Table 2 MRI Classification of Cavernous Malformations

From: Radiation-induced cavernous malformation after stereotactic radiosurgery for cavernous sinus meningioma: a case report

Lesion type

MRI characteristics

I

T1: hyperintense core,

T2: hyper- or hypointense core with surrounding hypointense rims

II

T1: reticulated mixed signal core

T2: reticulated mixed signal core with surrounding hypointense rim

III

T1: iso- or hypointense

T2: hypointense with a hypointense rim that magnifies the size of the lesion

GE: hypointense with greater magnification than T2 images

IV

T1: poorly seen or not visualized at all

T2: poorly seen or not visualized at all

GE: punctate hypointense lesions
