Other nontraumatic intracerebral hemorrhage [I61.8], Reason for Study: ^Reason: signs of vascular malformation or tumor History: history of right temporal lobe hemorrhage 2/2016 There is a susceptibility area with tissue loss on the right temporal lobe anterior aspect of the superior temporal gyrus indicating chronic hemorrhagic lesion. The area shows linear and somewhat nodular enhancement which could represent remained brain parenchyma. There is some curvilinear signal voids around the lesion which may represent vascular signal voids. There are also a couple of linear and nodular enhancing lesions around the area of encephalomalacia. Therefore, if clinically brain AVM is a possibility, diagnostic catheter angiogram should be considered.There is no evidence of acute ischemic lesion on the scan.The ventricles, sulci and cisterns are unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia. 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.
1. Chronic hemorrhage with encephalomalacia involving right anterior aspect of superior temporal gyrus.2. Multiple curvilinear signal voids around the area of encephalomalacia (right anterior temporal lobe) which may indicate possibility of underlying brain AVM. Therefore, if clinically indicated, diagnostic catheter angiogram can be considered.3. There is no evidence of acute ischemic lesion on the scan. There is no evidence of abnormal enhancement.
