A headache misunderstood for a grief reaction: an unusual cerebral venous thrombosis presentation.

This is a report of a 24-year-old woman who presented to the emergency department (ED) at Imam Hossein Hospital in Tehran, Iran with a one-week history of headache and agitation following her father's death. Before presenting to our ED, a diagnosis of conversion reaction was suggested by three physicians in different outpatient clinics. Cerebral venous thrombosis (CVT) was confirmed in this case on the basis of brain magnetic resonance imaging (MRI) and magnetic resonance venography (MRV). In this report, current knowledge regarding cerebral venous thrombosis and its related clinical features are discussed.
