摘要

Arachnoid cysts are benign, congenital malformations of the arachnoid. The mechanism of cystogen-esis remains unclear. In other diseases with cysts in various organs as a hallmark of the disease, such as autosomal dominant polycystic kidney disease (ADPKD), a genetic basis for the disease has been described. In ADPKD, arachnoid cysts have been reported to co-exist. The observations of familial occurrence of arachnoid cysts, in combination with the observed co-existence of arachnoid cysts and genetically determined cystic diseases, indicate a genetic component in the cystogenesis of at least some of the arachnoid cysts.
