Perianal abscess

Case contributed by Dr Mehmet Yağtu


Pain around the anal region especially during defecation and sitting. Intermittent fever.

Patient Data

Age: 40 years
Gender: Male

There is a large collection which located in the bilateral ischioanal fossae and has one large track extending intersphincteric space at six o' clock forming the "horseshoe" pattern. Although the abscess reaches to levator base, it is not extending to the supralevator space, best seen on the sagittal images. The border of the collection and surrounding fatty tissue are contrast-enhancing because of inflammation.

Case Discussion

Anorectal abscesses are an infective-inflammatory collection within the perianal region. They develop from infection and anal gland drainage obstruction and often associated with perianal fistulae. But our patient had no fistulae clinically.
