In patients with cerebral venous thrombosis (CVT) the incidence of intracerebral hemorrhage (ICH) is estimated at about 37% and subarachnoid hemorrhage (SAH) at 1% of patients. A case with coincident occurrence of ICH, SAH and CVT in a patient with cerebral amyloid angiopathy (CAA) is reported.

A 79-year-old woman was admitted to the Neurological Department after the occurrence of generalized seizures, the first in her life. On admission she was unconscious with right hemiparesis and deviation of eyes to the left. On computed tomography (CT) scan many hemorrhagic infarcts were present in the frontal, parietal, temporal and left occipital lobes. Angio-CT revealed thrombosis in the right transverse sinus, right internal carotid vein and superior sagittal sinus. Her state slowly deteriorated. She died after 6 days. Neuropathologically, many hemorrhagic infarcts were observed in cortical regions in the vicinity of veins with thrombosis and in the white matter. The varied time of onset of thrombosis of the right sigmoid sinus, right superior petrosal sinus, superior sagittal sinus, right transverse sinus and the proximal part of the right internal carotid vein was confirmed. cerebral amyloid angiopathy in brain vessels was diagnosed.

Subarachnoid hemorrhage is a very uncommon presentation of CVT and may coexist with CAA. We can only speculate that CAA may have an effect on vein destruction and can promote cerebral vein thrombosis and in consequence also predispose to intracerebral hemorrhage and subarachnoid hemorrhage. The most probable cause of extensive thrombosis was a coagulation disorder.
