| Abstract in Portuguese | O diagnóstico e as condutas terapêuticas nos tumores intrínsecos do tronco encefálico, sofreram grandes
transformações com o advento da tomografia computadorizada e da ressonância nuclear magnética. Estes métodos
diagnósticos permitiram a identificação de diferentes subgrupos de tumores da região, alguns dos quais passíveis de
extirpação cirúrgica, com sobrevida prolongada e eventual cura. Os autores apresentam dois casos de um peculiar
grupo de rumores do tectum do mesencéfalo, cujos aspectos tomográficos e manifestações clínicas sugeriam estenose
do aqueduto de Sylvius de início tardio. O diagnóstico definitivo foi estabelecido por RNM. Em ambos, os sintomas
desapareceram após instalação de derivação ventricular. As características clínico-patológicas e as alternativas
terapêuticas deste subgrupo particular de tumores do tronco encefálico são discutidas. | pt_BR |

| Abstract | The introduction of computerized tomography and magnetic resonance imaging led to the knowledge
that brain stem tumors are not a homogeneous group with regard to their clinical, pathological and biological features.
The classical concept of an uniformly poor prognosis has been modified and some subtypes of tumors are amenable
to surgical treatment and long-term survival. The authors report two cases of patients with tumors of the tectal region
whose symptoms and CT features were consistent with late-onset aqueductal obstruction. In both cases definitive
diagnosis was established by MRI and symptoms resolved after ventriculo-peritoneal shunt implantation. The clinic
and pathological features and therapeutical alternatives as well, are discussed. | pt_BR |
