A ressonância magnética deve ser considerada em casos inconclusivos, oferecendo maior campo de visão e detalhes precisos sobre o local e extensão das lesões. 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. As emergências penianas podem ter tratamento conservador ou cirúrgico e muitas vezes dependem dos exames de imagem. 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.Īs condições agudas do pênis são raras, geralmente relacionadas a causas traumáticas, vasculares ou infecciosas, e muitas vezes requerem avaliação médica imediata. Inconclusive cases can be further evaluated with magnetic resonance imaging. 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. Penile emergencies can be treated conservatively or surgically, and their management often relies on the results of imaging examinations.

#Penile fracture imaging serial
These serial findings may suggest the formation of vascularised granulation tissue during cicatrisation.
Then the tear site gradually recovered low signal intensity on all spin-echo sequences by 4 months after surgery. Shortly after the repair, the tunical suture showed an increase in signal intensity on pre-contrast T1WI and was strongly enhanced with the administration of contrast material. On follow-up MRI all fractures presented similar healing process. Concomitant subcutaneous haematoma were well visualised both on T1-weighted (T1WI) and T2-weighted images, whereas haematoma in CC were optimally demonstrated on contrast-enhanced T1WI.
In all patients pre-contrast T1-weighted images (T1WI) clearly disclosed ruptures of CC, which depicted as discontinuity of low signal intensity of the tunica albuginea (TA). In three patients, follow-up MRI was also available at 1, 6 and 16 weeks after surgical repair. Imaging findings were confirmed at surgery. Four patients with clinically suspected acute penile fractures underwent MRI. The present study describes the role of MRI for diagnosis and follow-up of this injury. A rupture of corpus cavernosum (CC) is a rare injury of the erect penis.
