Extensive loculated fluid collection encircling the rectosigmoid and anal canal with surrounding inflammation suggestive of an anorectal abscess.
The abscess is extending from supralevator regions bilaterally to intersphincteric region. A complex fistulous tract is advancing from the left intersphincteric abscess to the subcutaneous region on the left side at 4-5 o'clock position in relation to the anal opening, less than 5 mm from the skin surface suggestive of an impending fistula.
The abscess is causing significant rectal and anal luminal compromise.
