MRI IN ISOLATED TRANS-SPHINCTERIC FISTULA IN ANO OPENING NEAR SCROTUM-A VERY RARE ENTITY: 2 CASE REPORTS

Abstract

Bhimarao1, Rashmi M. Nagaraju2

Fistula in ano is an inflammatory condition affecting perianal region and adjacent structures. It is a cause of significant morbidity, requiring repeated surgical treatments due to its high recurrence rate. Most perianal fistulous disease have external openings located within 2.5 cm of the anal verge. It is rare for an anal fistula to involve the scrotum. Such involvement can occur frequently in patients with inflammatory bowel disease, especially Crohn’s disease and rarely in ulcerative colitis. Isolated involvement of scrotal region is quite rare without concomitant inflammatory bowel disease. This has been rarely reported in the literature. We present 2 isolated cases of trans sphincteric fistula in ano with external opening in the vicinity of scrotum. Both our cases did not reveal any signs of inflammatory bowel disease.
