Mesenteric cystic lymphangiomas (MCLs) are benign malformations of the lymphatic system that are most commonly diagnosed during childhood. The range of presentation varies with anatomic location. MCLs of the gastrointestinal tract can lead to bowel obstruction, and surgical intervention is warranted for those presenting in the acute setting. We report a case of a female neonate who was brought to the emergency department with a history of 24 hours of bilious emesis and abdominal distention. An abdominal X-ray was suspicious for bowel obstruction, and the patient was emergently taken to the operating room. A cystic lesion was identified in the mesentery of the jejunum, causing volvulus and bowel obstruction. The mass was resected, including the adjacent bowel. Pathology revealed a macrocystic lymphatic malformation (lymphangioma). The patient required total parenteral nutrition in the acute postoperative phase and has since weaned off successfully. The patient was ultimately discharged after an uneventful hospital course and was doing well at her 12-month follow-up. We concluded that MCLs are benign malformations that can be resected at the time of surgery. Due to the benign nature of these lesions, outcomes and prognosis are excellent.
肠系膜囊性淋巴管瘤（MCLs）是淋巴系统的良性畸形，最常在儿童期被诊断出来。其临床表现因解剖位置而异。胃肠道的MCLs可导致肠梗阻，对于急性发病的患者需要进行手术干预。我们报告一例女性新生儿，因有24小时胆汁性呕吐和腹胀病史被送至急诊科。腹部X线检查怀疑有肠梗阻，该患者被紧急送往手术室。在空肠系膜中发现一个囊性病变，导致肠扭转和肠梗阻。肿块被切除，包括相邻的肠段。病理显示为大囊型淋巴管畸形（淋巴管瘤）。患者在术后急性期需要全胃肠外营养，此后已成功停用。经过平稳的住院过程，患者最终出院，在12个月的随访中情况良好。我们得出结论，MCLs是良性畸形，可在手术时切除。由于这些病变的良性性质，结局和预后都很好。
