Lymphatic malformations may be detected in the human fetus by ultrasound if they are of sufficient size. Detection of a<unk>  malformation may prompt further investigation, such as amniocentesis, to evaluate for genetic abnormalities in the fetus. Lymphatic malformations may be discovered postnatally or in older children/adults, and most commonly present as a mass or as an incidental finding during medical imaging. Verification of the diagnosis may require more testing, as multiple<unk>  masses can arise in children. Imaging, such as ultrasound or MRI, may provide more information as to the size and extent of the lesion.
