title: A case of cerebral venous thrombosis as the presenting sign of occult prostate cancer.
abstract: BACKGROUND
  Cerebral venous thrombosis (CVT) is a distinct disorder with highly variable symptoms and courses. Malignancy is known to be one of the predisposing factors of CVT.
  
  
  METHODS
  We present the case of a 69-year-old man with sudden behavioral changes. Brain MRI, magnetic resonance venography, and positive D-dimer assay confirmed the presence of CVT. The work-up for detecting the cause of the CVT revealed occult prostate cancer.
  
  
  CONCLUSIONS
  Occult malignancy including prostate cancer should be strongly suspected in older patients with idiopathic CVT.
