large intraluminal ileal hematoma presenting as small bowel obstruction in a child

intraluminal small bowel hematoma has been rarely reported in children, as a rare cause of small bowel obstruction. we present a case of an intraluminal ileal hematoma presenting as small bowel obstruction in a child. computed tomography (ct) indicated a large intraluminal hyperdense lesion in the distal ileum as the cause of small bowel obstruction. abdominal ultrasonography (us) showed an echogenic mass-like lesion with multiple septa in the distal ileum. small bowel obstruction due to a complicated cystic mass was provisionally diagnosed. histopathologic examination of the resected mass suggested a submucosal ileal hematoma. although intraluminal small bowel hematoma is rare in children, it can present as an intraluminal cystic mass and should be considered as a rare cause of small bowel obstruction. the us and ct findings of submucosal ileal hematoma could be useful for the diagnosis of such cases in the future.
