Hemangioma of the small intestine manifesting as gastrointestinal bleeding.

Bleeding small bowel cavernous haemangioma following blunt trauma to the abdomen presenting as subacute intestinal obstruction in a child

“…The small intestine is the most common site of gastrointestinal haemangiomas, with the jejunum being the most commonly involved segment; haemangiomas represent approximately 7%–10% of all benign tumours of the small intestine 1. The colon is the second most common site of gastrointestinal haemangiomas; recto-sigmoid is the most commonly involved segment.…”

Beyond hepatic hemangiomas: the diverse appearances of gastrointestinal and genitourinary hemangiomas

“…Benign tumors of the gastrointestinal (GI) tract are rare, of which hemangiomas represent a small fraction, approximately 7% to 10% [37]. Hemangiomas may occur anywhere along the GI tract [38], and approximately 10% of patients have multiple GI lesions [39].…”

“…Hemangiomas can arise in any portion of the small bowel, but the mid jejunum is the most common location [37]. Some remain stable in size while others gradually enlarge.…”

“…Diffuse infiltrating tumors are usually solitary [41]. Most small bowel hemangiomas are symptomatic, unlike other organs, and may present with hemorrhage, abdominal pain, obstruction, intussusception, or rarely perforation [37,41,56]. Polypoid lesions usually become symptomatic during or after adolescence, while diffuse lesions can present as early as infancy [41].…”

“…On radiography, phleboliths may be seen. Barium studies can show nodular compressible filling defects originating from the wall when the lesions are large enough or diffuse luminal narrowing in diffuse hemangiomas [37]. On CT enterography, depending on size and type of involvement, hemangiomas may appear as discrete masses or polyps [58], or as diffuse wall thickening [56].…”
