There is severe, extensive, abscess formation with associated soft tissue oedema affecting the base of the penis and scrotum, perineum, subcutaneous tissues of the buttocks, ischioanal fossa and ischiorectal fossa. Multiple complex tracts are seen.
There is no evidence of any significant supra elevator origin of the sepsis. Some involvement of the inter sphincteric plane is shown inferiorly. Low down in the anal canal a small tract crosses the external sphincter at 6 o'clock . The intersphincteric plane is also crossed slightly higher.
