ABSTRACT

OBJETIVO: Relatar os casos de 6 pacientes com bola fúngica (BF) na cavidade pleural por Aspergillus fumigatus. MÉTODOS: Entre 1980 e 2009, foram diagnosticados 391 pacientes com BF aspergilar no Complexo Hospitalar Santa Casa de Porto Alegre (RS). O diagnóstico de BF na cavidade pleural foi definido com exames de imagem demonstrando derrame e espessamento pleural com nível líquido; exame micológico direto demonstrando hifas septadas, consistentes com Aspergillus sp.; e cultura positiva para A. fumigatus no espécime cirúrgico da cavidade pleural. RESULTADOS: Dos 391 pacientes estudados, 6 (2 por cento) preencheram os critérios diagnósticos estabelecidos. A média de idade desses 6 pacientes foi de 48 anos (variação, 29-66 anos), e 5 (83 por cento) eram do sexo masculino. As queixas mais frequentes dos pacientes foram tosse, expectoração e hemoptise. Quatro (67 por cento) dos pacientes tinham tuberculose curada. Todos os pacientes realizaram remoção cirúrgica da colonização fúngica, e houve infusão intrapleural com anfotericina B em 4; e 2 pacientes receberam tratamento antifúngico sistêmico v.o. Cinco pacientes melhoraram clinicamente, e um foi a óbito após a cirurgia. CONCLUSÕES: Em pacientes adultos com história de doença pulmonar cavitária ou fístula pleural, deve-se realizar uma investigação criteriosa levando em consideração a infecção fúngica, principalmente BF pulmonar. Portanto, a exploração laboratorial torna-se mais eficiente em relação aos recursos disponíveis para elucidação diagnóstica.


OBJECTIVE: To report the cases of 6 patients with fungus ball caused by Aspergillus fumigatus (aspergilloma) in the pleural cavity. METHODS: Between 1980 and 2009, 391 patients were diagnosed with aspergilloma at the Santa Casa Hospital Complex in Porto Alegre, Brazil. The diagnosis of aspergilloma in the pleural cavity was made through imaging tests revealing effusion and pleural thickening with air-fluid level; direct mycological examination revealing septate hyphae, consistent with Aspergillus sp.; and positive culture for A. fumigatus in the surgical specimen from the pleural cavity. RESULTS: Of the 391 patients studied, 6 (2 percent) met the established diagnostic criteria. The mean age of those 6 patients was 48 years (range, 29-66 years), and 5 (83 percent) were male. The most common complaints were cough, expectoration, and hemoptysis. Four patients (67 percent) had a history of tuberculosis that had been clinically cured. All of the patients were submitted to surgical removal of the aspergilloma, followed by intrapleural instillation of amphotericin B, in 4; and 2 received systemic antifungal treatment p.o. There was clinical improvement in 5 patients, and 1 died after the surgery. CONCLUSIONS: In adult patients with a history of cavitary lung disease or pleural fistula, a careful investigation should be carried out and fungal infection, especially aspergilloma, should be taken into consideration. In such cases, laboratory testing represents the most efficient use of the resources available to elucidate the diagnosis.
