Pelvic and bilateral symetric lower extremities involvement of extensive fetal cystic lymphangioma: A case report

Extensive fetal cystic lymphangioma is a rare congenital malformation of the lymphatic system. Their prognosis depends on the size and location of the lesions as well as other accompanying anomalies. Our case was 35 years, fetal BPD was 27 weeks. Herein, we present a case of extensive fetal cystic lymphangioma that began at the pelvic area and symmetrically spanned the bilateral proximal and distal lower extremities. Numerous extensive and sharply circumscribed, thin walled multilobular cystic lesions in different sizes were observed in the subcutaneous superficial and deep soft tissue beginning from the pelvic area and extending to both lower extremities to the distal in the fetüs. To our knowledge, a case involving both extremities has not yet been reported in the literature.
