In addition to squamous cell carcinoma, there are a variety of other less common malignancies and benign pathologies that may afflict the anal canal, with which abdominal radiologists should be familiar.

This review discusses these uncommon pathologies with a focus on their imaging appearance, management, and prognosis.
