This investigation evaluates the accuracy of MRI fistulogram in diagnosing foreign bodies in perianal fistula, suggesting the need for additional imaging methods.
A BSTRACT Magnetic resonence imaging (MRI) is one of the common investigations in the case of perianal fistula. These patients commonly present with perianal pain, skin irritation, discharge, bowel incontinence, or fever. A fistula is suspected if the symptoms are recurrent. With the advancement in MRI techniques, there is improved spacial resolution picking up small lesions/openings and better tissue differentiation differentiating granulation tissue from abscesses. However, it has limitations in picking up unsuspected foreign bodies especially organic in nature (wooden in our case). In case of any suspicion, other modalities as USG and X-ray/CT scan can be used for better and accurate diagnosis.
