Primary lymphangioma, lymphedema of the lower limb of the fetus in the practice of ultrasound

Abstract

Scientifically based and experimentally confirmed data on the morphogenesis of the lymphatic system are necessary to clarify critical periods of development characterized by an increased risk of congenital anomalies of the lymphatic system in order to plan and implement effective prevention, diagnosis and correction of related abnormalities. Among the studied anomalies of lymphatic vessels, lymphangioma is most often mentioned — a congenital benign tumor consisting of many cysts of various sizes. Detection of primary fetal lymphangioma in the early stages of intrauterine development is extremely rare. The purpose of the study: to report a case of early diagnosis of congenital cystic lymphangioma and lymphedema of the left lower limb of the fetus. Congenital (primary) peripheral lymphedema, limb lymphangioma is associated with a malformation of the lymphatic system. Taking into account the fact that operative methods of correction of all types of primary lymphedema are considered unreasonable and ineffective, the main attention requires timely detection of this congenital malformation during screening studies of the fetus and the issuance of recommendations for the management of pregnancy, up to termination for medical reasons. It is necessary to raise the issue of genetic counseling of the couple and conducting the necessary genetic studies. The use of modern diagnostic methods allows for the prevention and treatment of abnormalities in the development of the lymphatic system at an earlier stage of the intrauterine period.
