It has been known that the usual findings of SPECT in patients with Todd’s paralysis is the hypoperfusion of the cor-responding hemisphere. We experienced a patient who developed transient hemiparesis after a seizure attack with hyperperfusion rather than hypoperfusion over the corresponding hemisphere on brain SPECT. A 36-year-old female presented with left hemiparesis after a secondarily generalized tonic seizure. No additional seizure-like attack was noted during admission. EEG showed intermittent focal slow waves over the right frontotemporal area on admission and returned to a normal pattern 72 hours after admission. Tc-99m ECD SPECT showed hyperperfusion on the right fron-toparietal area in spite of the normalization of EEG. The degree of hyperperfusion was diminished as time passed for at least 72 hours. We report a patient who had Todd’s paralysis associated with contralateral frontoparietal hyperperfusion. Todd’s paralysis may be explained as the result of focal discharges that lead to local vasomotor changes.
