The Role of Lymphoscintigraphy in Diagnosis and Monitor the Response of Physiotherapeutic Technique in Congenital Lymphedema

We describe the case of a 4-month-old girl who was admitted for bilateral legs swelling for several weeks. Lymphoscintigraphy revealed the absence of the radiotracer proximal to the ilioinguinal nodes up to 6 hours postinjection. In light of the clinical and image findings, a diagnosis of congenital lymphedema was compatible. Systemic corticosteroid was given, and physical massage was applied at the lower extremities for 3 weeks. Repeat lymphoscintigraphy revealed faster lymphatic flow and liver visualization, demonstrating improvement in lymphatic function. This case illustrates the usefulness of lymphoscintigraphy in diagnosis and evaluating therapy response of lymphedema in children.
