Fetal lymphangioma is also known as fetal lymphatic hydrocele or lymphocele. Studies have found that the main cause of the disease is the defect of fetal lymphatic system development, which leads to a large number of cysts in the neck (about 80%), axilla, groin and other parts of the body after the obstruction of local skin lymph reflux.
It should be noted that the perinatal mortality rate of fetuses with this disease is high (especially in the presence of chromosomal abnormalities, invasion of adjacent tissues, etc.), and the total mortality rate can be as high as 80-90% when accompanied by fetal edema.
Although the effect of oral sirolimus or sclerosing agent injection in the treatment of lymphangioma in infants and young children is worthy of affirmation, and some scholars have reported that a case of fetal cystic hyaline tumor was cured by abdominal injection in pregnant women, the treatment of fetal cystic lymphangioma is still very challenging.
Therefore, prospective parents must insist on 1/2 weeks of continuous prenatal color Doppler ultrasound assessment after discovering fetal lymphangioma (when lymphangioma affects the thoracic cavity, prenatal monitoring should be carried out once a week), and carefully choose according to the comprehensive opinions of obstetricians and gynecologists, newborns and infant hemangioma specialists.
