Crohn’s Disease – Disappearing string sign
Terminal ileal disease is a common finding in Crohn’s Disease. Please take notice of the thin luminal bowel enhancement proximal to the cecum on the left image. On the right image, an abrupt cutoff can be appreciated (at lower centre of image) with fine “string-like” enhancement connecting the adjoining normal bowel. This is the string-sign associated with Crohn’s Disease and bowel spasm. [Courtesy of Dr. N. Jaffer]
