Resection of an axillary macrocystic lymphatic malformation in a 14-year-old girl using intraoperative indocyanine green lymphography.

Lymphangioma is a malformation of the lymphatic system for which surgical excision is a possible treatment. However, complete excision may be hindered by the lesion's size, anatomic location, unclear borders, and invasion into adjacent tissues. We describe a 14-year-old girl who presented with a rapidly progressing axillary swelling. Magnetic resonance imaging and ultrasound revealed a lymphatic macrocystic multilocular lesion. After preoperative and intraoperative indocyanine green lymphography, a complete surgical excision was achieved without damage to collateral lymphatic channels or surrounding tissues. Intraoperative indocyanine green lymphography may be useful in achieving efficient and safe resection of lymphangioma without damaging unconnected lymphatics.
