Anterior mediastinal lymphangioma: Pre‐ and postnatal sonographic findings

Abstract

Anterior mediastinal lymphangiomas are very rare in utero with only a few cases reported in literature. We present a case of anterior mediastinal lymphangioma that was diagnosed on prenatal sonography (US) at 22 weeks' gestation. It appeared as a well-defined, multi-septated anechoic mass, in the anterior mediastinum between the heart base and right chest wall. There was no solid component and no internal flow on color Doppler US. The pre- and postnatal US findings are correlated with prenatal MRI and postnatal CT findings.

Vitamin K Deficiency Presenting in an Infant with an Anterior Mediastinal Mass: A Case Report and Review of the Literature

“…The most common of these are infantile lymphangiomas (formerly known as cystic hygromas) and kaposiform hemangioendotheliomas (KHE). Lymphangiomas are benign congenital malformations characterized by proliferation of normal lymphatic tissue and are frequently cystic in nature [ 22 ]. They are commonly diagnosed in children less than 2 years of age and most frequently arise in the head/neck or axillae; only 1-2% are found in the mediastinum.…”
