Abstract

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.
