RESUMO
We report a 57-year-old woman with optic-spinal form of active multiple sclerosis, who developed a large lobar type hemorrhage of the brain. She initially suffered from left visual loss, and three month later, she was hospitalized with paraplegia and total sensory loss up to the fourth thoracic level accompanied by sphincteric disturbance. Diagnosis of clinically probable multiple sclerosis was based on the relapsing-remitting clinical course and laboratory findings. Five months after admission, she developed sudden consciousness loss. Brain CT scan showed a massive hemorrhage in the right frontal to parietal lobe. The patient had no risk factors for cerebral hemorrhage including hypertension. Histopathological study of brain tissues obtained at surgical evacuation of hematoma did not reveal any malignancy, and congo-red staining of this specimen was negative. We analyzed coagulation, fibrinolytic, and endothelial parameters during the follow-up period. von Willebrand factor (vWF) as a marker for endothelial damages was elevated persistently. Moreover, thrombin-antithrombin III complex (TAT) as a marker for activation of coagulation was also elevated constantly throughout the clinical course. The findings suggest that fragility of the vascular walls and permeability changes associated with immunological mechanisms might have resulted in the cerebral hemorrhage. Although there are few reports of cerebral hemorrhage in patients with multiple sclerosis, it has been reported that vascular wall damage is an important aspect of the pathology of multiple sclerosis and acute cerebral vascular damage may sometimes occur in multiple sclerosis. We propose that coagulation studies including the endothelial marker such as vWF would provide a useful information regarding the risk of cerebrovascular complication in multiple sclerosis.
