Intra-sulcal punctate calcification may be related to prior hemorrhage or leptomeningeal calcifications. No acute cortical stroke is seen. If there is clinical concern for acute ischemia, MRI may be considered.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.
