From the case:
Epiploic appendagitis
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/83158/annotated_viewer_json?lang=us"}
On CT this mass shows characteristic features:
- ovoid shape mass of fatty density (-60 HU)
- central hyperdense area dot, representing most likely the thrombosed vascular pedicle
- thin peripheral hyperdense rim (thickness = 2 mm)
- surrounding inflammatory fat stranding with thickening of the adjacent peritoneum
- located anterior to the descending colon
Case Discussion
Ultrasound and CT features are characteristic of an epiploic appendagitis
