A case report of a mesenteric cystic lymphangioma in a young adult woman presenting to the emergency room.

Background: Mesenteric cystic lymphangiomas (MCLs) are rare benign tumours seen in adults. The clinical presentation may vary from asymptomatic to acute abdominal pain with inexplicable abdominal pain, nausea and vomiting.

Case presentation: In the current case report, a 22-year old, healthy women presented to the emergency room with acute abdominal pain in need of urgent surgical exploration. Histopathological examination revealed an mesenteric cystic lymphangioma.

Conclusion: In patients with inexplicable abdominal pain, the suspicion of MCLs and proper diagnostic strategies are important. The primary treatment of MCLs consists of radical surgical resection to prevent invasion in surrounding tissue. Tertiary referral centres should be consulted to support in the diagnosis, treatment and follow-up of MCLs.
