Case report. Inflammatory pseudotumor in the retrorectal space: CT and MR appearance

Abstract

We report a case of an inflammatory pseudotumor of the retrorectal space, with CT and MRI findings. The imaging findings in this case are consistent with those reported from other anatomic sites, demonstrating the aggressive nature of this histologically benign but frequently invasive mass. Recent discussions in the literature advise close imaging follow-up after surgical excision, particularly in cases in which incomplete resection is deemed preferable to a more mutilating radical resection.
