"the lesion is complex and contains cystic and solid areas. The cystic areas elicit fluid density and represent the lymphatic component of the lesion while the solid areas appear hyperdense to brain parenchyma on non-contrast CT and represent the venous component of the lesion."
"intralesional phleboliths are occasionally seen and appear as small dense foci within the solid venous part of the lesion."
"T1: iso- to hyperintense to brain parenchyma"
"T2: hyperintense to brain parenchyma with occasional multiple fluid-fluid levels"
"T1 C+ (Gd): marginal and septal enhancement of the cystic spaces with a variable enhancement of the solid components"
"The term lymphangioma is outdated (as per ISSVA 2018 classification). Be aware that newer research reference the term orbital lymphatic malformation."
