Prenatal diagnosis of limb and chest wall lymphangiomas

Fetal lymphangiomas are benign tumours that arise from abnormalities in the development of the lymphoid system. They mostly present on the neck and rarely appear on the limbs and chest wall (2-5%). We are reporting two cases of rare and isolated lymphangiomas diagnosed by prenatal ultrasound in the second and third trimesters. In both cases, adequate counselling, ultrasound surveillance until delivery and postnatal referral were provided. Prenatal diagnosis of lymphangiomas is essential to establish the prognosis, decide the route of delivery and guide a postnatal multidisciplinary approach.
