Clinical question: Left-sided week less. Signs and symptoms: Left-sided weakness CT of brain without infusion:Very subtle questionable patchy areas of low attenuation in the cortex of the right insula and right frontal lobe may represent an early acute cortical stroke. There is no definitive mass effect with the above findings. The density of brain parenchyma is otherwise unremarkable. No evidence of hemorrhage is detected. Images through the posterior fossa demonstrate possible small old right cerebellar stroke and otherwise are unremarkable. Calvarium, paranasal sinuses and mastoid air cells are unremarkable.If clinical symptoms persist an MRI is recommended.
Only questionable cortical low-attenuation in the right insular cortex and frontal lobe as detailed.
