Case in brief
A 7-year-old boy presented with abdominal pain and vomiting, ultimately diagnosed with small bowel volvulus via abdominal ultrasound and contrast-enhanced CT showing the whirlpool sign. Emergency surgery revealed an 8 cm multilocular cyst in the mesentery, causing volvulus. A partial small bowel resection and cystectomy were performed, confirming mesenteric lymphangioma through pathological examination.
Diagnostic / clinical pearl
Clinicians should consider mesenteric lymphangioma in pediatric patients presenting with abdominal symptoms, especially when conservative management fails, as it can lead to serious complications like volvulus.
