Clinical question: Evaluate for stroke. Signs and symptoms: Left-sided weakness, left facial droop. Nonenhanced CT of brain:No evidence of intracranial hemorrhage, edema, mass-effect, midline shift or hydrocephalus.Paucity of cortical sulci is within normal for patient stated age. Ventricular system, CSF cisterns and gray -- white matter differentiation remains within normal.Considering provided clinical data recommend further follow-up with an MRI examination since subtle findings of early acute stroke can be missed on non-infused head CT.Calvarium is intact.Visualized mastoid air cells and paranasal sinuses demonstrate extensive opacification.
1.No evidence of acute intracranial findings. Considering provided clinical data follow-up with an MRI is recommended to exclude early onset of acute stroke.2.Unremarkable CT examination of brain without contrast.3.Extensive opacification of visualized paranasal sinuses and mastoid air cells.
