Insights
Gastrointestinal hemangiomatosis in infants, a rare cause of rectal bleeding, can be effectively treated with propranolol. This condition involves hemangiomas in the colon, leading to symptoms that resolve with medication.
Area of Science:
- Pediatric Gastroenterology
- Vascular Anomalies
- Medical Imaging
Background:
- Recurrent gastrointestinal hemorrhage in infants is a concerning symptom requiring thorough investigation.
- Intestinal hemangiomatosis, though rare, presents a diagnostic challenge in pediatric patients with bleeding.
Abstract:
A four-month-old girl presented with recurrent low gastrointestinal hemorrhage. Abdominal ultrasound showed diffuse parietal thickening and hyperemia of the colon. Computed tomography (CT) demonstrated diffuse thickening of the colon but also intense arterial globular mural enhancement with diffuse filling in the portal phase. Colonoscopy revealed multiple pseudopolipoid lesions along the colon which were histologically diagnosed as hemangiomas. The infant was diagnosed with gastrointestinal hemangiomatosis and was treated with propranolol resulting in complete resolution of symptoms.
Teaching Point:
Although rare, the possibility of intestinal hemangiomatosis should be considered in the setting of rectal bleeding in an infant.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
