A 45 year-old patient presented with an epidermoid carcinoma of the to
ngue and cranial hypertension. MRI showed dural venous sinus occlusion
, without infiltration or compression by a metastatic tumor. Anticoagu
lation led to recanalization of the occluded sinuses, as shown by the
follow-up MRI, three months later. The pathophysiology of these rare p
araneoplastic cerebral venous thrombosis is discussed.
