ABSTRACT

Hyperintensity at diffusion weighted magnetic resonance imaging (DWI) and hipointensity at ‘apparent diffusion coefficient’ (ADC) mapping are indicators of cytotoxic edema. These changes are typical for acute ischemic cerebrovascular accidents. During epileptic seizures, transient imaging findigs can be seen in the cranial computed tomography and magnetic resonance imaging. MRI studies during partial status epilepticus in animals show DWI and ADC anomalies which can be related to cytotoxic oedema. Same findings can also be seen in humans. Migraine and transient ischemic attacks can cause transient changes in the MRI which may also accompany epileptic seizures. We discuss here a 44 years old patient who had sensorial complaints and weakness after new onset migraine -like headache accompanied by transient MRI findings.
