This observation illustrates the use of CT in the diagnosis of rectosigmoid hemangiomas and the assessment of their extension. The CT appearance of hemangiomas is very specific and therefore allows confirming a diagnosis that is often difficult to make with other radiological techniques and with endoscopy: phleboliths within the thickened rectal wall are a characteristic sign. CT is primarily required when radical surgery is contemplated due to disabling repeated proctorrhagia: it provides a better delineation of trans- and extraparietal hemangioma extension, knowing that adhesion (...).
