| Summary: | Arteriovenous malformation (AVM) is a lesion involving a high-flow vascular malformation,
which is one of the causes of massive gastrointestinal bleeding. In the pediatric
population, AVM is quite rare in the gastrointestinal tract, and the most common
primary site is the colon. A small bowel is a rare primary site of AVM, and only 1
case has been reported in Korea. Here, we report on a case of AVM found in the distal
ileum of a 14-year-old girl who complained about recurrent lower abdominal pain
only without a gastrointestinal hemorrhage. In the previous research literature, a small
bowel AVM can be diagnosed through detecting the existence of an enhancing nidus
of the intestinal wall at the arterial phase, accompanied by an early draining vein as it
appeared on a dynamic contrast-enhanced abdominal computed tomography. In our
case, the pathologically confirmed AVM of the distal ileum showed a dot-like enhancement
within the thick low-attenuating submucosal layer of the terminal ileum. |
