Penile emergencies: a review of the main conditions

Abstract Acute penile conditions, which typically have a traumatic, vascular, or infectious etiology, are rather uncommon and often require prompt medical evaluation. Penile emergencies can be treated conservatively or surgically, and their management often relies on the results of imaging examinations. Because of its high spatial resolution and wide availability, as well as the fact that it does not involve the use of ionizing radiation, ultrasound is the imaging modality of choice in the initial evaluation of penile emergencies. Inconclusive cases can be further evaluated with magnetic resonance imaging. The main purpose of this pictorial essay is to review the main penile emergencies, by presenting illustrative cases, focusing on radiologic findings, and discussing the roles played by the various imaging methods.Resumo As condi ções agudas do pênis são raras, geralmente relacionadas a causas traumáticas, vasculares ou infecciosas, e muitas vezes requerem avaliação médica imediata. As emergências penianas podem ter tratamento conservador ou cirúrgico e muitas vezes dependem dos exames de imagem. A ultrassonografia é a modalidade de imagem de escolha na avaliação inicial das emergências penianas, em virtude da alta resolução espacial, ampla disponibilidade e ausência de radiação ionizante desse método. A ressonância magnética deve ser considerada em casos inconclusivos, oferecendo maior campo de v isão e detalhes precisos sobre o local e extensão das...
