Clinical question: Stroke. Signs and symptoms: Left-sided weakness. Nonenhanced CT of brain:There is diffuse low-attenuation of the left cerebellum along its inferior portion. I cannot be certain whether this represent a stroke or is artifact please correlate with history and physical exam and if there is worsening of neurological condition follow-up with an MRI is recommended. There is no evidence of hemorrhage. Right-sided pontine stroke shows no definite change. Fourth ventricle remains within normal size and in midline. No evidence of any significant mass effect in the posterior fossa. Images through supratentorial space are unremarkable.
1.No evidence of hemorrhage since prior study.2.Larger area of low attenuation in the inferior left cerebellum could represent an artifact however possibility of an additional stroke cannot be ruled out. Correlate with history and neurological exam and if there is deterioration follow-up with an MRI is recommended.
