Name of the Patient : Abc Xyz Klmn / M / 40 yrs.
Referred by : Dr. Abc Xyzlsara.
Examination : M.R.I. of the Perianal Region.
CLINICAL PROFILE :
Patient has been operated for a perianal abscess in September 0000. At present has purulent discharge with blood.
M.R.I of the perianal region was performed using the following parameters:
8 mm thick T1 Weighted and T2 Weighted (with fat saturation) axial images.
6 mm thick STIR coronal images.
4 mm thick T1 Weighted and T2 Weighted (with fat saturation) coronal and sagittal images.
Irregularly defined areas of hypointensity on the T1 Weighted images which turn hyperintense on the STIR and T2 Weighted images are seen within the subcutaneous soft tissues adjacent to the anal cleft on either side. These are seen to extend upto the levator ani muscle at the level of the anal canal and distal rectum. The muscle at these levels is involved and irregularly defined. However the levator sling, anteriorly, is unremarkable.
The urinary bladder and prostate are unremarkable. The seminal vesicles are well visualized.
The MRI features are suggestive of areas of induration (with probable fistulas) along the anal cleft, on either side and extending upto the levator ani muscle as described.
