69 year old male with history of lung cancer with metastases to the brain and thoracic spine. Patient had multiple new strokes recently. Rule out acute bleed or stroke. Curvilinear high density within the right subinsular cortex surrounded by low attenuation white matter corresponds to region of ischemia on MRI dated 11/5/2008 and likely represents dystrophic calcification within an area of chronic ischemia.There is no evidence of intracranial hemorrhage or edema. The ventricles and basal cisterns are normal in size and configuration.The calvaria and skull base are radiographically normal. The visualized paranasal sinuses and mastoid air cells are normally pneumatized.
No acute abnormality. Chronic ischemia within the right subinsular cortex with encephalomalacia and dystrophic calcification.
