Anal cancer is a rare condition with several etiologic agents, including human papilloma virus (HPV) and other infectious agents. Oncogenes and carcinogens are also involved in anal cancer genesis. Among contributory factors are homosexuality with anal-receptive intercourse, immunosuppression, Crohn’s disease, and chronic anorectal disease. Staging systems, treatment regimens, and particularly indications for magnetic resonance imaging, are outlined in this chapter along with depictions of primary anal cancer and lymphatic spread and images documenting clinical response to chemoradiation.
