Fetal and Perinatal Lymhangiomas - A Spectrum of MR and CT Findings

Lympahgiomas are uncomon benign congenital multiloculated cystic malformations of lympahtics with the potential to infiltrate surrounding structures. They are discovered mainly by US, as first method of choice in fetal examination. However, fetal MR imaging is suitable to confirm or reject ultrasogographic findings, provides detailed anatomical orientation and is appropriate to evaluate the extent and character of lymphangiomas. This complementary technique contributes to the accurate diagnosis of lymphatic anomalies and benefits of excellent tissue resolution, large field-of-view and relative operator independency. This article present three cases of lymphangioma of different localizations, describes prenatal and perinatal magnetic resonance (MR) and computed tomography (CT) imaging findings, and discusses the advantages of those supplementary to ultrasound (US) methods in regard to patient counseling, management and delivery decisions /continuation or termination of pregnancy/
