Resumo

A actinomicose pulmonar é uma situação clínica rara mas de diagnóstico importante e nem sempre fácil. Trata-se de uma infecção crónica supurativa causada por uma bactéria anaeróbia gram-positiva microfila-mentosa designada por Actinomyces.

Apresenta-se o caso clínico de um homem de 32 anos, previamente saudável, sem co-morbilidades, que de-senvolve um quadro de febre, associada a tosse produtiva e toracalgia direita.

Verificou-se a existência de alterações radiológicas sugestivas de pneumonia lobar superior direita.

Iniciou terapêutica antibiótica com amoxicilina/cla-vulanato, com melhoria clínica e analítica, contudo com persistência do achado radiológico, acabando por realizar tomografia computorizada que revelou tratar-se de condensação lobar superior direita com características discretamente expansivas.

A investigação etiológica permitiu identificar o agente responsável, o Actinomyces.

Os autores fazem uma breve revisão desta patologia.

Abstract

Pulmonary Actinomycosis is a rare clinical situation whose diagnosis is important but not always easy to make. It is a chronic infection caused by the anaerobic gram-positive filamentous bacterium Actinomyces.

We present a case report of a 32 year-old man previously healthy with no co-morbidities, with fever, productive cough and chest pain, with radiological evidence of right superior lobar pneumonia.

He began antibiotic therapy with amoxicillin/clavula-nate, with good clinical and analytic response, but the radiological finding persisted. Thoracic computerized tomography revealed discretely expansive right lobar condensation.

The epidemiological investigation identified actinomyces. The authors present this case and a brief review of this disease.
