MRI of Epidural Cavernous IVlalformations of the Spine: Correlation with Surgical and Histopathologic Findings

Abstract

PURPOSE
The purpose of this study is to describe Magnetic Resonance(MR) findings of two epidural cavernous malformations of the spine.
MATERIALS AND METHODS
MR imaging was performed in 2 patients(29-year-old man and 54-year-old woman). Sagittal T1 -, T2-weighted images and Gadolinium (Gd)-enhanced axial and sagittal images were acquired. Two patients had surgery and MR findings were compared with surgical and histopathological findings.
RESULTS
MR imaging showed high- and low-signal intensity components of these lesions that were characteristic of an epidural cavernous malformation in one case. The other case showed a high signal intensity on T2- and strong enhancement on Gd-enhanced T1 -weighted images. We think that the former may be due to mixed subacute and chronic hemorrhage and the latter may be due to blood within the endotheliumlined sinusolds without hemorrhage.
CONCLUSION
These findings were well correlated with the surgical and histo-pathological findings of cavernous malformation.
