A 21-year-old male presented with melaena and signs of hemorrhagic sho
ck. In the following days several episodes of hematochezia occurred re
quiring the transfusion of nine units of blood. Findings at gastroscop
y were normal, at colonoscopy fresh blood was noted from the ileocecal
valve. Angiography per formed in a bleeding-free interval showed no a
bnormalities. At repeat angiography, bleeding (from a left lateral bra
nch of the superior mesenteric artery) was provoked by instillation of
plasminogen activator. Subsequently, hemostasis was achieved by super
selective embolization using coils. At operation one week later, a pol
ypoid tumor of 1 cm diameter was resected along with a 4 cm segment of
adjacent jejunum (40 cm distal to the ligament of Treitz). Histologic
ally, a jejunal varix with superficial ulceration was diagnosed.
