'Luxury perfusion syndrome' in a patient with reversible ischemic neurological deficits

A 28-year-old man was admitted to the hospital with difficulty in speech and motor weakness of the right arm of sudden onset. Twelve years previously a grade I oligodendroglioma had been removed. The CT scan showed a low density area without enhancement in the left frontal region that appeared to communicate with the left lateral ventricle. An increased flow through the left middle cerebral-artery and a focal avascular area in the left hemisphere was noted during a dynamic study by angioscintigraphy. A radionuclide cerebral control study showed reduced flow through the left middle cerebral artery. The patient was discharged 25 days after admission with the diagnosis of (1) reversible ischemic neurological deficits associated a hyperperfusion and (2) porencephaly.
