A huge mesenteric lymphangioma of the jejunal mesentery resulting in failure to thrive

Mesenteric lymphangiomas are rare in occurrence. The dumb-bell shaped ones are even rarer. We report a case of a 7-year-old girl with a huge dumb-bell shaped mesenteric tumor weighing 3 kg, located in the jejunal mesentery and causing failure to thrive. En mass excision of the tumor along with the involved bowel segment was done with a successful outcome. Histopathology diagnosed the tumor to be mesenteric lymphangioma of the jejunal mesentery. At a follow-up of 2 years, the child is symptom-free and has a good catch up growth.
