Regional Cortical Hyperperfusion on Perfusion CT during Postictal Motor Deficit: A Case Report

Abstract

Postictal neurologic deficit is a well-known complication of focal or generalized seizures mimicking clinical manifestation of a stroke; however, it can be misdiagnosed as a stroke (1-3). Thus, in an acute setting, imaging studies are the most useful means for making the correct diagnosis (3). To our knowledge, there were a few reports of cortical hyperperfusion during postictal motor deficit in the literature. We report a patient who was presented with postictal right hemiparesis accompanied by perfusion and diffusion abnormalities in the left parietal cortical areas. Our case suggests that Todd’s paralysis may reveal transient perfusion and diffusion abnormalities; this report can be helpful for making an accurate diagnosis in patients with acute neurologic deficits.
