title: [Cerebrovascular diseases in patients aged 15 to 40 years: neuropathological findings in 47 cases].
abstract: Cerebrovascular diseases in patients between 15 and 40 years old are not a frequent subject in Latin-American literature, especially when focusing on neuropathology. We analyzed 47 brains from necropsies performed from 1987 to 1997 and selected on a basis of age and the presence of vascular pathology. From the 47 analyzed brains, 26 belonged to females (55.3%). When distributed among age groups, 12.8% (n=6) affected patients from 15 to 20 yo, 51,1% (n=24) from 21 to 30 yo, 36,2% (n=17) from 31 to 40 yo. The underlying diseases were: cardiac and haemathologic (19.2%), pregnancy complications (12.76%), infections, diseases of blood vessels and neurological (10.1% each) amongst others. The neuropathological abnormalities included cerebral and/or cerebellar herniation (16%), cerebral edema (13.8%), subarachnoid hemorrhage (10%), recent cerebral infarction (9%), intraparenchymatous hemorrhage (8.14%), hypoxic-ischemic encephalopathy (3%) and other events such as Sneddon syndrome and Lupus vasculitis. These findings express that the cerebrovascular phenomena in this age group are unique and closely related with the underlying disease.
