CT Abdomen & Pelvis – 9

CT ABDOMEN WITH CONTRAST AND CT PELVIS WITH CONTRAST

REASON FOR EXAM: Generalized abdominal pain with swelling at the site of the ileostomy.

TECHNIQUE: Axial CT images of the abdomen and pelvis were obtained utilizing 100 mL of Isovue-300.

CT ABDOMEN: The liver, spleen, pancreas, adrenal glands, and kidneys are unremarkable. Punctate calcifications in the gallbladder lumen likely represent a gallstone.

CT PELVIS: Postsurgical changes of a left lower quadrant ileostomy are again seen. There is no evidence for an obstruction. A partial colectomy and diverting ileostomy is seen within the right lower quadrant. The previously seen 3.4 cm subcutaneous fluid collection has resolved. Within the left lower quadrant, a 3.4 cm x 2.5 cm loculated fluid collection has not significantly changed. This is adjacent to the anastomosis site and a pelvic abscess cannot be excluded. No obstruction is seen. The appendix is not clearly visualized. The urinary bladder is unremarkable.

IMPRESSION:
1. Resolution of the previously seen subcutaneous fluid collection.
2. Left pelvic 3.4 cm fluid collection has not significantly changed in size or appearance. These findings may be due to a pelvic abscess.
3. Right lower quadrant ileostomy has not significantly changed.
4. Cholelithiasis.
