- linear fistulous tract is seen oriented vertically, passing through the left side of the inter-sphincteric plane, starting superiorly from the level of the dentate line where it is seen abutting the internal sphincter at 1-2 o'clock position, and extending inferiorly to open into a marginally enhancing inflammatory fluid collection (abscess)
- the external sphincter is intact
- no definite side branches
Case Discussion
Surgically proved low type inter-sphincteric fistula.
The integrity of the external anal sphincter is crucial for the management's planning, also it is important to identify any side branches.
