16 year old female with sickle cell disease. Headache. There is no evidence of intracranial hemorrhage, mass or edema. Slight prominence of the sulci in the right frontoparietal region and small areas of hypoattenuation in the right centrum semiovale are consistent with known prior strokes in this region as visualized on the MRI dated 4/1/2009. As with all CT findings of prior stroke, superimposed acute stroke cannot be entirely excluded.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.
Sulcal prominence and white matter hypoattenuation in the right frontoparietal region consistent with known prior stroke as detailed above.
