A 23-year-old woman was admitted to our hospital with eosinophilic pneumonia. She developed left hemiparesis on the 3rd day of hospitalization, and magnetic resonance venography revealed superior sagittal sinus occlusion. She was diagnosed with cerebral venous thrombosis and treated with anticoagulant and steroid therapy. She developed acute subdural hematoma 7 days later and underwent emergency craniotomy and recovered without sequelae. Laboratory investigations revealed elevated eosinophils while the steroid was tapered; therefore, we diagnosed the patient with eosinophilia-induced cerebral venous thrombosis. Severe eosinophilia should be considered a risk factor for thrombosis.
