Abstract
INTRODUCTION: Both small bowel intussusception in adults and small bowel hemangioma are rare benign mass lesions. Moreover, a secondary effect of intussusception caused by hemangioma is extremely rare. PATIENT CONCERNS: A 87-year-old female suffered from intussusception and intestinal obstruction caused by hemangioma located in the small bowel (February 14, 2020), reporting abdominal distention without nausea and vomiting. DIAGNOSIS: Emergency abdominal and pelvic computed tomography showed an intussusception with the evidence of associated small bowel obstruction. Histological analysis revealed as small intestinal hemangioma accompanied by mesenteric ulcer. INTERVENTIONS: The patient underwent segmental resection of intussusception of intestine instead of invalid conservative treatment. OUTCOMES: Although the postoperative pathological results were inconsistent with preoperative imaging examination, the old woman recovered well. CONCLUSION: The literature on intussusception of small intestine has described several possible causes including hemangioma, which more likely results in gastrointestinal bleeding or abdominal pain. Yet we experienced a rare case presenting as abdominal distention without nausea and vomiting, Therefore, preoperative diagnosis and localization of these lesions is of great importance. We recommend high resolution contrast-enhanced computed tomography and magnetic resonance imaging should be considered in diagnosis while capsule endoscopy is not available owing to the intestinal obstruction, as long as in facilitating surgical excision.
