Widespread involvement of hepatic, renal and mesenteric arteries with multiple mycotic aneurysms in a child

Multiple visceral microaneurysms of mycotic origin are very uncommon. We present an 11-year-old child with the clinical and biochemical signs of septicemia in whom arteriographic study revealed multiple microaneurysms of renal, hepatic, gastroduodenal, ileocolic and right colic arteries. Six weeks of antibacterial treatment resulted in resolution of the septicemia and most of the aneurysms healed without the need for endovascular or surgical treatment.
