Mesenteric cystic lymphangioma – A rare case report; National Center for Pediatric Surgery, Gezira State, Sudan; 2021

Cystic lymphangioma is a benign congenital malformation of the lymphatic vessels. At the National Center for Pediatric Surgery, Gezira State, Sudan; 2021; a female baby of 15 months old age presented complaining of abdominal distention of 10 days duration. Patient Looks unwell, not febrile, and not pale or jaundice; abdomen was distended with full flanks, there was a palpable mass in the epigastric region, no area of tenderness and no palpable organs. Abdomino-pelvic U/S showed very huge abdomino –pelvic cystic mass with multiple thick septa. CT abdomen showed huge abdomino-pelvic mass with multiple cysts that having variable sizes measuring up to 6*7 cm. An elective explorative laparotomy was done. Intra operative findings: Multiple cystic masses arise from the root of the small bowel mesentery matted together with multiple enlarged mesenteric lymph nodes involving segment of distal jejunum with multiple adhesions. Release of adhesion, resection of the masses along with 57 cm of the involving jejunum, anastomosis was done, and homeostasis was secured. Histopathology result showed dilated cystic spaces; lined by flat endothelial cells and multiple reactive lymph nodes, no evidence of malignancy. Features are in line with lymphangioma and associated mesenteric lymphadenitis. Discussion and Conclusion: Our case was 15 months old which is the age of presentation as mentioned internationally. Mesenteric cystic Lymphangiomas are more common among male unlike our case. Ultrasonography and CT abdomen were highly recommended to achieve early diagnosis and treatment of such cases.
