A Case Treated by Dr. Monica Pearl
Lymphatic malformations are a type of low-flow congenital vascular malformation. First line of therapy for this type of lesion is percutaneous sclerotherapy. This baby was treated with a single sclerotherapy session with doxycycline at three months of age. Clinical and ultrasonographic follow-up at one year showed no recurrence.
Sagittal T2 and T1-post gadolinium weighted images show a T2 hyperintense, unilocular, peripherally enhancing left neck mass consistent with a macrocystic lymphatic malformation.
The lymphatic malformation is treated by percutaneous sclerotherapy, in which a small needle is placed into the lesion and a sclerosing agent is injected.
You can watch the video of the contrast injection here.
Clinical photograph 2 weeks after the procedure shows no visible mass. No residual lymphatic malformation was present at one year. The floppy skin overlying the left neck continues to involute.
