Diffuse cavernous haemangioma of colon: Magnetic resonance imaging features. Report of two cases

Abstract

Large bowel haemangiomas are rare but can cause significant morbidity. The clinical features are non-specific, and misdiagnosis is very common. Non-invasive imaging is very useful in the diagnosis and management of this condition. Magnetic resonance imaging surpasses all other imaging modalities, as it is most specific and depicts the extent of the lesion accurately. Two cases of cavernous haemangioma of the rectum are presented highlighting the MRI features.
