[Subarachnoidal Hemorrhage and Multiple Vascular Cerebral Abnormalities in β-thalassemia Major]

β-thalassemia is a genetic hemoglobinopathy, which can cause hypercoagulability, vessel wall damages and thromboembolic events. Spontaneous subarachnoidal hemorrhages are not commonly described in this affection. We report subarachnoidal hemorrhage, observed during the post-partum period in a 27-year-old woman suffering from β-thalassemia major. Brain MRI revealed complex vascular abnormalities: intracranial carotid occlusion, carotid micro-aneurisms, abnormally developed deep perforators and cortical arteries.
