Case Discussion
Nowadays, surgeons will send almost all patients with perianal fistula for a pelvic MRI before the operation, as it reduces the recurrence rate. This patient had surgery and the feedback from the surgeon was the same as our report. There is no fluid in the tract but there is enhancement, the interpretation is that there is granulation tissue but no pus.
