From: Challenges in the prenatal and post-natal diagnosis of mediastinal cystic hygroma: a case report
Contrast-enhanced computed tomography scan. Superiorly, this revealed a mixed attenuation, mainly cystic mass with a solid component within its left lateral aspect (arrow). More inferiorly, the lesion was of a more fluid density (arrowhead). These characteristics suggested a teratoma or congenital cystic adenomatoid malformation rather than cystic hygroma as the working diagnosis.
