Histiocytic disorders encompass a group of rare diseases with a wide range of manifestations in which the abdominal involvement is quite infrequent. The role of the radiologist is to report the major imaging findings and the differential diagnosis; however, the imaging features are unspecific and biopsy usually is necessary to establish the definitive diagnosis.
Objective:To describe the imaging findings of prostatic tumors nonadenocarcinoma on multiparametric magnetic resonance imaging.Methods: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.Results: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.Conclusion: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.
Relato de caso J Bras Neurocirurg 21 (2): 122-125, 2010 Costa RO, Costa YB -Lipoma intradural extramedular sem disrafismo: Relato de caso e revisão da literatura RESUMO Lipomas medulares são tumorações benignas pouco freqüentes, sendo considerada rara sua ocorrência sem disrafismo vertebral associado. O surgimento das manifestações clínicas ocorre predominantemente por volta 2ª e 3ª década de vida, determinando, na maioria dos casos, um curso arrastado de deterioração neurológica que varia de acordo com sua localização. Descrevemos nesse relato um caso raro de lipoma medular intradural extramedular, sem associação com disrafismo; e fazemos uma breve revisão da literatura considerando a epidemiologia, tratamento e achados histológicos destas lesões. Palavras-chave: Lipoma medular, lipoma intradural extramedular, tratamento cirúrgico. ABSTRACTSpinal lipomas are infrequent benign tumors, its occurrence is considered rare when not associated with spinal dysraphism. The appearance of clinical manifestations occurs predominantly around the 2nd and 3rd decades, determining, in most cases, an insidious course of neurological deterioration that varies according to the lesion region. We describe a rare case of an intradural extramedullary lipoma, not associated with dysraphism; and we briefly review the literature considering the epidemiology, treatment and histology of these lesions.Relato de caso J Bras Neurocirurg 21 (2): 122-125, 2010Costa RO, Costa YB -Lipoma intradural extramedular sem disrafismo: Relato de caso e revisão da literatura
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
