Known cavernoma patient, follow-up. Headache, blurred vision No evidence of acute ischemic lesion on this scan.There is a lesion at the left parieto-temporal lobe trigone with susceptibility artifact consistent with cavernous malformation. The lesion appears to be located on the periventricular white matter with possibly the hemosiderin deposition on the left lateral ventricular wall. There is no evidence of associated DVA. There is no evidence of surrounding edema.There is no evidence of abnormal Gad enhancement.Above described findings do not show any significant interval change since prior exam. The ventricles, sulci and cisterns are symmetric and unremarkable. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
Re-demonstration of cavernous malformation on the left parieto-temporal lobe trigone area as described above. No change since prior exam.No evidence of new acute ischemic or hemorrhagic lesion on this scan.
