RESUMO
Cerebral hyperperfusion syndrome is a major cause of morbidity and mortality following carotid artery stenting (CAS). We present a case of acute subdural hematoma (SDH) 2 hours after CAS. In this case, arterial origin of bleeding was verified during operation. To our knowledge, there is no prior case report of SDH without intraparenchymal nor subarachnoid hemorrhage subsequent to CAS. We postulate that SDH was caused by sudden rise in intracranial pressure due to the hyperperfusion which disrupted a corticodural bridging artery.

A 69-year-old male admitted to the psychological department due to delusion. One week later, he developed pneumonia and deep drowsy mental status. Despite improvement of pneumonia, his mental status got worse and he was referred to neurological department. The complete blood count tests showed repeated hypereosinophilia. The serologic tests revealed toxocariasis. He was treated with steroid and albendazole and his mental state rapidly improved. Toxocariasis is a common cause of reactive hypereosinophilia, which may be an underestimated etiology of reversible encephalopathy.
