Abstract
Mesenteric cysts are uncommon entities and chyle- (lymph-) containing cysts are the rarest of this group. This is a case report of a 4-year-old boy with a mesenteric chylous cyst who was later found to have Histoplasma capsulatum infection.
Highlights
Chylous cysts are benign proliferations of lymph vessels which result from an obstruction in the lymphatic system
These lesions can present with symptoms such as abdominal pain, nausea, vomiting, anorexia, and changes in bowel habits; most commonly they are asymptomatic and are detected incidentally on physical exam or imaging
On Exploratory Laparotomy, we found a very large (15 cm in diameter) mesenteric cyst within the small bowel mesentery located 30 cm from the ileocecal junction and obstructing a portion (10 cm) of small bowel lying above it (Figures 1, 2, and 3)
Summary
Chylous cysts are benign proliferations of lymph vessels which result from an obstruction in the lymphatic system. They account for approximately 3% to 9.2% of all paediatric lymphangiomas, their incidence is unknown [1, 2]. These lesions can present with symptoms such as abdominal pain, nausea, vomiting, anorexia, and changes in bowel habits; most commonly they are asymptomatic and are detected incidentally on physical exam or imaging. Most mesenteric cysts are benign, these lesions occasionally cause complications, including intestinal obstruction, volvulus, or even torsion [3, 4]
