imaging features of these prostatic leiomyomas. The imaging findings had similar features to lesions with moderate or high suspicion for significant cancer (Likert 4 or 5) when localized both in the transitional zone or in the peripheral zone of the gland. Pure prostatic leiomyomas had imaging findings on multiparametric magnetic resonance imaging that mimicked usual adenocarcinomas on this test. Radiologists, urologists and pathologists must be aware of this entity and its imaging features. Descrever os achados de imagem de tumores prostáticos não adenocarcinoma na ressonância magnética multiparamétrica. Realizaram ressonância magnética multiparamétrica da próstata para detecção de câncer de próstata 200 pacientes de agosto de 2013 a setembro de 2014, seguida por biópsia com fusão de imagens de ultrassonografia/ressonância magnética. Encontramos três casos confirmados histologicamente de leiomiomas prostáticos puros (0,02%) em nossa casuística e descrevemos os achados da ressonância magnética multiparamétrica destes casos de leiomiomas. Os achados de imagem foram semelhantes aos de lesões com moderada ou alta suspeição para neoplasia clinicamente significante (Likert 4 ou 5) quando localizados na zona de transição ou zona periférica da próstata. Leiomiomas puros da próstata tiveram achados de imagem na ressonância magnética multiparamétrica que mimetizaram adenocarcinomas. Radiologistas, urologistas e patologistas devem estar cientes destas entidades e seus achados de imagem.
