Conclusions: Sclerotherapy is an effective first-line therapy for intra-abdominal LMs in the pediatric population and should be considered when treating these difficult lesions.

Methods: We conducted a retrospective review from 2008 to 2012 of all children with intra-abdominal LMs treated with sclerotherapy at our tertiary children's hospital.
