[Pseudotumoral cerebellar infarction of venous origin]

A case of venous thrombosis with pseudo-tumoral cerebellar infarction is reported. Cerebello-vestibular symptoms and intracranial hypertension had a progressive course over one and half month. CT showed an unilateral cerebellar lesion, with contrast medium enhancement and hydrocephaly. Thrombosis of the cerebellar superficial veins was found at surgical operation. A thrombosis of the transverse sinus was likely. No cause was discovered. This case, together with a published one, shows that a venous thrombosis may determine a cerebellar infarct.
