“…The role of MRI in preoperative staging of rectal cancer has been well established now. Though rectal cancer is the commonest cause of rectal mass, there are many other common and uncommon diseases which affect rectum and perirectal region, many of which can mimic rectal carcinoma and their distinction is essential as the management strategy changes significantly [1]. The objective of this review is to describe and illustrate the specific imaging findings of uncommon and atypical diseases affecting the anorectal region.…”

ObjectivesAlthough rectal cancer is by far and large the most common pathology involving the rectum that needs imaging, there are many other important but less common pathological conditions affecting anorectal region. The objective of this pictorial review is to discuss the cross-sectional imaging features of less common anorectal and perirectal diseases.ResultsAlthough a specific histological diagnosis cannot usually be made due to considerable overlap in the imaging appearances of anorectal diseases, this review illustrates the cross-sectional imaging findings with emphasis on magnetic resonance imaging (MRI) that can help in narrowing down the differentials to a reasonable extent.Teaching points• Variety of pathology exists in the anorectum apart from common rectal carcinoma• Anorectal diseases present as non-specific wall thickening indistinguishable from rectal carcinoma• Computed tomography (CT) and MRI can help in narrowing down the differentials, although often biopsy is warranted.

“…36,38 Gastrointestinal stromal tumour Gastrointestinal stromal tumour is the most common mesenchymal neoplasm of the gastrointestinal tract, most frequently seen in the stomach and small bowel, with rare occurrence in the anorectal region. 6 These neoplasms arise from the outer muscular layer and are typically exophytic. They may present with obstructing symptoms.…”

“…5 Tailgut cysts are often multiloculated cysts containing mucin and lack a muscular layer, a differentiating feature from rectal duplication cysts, which can be confirmed on endorectal ultrasound. [6][7][8] Up to 13% of these cysts may undergo malignant transformation, and for this reason, they are removed. 9 Rectal duplication cysts may be associated with other congenital abnormalities of the anorectal region and bladder/urethra.…”
