Introduction
CT perfusion is useful in acute ischaemic stroke to image cerebral tissue at risk (penumbra).1 However, perfusion changes are also common in people with ongoing epileptic seizures or postictal deficits (eg, Todd’s paresis).2 3 Although reduced or unchanged regional brain perfusion during ictal and postictal states is of little diagnostic help, hyperperfusion can suggest epileptic pathology. We report an illustrative case.
Case history
An elderly man was admitted with a suspected stroke. His wife had noticed subtle signs of confusion in him while shopping. When they …
