Bleeding sigmoid diverticulum

Case contributed by Dr Chris O'Donnell

Presentation

Multiple episodes of bright red, rectal bleeding

Patient Data

Age: 70 years
Gender: Female
CT

Sigmoid divertiular disease associated with a small area of luminal contrast extravasation on the arterial phase (arrow) that washes away on the delayed imaging.  This indicates active bleeding.

Case Discussion

CT angiography for rectal bleeding is only useful if performed whilst the patient is activley bleeding.  It is useful to do a 3 phase study to confirm that contrast leak on the arterial phase is not hyperdense faecal material and that it washes away on the delayed scan
