ABSTRACT

O carcinoma bronquíolo-alveolar e os adenocarcinomas mistos com componente bronquíolo-alveolar têm apresentações variadas e múltiplos padrões por imagem. O objetivo deste ensaio foi descrever e ilustrar os achados mais característicos desses tumores em TC. São descritas três apresentações: nódulo pulmonar solitário, consolidação e apresentação difusa, sendo que as duas últimas são importantes no diagnóstico diferencial com acometimento infeccioso. O conhecimento das diversas apresentações e a utilização de propedêutica diagnóstica adequada são definitivos para o diagnóstico precoce e o aumento na sobrevida.


Bronchioloalveolar carcinoma has various presentations and a wide spectrum of imaging patterns, as does adenocarcinoma with a bronchioloalveolar component. The objective of this essay was to describe and illustrate the CT findings that are most characteristic of these tumors. Three presentations are described: solitary pulmonary nodule, consolidation, and diffuse pattern. The last two should be included in the differential diagnosis, together with infectious diseases. Knowledge of the various presentations and the use of proper diagnostic procedures are crucial to early diagnosis and to improving survival.

ABSTRACT

OBJETIVO: Apresentar os achados em tomografia computadorizada (TC) de tórax em pacientes com papilomatose laringotraqueobrônquica. MÉTODOS: Foram estudadas, retrospectivamente, as TCs de oito pacientes, cinco masculinos e três femininos, com idades variando de 5 a 18 anos, com média de 10,5 anos. Os exames foram analisados por dois radiologistas, de forma independente, e as decisões finais foram obtidas por consenso. RESULTADOS: Os achados mais comuns nas TCs foram as lesões nodulares da traquéia e os nódulos pulmonares, muitos com escavação. CONCLUSÕES: O aspecto tomográfico mais freqüentemente observado nos casos de papilomatose laringotraqueobrônquica foi a associação de lesões polipóides de traquéia com múltiplos nódulos pulmonares, vários deles escavados.


OBJECTIVE: To present the findings of computed tomography (CT) scans of the chest in patients with laryngotracheobronchial papillomatosis. METHODS: We retrospectively analyzed CT scans of eight patients, five males and three females, ranging from 5 to 18 years of age with a mean age of 10.5 years. Images were independently reviewed by two radiologists. In discrepant cases, a consensus was reached. RESULTS: The most common CT findings were intratracheal polypoid lesions and pulmonary nodules, many of which were cavitated. CONCLUSIONS: In patients with laryngotracheobronchial papillomatosis, the most common tomographic finding was the combination of intratracheal polypoid lesions and multiple pulmonary nodules, many of which were cavitated.
