Abstract
Neurological complications resulting from pronounced cerebrovascular changes were observed in a 59-year-old female suffering from Grönblad-Strandberg syndrome. In addition to typical skin changes of the pseudoxanthoma elasticum and ocular alterations (exudative macular degeneration and angioid streaks) there were an unusual number of disturbed endocrinological functions. The ophthalmological findings revealed characteristic breaks in Bruch's membrane, proliferation of chorioidal vessels into the subretinal space, hyperplasia of retinal pigment epithelium and disciform macular degeneration. Postmortem examination of the brain showed multiple cerebral infarcts due to recurrent disturbances in cerebral blood supply and particularly pronounced changes in the elastica interna of many cerebral arteries. Although the observed neurological signs in our patient were not characteristic of Grönblad-Strandberg syndrome, the histopathological findings led to the assumption that the same basic mechanisms result in alternations of elastic fibres and collagen, mainly in the ocular-cerebral system.
