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 m idtransverse colon to the hepatic flexure (Figure A, black arrow).
