[1] When intestinal motility is impaired due to obstruction, progressive dehydration of luminal contents occurs, leading to the formation of solid particulate matter that mimics feces. [ 3 ]
Symptoms of AVMs vary according to their location. Most neurological AVMs produce few to no symptoms.Often the malformation is discovered as part of an autopsy or during treatment of an unrelated disorder (an "incidental finding"); in rare cases, its expansion or a micro-bleed from an AVM in the brain can cause epilepsy, neurological deficit, or pain.

Recently, multiphase CT angiography (without positive oral contrast) has been shown to play a promising role in the diagnoses of small and large bowel angiodysplasia ...
