Abstrakt:	Introduction and Importance: Chylolymphatic cysts are benign pathology in lymphatic vessels due to obstruction in the lymphatic system. Their incidence is still unknown. However, they account for approximately 3 % to 9 % of all pediatric lymphangiomas. Most of these lesions are asymptomatic and are discovered accidentally. They can present with non-specific abdominal pain, vomiting and changes in bowel habits. Rarely, Chylolymphatic cysts can cause fatal complications such as intestinal obstruction, volvulus or even torsion. Case Presentation: A 3-month-old male presented to our unit with manifestations of acute intestinal obstruction. Abdominal examination revealed signs of generalized peritonitis and intestinal obstruction. Abdominal ultrasound revealed minimal turbid intraperitoneal collections and no motility of bowel loops. Plain erect abdominal radiograph revealed multiple small bowel air fluid levels. Abdominal exploration revealed a large Chylolymphatic cyst causing acute intestinal obstruction. Excision of the cysts was done with preservation of adjacent bowel loop. The patient was discharged in good health on the 6th day postoperative. A chylolymphatic cyst with a diameter of 5 cm was identified by histological investigation. Clinical Discussion: Mesenteric cyst is a rare intra-abdominal tumor with prevalence of about 1: 20,000 in pediatric age group. They are benign cystic pathology lined with a thin endothelium or mesothelium occur due to gross proliferation of isolated or ectopic lymphatics in mesentery that lack communication with the rest of the lymphatic system. Regarding pathology, mesenteric cysts are classified into four types including type 1 (Pedicled) and type 2 (Sessile), which are limited to the mesentery, hence can be excised completely with or without resection of the involved gut. Type 3 and type 4 are multicentric, so they require complex surgery and often sclerotherapy because of their extension into retroperitoneum. The majority of mesenteric cysts may present as asymptomatic abdominal mass or incidental finding on imaging or during laparotomy for other abdominal conditions. Preoperative diagnosis of mesenteric cyst in most cases is difficult as they have no definite characteristic features. Abdominal ultrasound which is the imaging modality of choice can reveal mesenteric cysts as cystic tumors. Surgical removal of the cyst is the standard treatment for chylolymphatic cysts. Conclusion: Most Chylolymphatic cysts in infants are asymptomatic, but they can cause fatal complications such as intestinal obstruction, volvulus or even torsion.
