Acute cerebrovascular insults in homozygous beta-thalassaemia: a case report.
Neurological complications following vascular thrombotic crises are frequent and occur in sickle cell anaemia and its variants, but are less well recognized in thalassaemias. A case of beta-thalassaemia major is reported complicated by an ischaemic lesion involving the right cerebellar hemisphere. The probable pathogenesis is considered and the literature on the matter briefly reviewed. In agreement with other reports, the interference of risk factors provided by or occurring in association with multiple blood-transfusions is hypothesized. Consequently, caution is recommended in giving large blood-transfusions to thalassaemic patients.
