Mesenteric Lymphatic Malformation Causing Midgut Volvulus in an Adult: An Unusual Presentation

Abstract

Abstract Mesentery is an uncommon location for occurrence of lymphatic malformations. Lymphatic malformations causing midgut volvulus are described in pediatric population; however, it is a rare presentation in adults. We present case of 20-year-old man with a large mesenteric lymphatic malformation who presented with acute abdominal complaints. On radiological work up, the lymphatic malformation was seen causing midgut volvulus and closed loop small bowel obstruction with the presence of classical whirlpool sign. The patient underwent emergency surgery and the lymphatic malformation was completely excised along with resection of a segment of small bowel loop.
