It is most often diagnosed in the head and neck of affected children. Rarely, a lymphangioma can develop within the small bowel (Pan Afr Med J. 2012;12:7). The clinical presentation of patients with an abdominal MCL can range from asymptomatic to acute abdominal pain (J Korean Surg Soc. 2012;83:102–106). We report a case of small bowel volvulus caused by an MCL in a 3-year-old child who presented to the pediatric emergency department with right lower quadrant pain. The child was thought to have a perforated appendicitis and was taken to the operating room where an MCL was identified and resected. This case illustrates the need to consider MCL when a patient presents to the emergency department with right lower quadrant pain.
