Anorectal Abscess

Alternate Names : Perirectal Abscess, Perianal Abscess

How is the condition diagnosed?

Diagnosis of anorectal abscess begins with a medical history and physical exam. Diagnostic studies of the anus or rectum can determine the size of the abscess. This may include special X-ray tests, such as an MRI or ultrasound.

An anoscopy may be done to give the healthcare provider a direct look at the inside of the bowel. A special thin tube with a camera and light on the end of it is inserted into the anus and advanced into the bowel.
