Giant congenital malformation of the perirectal plexus in computed tomography imaging - case report

Bartłomiej Kędzierski et al. Pol J Radiol. 2013 Apr.

Abstract

Background: Congenital arteriovenous malformation (AVM) in the pelvic area is uncommon in males.

Case report: The described case is of a giant lesion of this type that caused recurrent hemorrhaging in the lower part of the gastrointestinal tract. Preliminary diagnosis of vascular pathology was made on the basis of an endoscopic examination that revealed numerous pulsating protuberances of the rectal wall, in which blood flow was identified by means of transrectal ultrasonography. Complementing the diagnostics with a CT revealed a considerable extent of malformation, as well as its morphology and anatomical relations with the surrounding tissues.

Results: Following a two-year follow-up period, the malformation did not progress or demonstrate any intensification of clinical symptoms, therefore the patient continues to undergo conservative treatment.

Keywords: 3D reconstructions; Pelvic arteriovenous malformation (pAVM); computed tomography angiography (angio-CT); lower gastrointestinal tract bleeding; spiral computed tomography (CT).
