Nontraumatic intracerebral hemorrhage, intraventricular Abnormal electroencephalogram (EEG) The myelination pattern is appropriate for patient's age. The corpus callosum is thin. There is mild prominence of the extra-axial subarachnoid spaces. The gray-white matter differential aeration is preserved. The left lateral ventricle remains asymmetrically enlarged, similar to prior examination No areas of diffusion abnormality are identified. There is no evidence for acute intracranial hemorrhage. Susceptibility artifact from hemosiderin deposition is demonstrated within the lateral ventricles. There is no midline shift or mass effect.
Stable asymmetric enlargement of the left lateral ventricle, prominence of the subarachnoid spaces, and thinning of the corpus callosum without evidence for acute abnormality.
