Amiloidose Meníngea Difusa
Amiloidose • Deposição extracelular e acúmulo de proteínas e derivados de proteínas, com três elementos principais: componente amilóide P do soro (Serum amyloid P component), glicosaminoglicanas, e proteínas fibrilares. Os primeiros dois componentes estão presentes em todas as formas de amiloidoses, o último componente é variável e define o tipo de amiloidose. 1 • Há 15 tipos de proteínas fibrilares diferentes indentidicadas por análise imunohistoquímica e definem o tipo de amiloidose pela classificação da organização mundial da saúde. 2 http: //drugdiscoveryopinion. com/2009/07/first-disease -modifying-compound-targeting-protein-misfolding/
Amiloidose • Amiloidose envolvendo o sistema nervoso central pode se apresentar de maneiras diversas. A forma mais comum são depósitos amiloides em vasos arteriais levando a angiopatia amiloide ou angiopatia congofílica. O depósito destes materiais também pode levar a formação de placas senis na doença de Alzeimer. • Amiloidomas primários no sistema nervoso central são raros. Foram reportados 31 casos de amiloidomas no parênquima cerebral. 3 -32 e 8 casos comprometendo o gânglio de Gasser, sendo um deles com apresentação bilateral 33 -37.
