MRI Pelvis Fistula

Comparison: [].

Technique: Multiplanar T1 and T2, and after intravenous injection of [<17>] mL Magnevist, axial and coronal T1 fat saturation imaging of the pelvis was performed.

Findings: A linear band of enhancement extends from the skin surface in the left posterior perianal region. This can be traced cephalad through the external sphincter and into the intersphincteric region (series [<8>], images [<15>] through [<19>]). There is no evidence of rectal wall thickening or mass.
There are is no fluid collection to suggest abscess. No enlarged lymph nodes are evident. The prostate gland, seminal vesicles and bladder are unremarkable. Normal signal is noted in the bone marrow.

Impression: Left intersphincteric perianal fistula.
