A case report: 1-year follow-up of giant cystic lymphangioma of right mesocolon

Abstract Introduction: Cystic lymphangiomas are rare benign tumors of the lymph vessels and are usually found in children. However, abdominal cystic lymphangioma in mesocolon is extremely rare in adult patients. Case presentation: We reported a 15-year-old female with giant cystic lymphangioma of the right mesocolon. On examination, only abdominal pain was confirmed. Abdominal computed tomography (CT) showed a large multiseptated cystic mass. The patient underwent a total right mesocolic excision with the lesion. The patient recovered well on postoperative follow-up and was discharged on the fifth day. No evidence of recurrence had also been found during 1-year follow-up period. Conclusion: Complete tumor removal is the optimal choice for the management of intra-abdominal cystic lymphangioma. However, incomplete resection may lead to local recurrence.
