Other malformations of cerebral vessels [Q28.3], Reason for Study: ^Reason: 3 t scanner History: cavernoma Multiple fiducial markers attached on the scalp.There is brain parenchymal lesion with peripheral hemosiderin deposition with central T2 high signal intensity at the left inferior fronto-polar gyrus with slight extension toward left frontomarginal gyrus.The size is measured about 7mm on axial scan. Above findings are consistent with cavernous malformation, unchanged since prior scan.The ventricles, sulci and cisterns are unremarkable. The paranasal sinuses and mastoid air cells are clear.
1. Preoperative STEALTH scan.2. Left inferior fronto polar gyrus cavernous malformation is seen, unchanged since prior scan.
