Fanconi's anaemia and cerebrovascular anomaly.

Fanconi's anaemia (FA) is a paradigm of congenital anomalies including almost all systems. But FA with cerebrovascular anomalies is rare. The authors report a case of FA with hypoplasia of the posterior cerebral circulation including the basilar artery, bilateral vertebral arteries, posterior cerebral and posterior communicating arteries. The diagnosis of FA was established on the basis of induced chromosomal breakage study with mitomycin C.
