The Teaching Point

Acute mesenteric ischaemia has a poor prognosis, partly due to delayed diagnosis and curative surgery; the close examination of unenhanced CT may aid rapid diagnosis and facilitate cure, as it can demonstrate an increased density in the tissue, which is lost with contrast enhancement.

Abstract
We present a 39-year old man with mesenteric ischaemia. The initial unenhanced images of the, non-oral contrast CT abdomen clearly demonstrated increased density in a significant length of the small bowel and in the veins of the adjacent mesentery. Mesenteric ischaemia is a difficult diagnosis both clinically and radiologically and we demonstrate the potential benefits of an unenhanced abdominal scan (often left out if a contrast enhanced scan is to be performed) and the omission of oral bowel contrast in emergency scans.
