Clinical question: Facial droop, rule out stroke. Signs and symptoms: Facial droop Not infused CT of brain:A subtle suspected low attenuation of cortex and subcortical white matter of the left inferior frontal lobe and possibly the operculum of left frontal lobe is noted. I cannot entirely rule out possibility of an artifact. Follow-up exam with an MRI is recommended if this finding could explain presenting symptoms. Provided clinical data is not detailed.This finding is notice on axial image 17 through 19.This examination is otherwise unremarkable. Cortical sulci, ventricular system and all CSF cisterns are within normal limits.Calvarium, paranasal sinuses, mastoid air cells and middle ear cavities are well visualized and unremarkable.
1.Suspected area of low-attenuation in the left frontal lobe may represent an ischemic stroke, possibility of an artifact in this case can not be entirely ruled out. Follow-up with an MRI is recommended.2.Negative CT of brain otherwise.
