History of Crohn's disease with a J-pouch excision presenting with deep perineal pain. PELVIS:PROSTATE/SEMINAL VESICLES: No significant abnormality noted.BLADDER: No significant abnormality noted.LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: Status post proctocolectomy. Interval J-pouch resection. In the resection/surgical bed there is a small amount of fluid measuring 2.8 x 1.9 cm (series 501/61) in maximal cross-section extending 10 cm in the craniocaudal dimension (series 901/27). On the sagittal images the fluid appears space-occupying without mass effect, however there is questionable peripheral rim enhancement on postcontrast imaging. No restricted diffusion or adjacent inflammatory changes to suggest inflammation/infection.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
Fluid in the proctectomy/surgical bed appears space-occupying without mass effect, however there is questionable peripheral rim enhancement on postcontrast imaging which may be surrounding peritoneal reflection enhancement as opposed to an organizing capsule. No restricted diffusion or adjacent inflammatory changes to specifically suggest inflammation/infection.
