Single-site laparoscopic excision of mesocolic cystic lymphangioma - a video vignette

Unusual acute right abdominal pain. Distal ileum mesenteric cystic lymphangioma in adult, a rare case and literature review

Lymphangiomas in the peritoneal cavity are rare in adults, with most cases occurring in children. We present the case of a 49-year-old woman who was admitted with severe lower abdominal pain. The diagnostic assessment revealed a multiloculated cystic structure in the mesentery of the distal ileum, suggesting a lymphangioma. The patient underwent laparotomy and resection, with successful removal of the mass. Histopathological examination confirmed the diagnosis of intestinal lymphangioma, a rare benign vascular neoplasm of the small bowel. Postoperatively, the patient experienced resolution of postoperative ileus and mild back and abdominal pain, with no complaints during follow-up. Awareness of this uncommon condition is crucial for accurate diagnosis and appropriate treatment. Surgical resection, supported by radiological and histopathological investigations, is the primary treatment modality for symptomatic lymphangioma. Regular follow-up with imaging may be necessary to monitor recurrence.

Case report: A mesocolic lymphangioma in a 14-year-old child resected by laparoscopic surgery

Introduction

Cystic lymphangioma is a benign malformation tumor of the lymphatic system. Its location is variable, and mesocolic localization remains extremely rare.

Case presentation

We report a case of right mesocolon giant cystic lymphangioma in a previously healthy 14-year-old boy who was successfully managed through a minimally invasive laparoscopic excision. The patient presented with 8 months of dull abdominal pain, sporadic, located on the peri-umbilicus, exacerbated for a month. An abdominal computed tomography (CT) revealed a large, multiseptated cystic mass on the right mesocolon. Right mesocolic excision using a laparoscope was performed on this patient. He was discharged on the fifth day without complications. Recurrence was not detected in three months of follow-up.

Conclusion

Cystic lymphangiomas in the mesocolon are rare benign neoplasms that pose diagnostic challenges. Complete resection is the optimal option for diagnostic confirmation and recurrence prevention. Laparoscopic surgery is feasible for children with mesocolic lymphangioma.
