Lymphoscintigraphy patterns in newborns and children with congenital lymphatic dysplasia.

We performed lymphoscintigraphy on 31 patients (newborns and children) affected by congenital lymphatic dysplasia according to our previously published protocol. Congenital lymphatic dysplasia may present with various degrees of clinical severity, ranging from nonimmune hydrops fetalis with visceral effusions to lymphedema alone. We recommend that lymphoscintigraphy should be strongly considered in all patients with signs of lymphatic dysplasia, including those with minimal and initial signs of lymphatic impairment, in order to obtain a very early diagnosis and to start treatment. Lymphoscintigraphy is safe and useful in the diagnosis of lymphatic dysplasia in the newborn and children. Moreover, it is well tolerated by patients and well accepted by their parents.
