Evaluate previously identified perianal abscess. PROSTATE/SEMINAL VESICLES: No significant abnormality noted.BLADDER: No significant abnormality noted.LYMPH NODES: Multiple bilateral inguinal prominent lymph nodes are unchanged from prior.BOWEL, MESENTERY: No significant abnormality noted.BONES/SOFT TISSUES: The previously identified left perianal soft tissue fluid collection is decreased in size (series 401, image 52), now measuring approximately 1.2 x 0.4 cm, previously 1.6 x 0.7 cm, with a perianal drainage catheter in place. This collection is hyperintense on T2 imaging, hypointense on T1 imaging and has restricted diffusion, compatible with abscess. Adjacent inflammation is identified on T2 imaging, which extends to the base of the left scrotum and minimally involves the right perineum. A right perianal drainage catheter is identified, with no associated drainable collection. No new fluid collection is identified.
Decreased size of the left perineal abscess and associated inflammation. Bilateral perianal drainage catheters are in place.
