Estudo por ressonância magnética da região da pineal: pineal normal e cistos simples

Abstract: RESUMO -Realiza-se um estudo por ressonância magnética da pineal normal e dos cistos simples da pineal e estabelece-se um protocolo para estudo da região pineal analisando-se 762 exames. A utilização da técnica com cortes finos (3 milímetros no máximo) identifica a pineal normal na maioria das vezes (84,4%) e demonstra que a pineal normal, sem cistos, apresenta sinal isointenso em Tl e T2 com realce após a injeção de gadolínio, medindo em média 6,1 milímetros no seu maior diâmetro. Os cistos simples da pineal … Show more

“…The pineal region is defined as the space delimitated superiorly by the splenium of the corpus callosum and choroid plexus of the third ventricle, anteriorly by the third ventricle, antero-inferiorly by the lamina quadrigemina, inferiorly by the anterior face of the cerebellum culmen and laterally by the thalami and medial faces of the cerebral hemispheres 13 . The tumors of the pineal region are uncommon, ranging from 0.5 to 2% of all intracranial neoplasms in several review papers 3,5,6,14 .…”
