A Case of Perianal Fistula Mimicking Pilonidal Sinus
Abstract
A case of perianal fistula mimicking pilonidal sinus is presented. The fistula was diagnosed with magnetic resonance imaging (MRI) examination and confirmed with examination under anesthesia by retrograde manipulation of the probe at Morgagni crypts and continuity of the tract up to the external opening in in the sacrococcygeal region was confirmed. Tract of the fistula excised down to intergluteal cleft and the rest of the tract curetted. Patient was followed up to 3 months with complete healing of the fistula. In this unusual case we aimed to draw attention to rare presentation of perianal fistula with an external opening located as far as the sacrococcygeal region mimicking pilonidal sinus. Differentiating unusual presentation of perianal fistula from pilonidal disease sometimes is challenging.
