MR imaging of the retrorectal–presacral tumors: an algorithmic approach

Authors: Hooman Hosseini-Nik, Keyanoosh Hosseinzadeh, Rajesh Bhayana, Kartik S. Jhaveri

Published in: Abdominal Radiology | Issue 7/2015

Abstract

The retrorectal–presacral space is located posterior to the mesorectum and anterior to the sacrum, and can harbor a heterogeneous group of uncommon masses. Retrorectal–presacral tumors may be classified as congenital, neurogenic, osseous, and miscellaneous. Magnetic resonance imaging (MRI) plays a crucial role in directing appropriate management through accurate diagnosis, detection of complications and anatomic extent. MRI aids in the selection of optimal surgical approach such as anterior, posterior, or combined—based on the lesion extent and relationship to adjacent structures. This article reviews the anatomy of the retrorectal–presacral space and the related tumors, optimal MRI protocol, MRI-based approach to differential diagnosis, and finally pertinent reporting pointers and implications of MR imaging findings for surgical management.
