Atypical Todd's paralysis misdiagnosed as ischemic stroke:a case report
Abstract：Case: A male patient, 85 years old, presented with headache and limb weakness for 3 days without obvious cause. He was admitted due to sudden loss of consciousness accompanied by right-sided hemiplegia. He had a history of epilepsy for more than 10 years. Cranial MRI showed thickening and swelling of the left parieto-occipital cortex, with low signal on T1WI, mild high signal on T2WI and fluid-attenuated inversion recovery (FLAIR), and high signal on diffusion-weighted imaging (DWI), with reduced apparent diffusion coefficient (ADC) value (Figures 1A-E). These findings suggested an acute ischemic stroke in the left occipital cortex. After symptomatic treatment in the emergency department, the patient's limb weakness improved, and he was admitted for further treatment. On the first day of admission, the patient again experienced loss of consciousness, facial deviation, and delayed response with irrelevant answers.
