Giant Colonic Cavernous Hemangioma Causing Hematochezia in a 14-Year-Old Boy

A 14-year-old boy presented with intermittent hematochezia for 2 weeks. He reported a similar episode of hematochezia 1 year ago that was regarded as colitis. His medical history was unremarkable. Physical examination showed a nontender, soft, palpable mass at the upper right quadrant of the abdomen. His hemoglobin level was 7.3 g/dL (normal range, 13.0–16.0 g/dL). A computed tomography scan of his abdomen showed asymmetric segmental wall thickening with scattered punctuate calcification (Figure A, white arrow) and heterogeneous enhancement from the midtransverse colon to the hepatic flexure (Figure A, black arrow).
