Unusual case of subarachnoid haemorrhage in patient with Fabry's disease: case report and literature review.

Fabry's disease is a rare, X linked recessive disease affecting 1 in 40 000 persons. The symptoms result from a lack of or a non-functioning enzyme α galactosidase, which leads to globotriaosylceramide accumulation in the walls of blood vessels. Mortality is generally from cardiac or renal complications and death from subarachnoid haemorrhage is distinctly rare. The authors report a man with Fabry's disease who died after subarachnoid haemorrhage from a progressively enlarging fusiform basilar aneurysm.
