Case series of perianal and pelvic MRI imaging findings in monkeypox.

Monkeypox is a viral infection historically rarely seen in humans, but currently the focus of international attention due to a multi-country outbreak outside endemic countries of Central and West Africa, where cases are typically confined. Perianal pain and lesions have recently been recognised as a feature of monkeypox. We present a case series of the imaging findings of patients with monkeypox, including active proctitis, anal canal inflammation, and perianal inflammation. The aim is to increase awareness of perianal and rectal monkeypox MRI imaging features during this current outbreak.
