a axial T2 WI, b STIR WI and c coronal STIR WI for a linear inter-sphincteric track of intermediate/high signal in T2/STIR WI touching the internal sphincter at 4–5 O’ clock. Axial DTI/T2 fused images with ROI (FA and ADC) values placed in d the inter-sphincteric track, e ipsilateral and contralateral sphincters and f surrounding edema area with FA values 0.852, 0.778, and 0.833 and 0.723 with ADC values 0.188,0.553, 0.278 and 0.711 × 103 mm2/s, respectively. The FA and ADC values are relatively high indicating inactive inflammatory condition
