Leptomeningeal angiomatosis is an uncommon benign hamartomatous lesion usually involving the leptomeninges with or without cerebral cortex involvement.Three middle-aged patients with seizures from adulthood had undergone CT and MRI examinations and craniotomies which revealed leptomeningeal angiomatosis. Another two young patients with SturgeWeber syndrome and leptomeningeal angiomatosis were also evaluated.MRI is clearly helpful in establishing the topography and vascular malformative nature of the lesion, while CT is more accurate in detecting vascular calcifications.
L'angiomatosi cerebrale leptomeningeaStudio TC ed RM Riassunto -L'angiomatosi leptomeningea e una rara lesione amartomatosa benigna generalmente interessante le leptomeningi, con o senza coinvolgimento delta corteccia cerebrate.Tre pazienti di mezza eta con crisi epilettiche insorte in eta matura sono stati sottoposti a studio TC ed RM e successivamente a craniotomia, con il ritrovamento di angiomatosi leptomeningea. Sono stati studiati anche altri due casi, due giovani con sindrome di Struge-Weber associata ad angiomatosi leptomeningea.La tomografia e l'angiografia RM sono chiaramente utili nella definizione delta topografia e delta natura vascolare delle lesioni, mentre la tomografia computerizzata risulta piu accurata ne! riconoscimento delle calcificazioni vascolari.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
