Mesenteric Cystic Lymphangioma “Intra-abdominal Catastrophe”

Lymphangioma is a benign tumour of lymphatic origin. Lymphangioma in peritoneal cavity is extremely rare (5%), particularly in adults. Hereby, we are reporting a case of a Malay gentleman with no co morbidity presented with sign and symptoms of intestinal obstruction. We proceeded with exploratory laparotomy with small bowel resection with primary anastomosis. Intraoperatively, revealed soft mesenteric mass measuring around 5X5 cm and it was 80 cm from duodenum-jejunum flexure. Histopathological examination showed mesenteric cystic lymphangioma (MCL). Cystic intra-abdominal mass should be included MCL as a diagnosis although it’s rare. Surgical management is still a mainstay of treatment due to its potential to invade vital structures and develop life threatening complication such as intestinal obstruction and bleeding. The surgical outcome after a complete clear margin resection can avoid recurrence.
