ABSTRACT
Squamous cell carcinoma of the esophagus is endemic in Rio Grande do Sul, the most southern state of Brazil, where the incidence reaches 27 out of 100,000 inhabitants per year. Palliative treatments, surgical or nonsurgical, impose lower mortality and lower costs. The choice of the best treatment for each patient depends on the neoplasia staging, and the local involvement of the tracheobronchial tree by tumor characterizes incurability. Computed axial tomography (CAT) is indicated, but remarkable contradictions were found in the literature. We studied 134 patients, diagnosed with esophageal squamous cell carcinoma, who underwent computed tomography and fiberoptic bronchoscopy (gold standard) performed with an uniform technique. An accuracy of 85.1% was obtained when computed tomography was compared with bronchoscopy with regard to impingement, displacement and invasion of trachea and bronchi. In conclusion, there is no statistically significant difference between computed tomography and fiberoptic bronchoscopy in the evaluation of tracheobronchial involvement by squamous cell carcinoma of the esophagus (p < 0.05).

Os autores relatam um caso de mixoma de ventriculo direito acompanhado por discretas lesoes mixomatosas em atrio esquerdo.As manifestacoes clinicas encontradas foram semelhantes as dos demais casos de mixoma de ventriculo direito publicados na literatura, sendo as mais importantes:quadro clinico semelhante ao da estenose pulmonar; presenca de ecos multiplos em ventriculo direito; existencia de gradiente pressorico entre ventriculo direito e arteria pulmonar; presenca de defeitos de enchimento no infundibulo ventricular direito, evertendo para a arteria pulmonar a angiocardiografia. Foi realizada cirurgia cardiaca com pleno sucesso, tendo-se encontrado um volumoso mixoma de ventriculo direito e discretas lesoes mixomatosas em atrio esquerdo. O diagnostico de mixoma foi confirmado por exame anatomopatologico
