Definition / general
  • Rare single or multiple benign vascular tumors, often in ileum and mid jejunum
  • Either diffuse, circumscribed or papillary growths
  • May cause anemia, hemorrhage, intussusception, melena, obstruction, perforation (Zhonghua Bing Li Xue Za Zhi 2005;34:275)
  • May be associated with hemangiomas elsewhere
Types of hemangiomas
  • Capillary: usually asymptomatic, small, solitary, composed of tightly packed capillaries
  • Cavernous: localized or diffuse; blood filled sinuses with minimal connective tissue; often symptoms of a mass or bleeding
  • Arteriovenous: most common type; abnormal veins and arteries but otherwise resembles cavernous hemangioma
