On HRCT scans, lung cysts are characterized by rounded areas of low attenuation in the lung parenchyma and a well-defined interface with the normal adjacent lung. The most common cystic lung diseases are lymphangioleiomyomatosis, Langerhans cell histiocytosis, and lymphocytic interstitial pneumonia. In a retrospective analysis of the HRCT findings in 50 patients diagnosed with chronic paracoccidioidomycosis, we found lung cysts in 5 cases (10%), indicating that patients with paracoccidioidomycosis can present with lung cysts on HRCT scans. Therefore, paracoccidioidomycosis should be included in the differential diagnosis of cystic lung diseases.

Os cistos pulmonares na TCAR são caracterizados por áreas arredondadas de baixo coeficiente de atenuação no parênquima pulmonar com uma interface bem definida com o pulmão adjacente normal. As doenças pulmonares císticas mais comuns são linfangioleiomiomatose, histiocitose de células de Langerhans e pneumonia intersticial linfocítica. Em uma análise retrospectiva de achados de TCAR em 50 pacientes com diagnóstico de paracoccidioidomicose crônica residual, observou-se a presença de cistos pulmonares em 5 casos (10%), mostrando que pacientes com paracoccidioidomicose podem apresentar cistos pulmonares na TCAR. Portanto, essa infecção deve entrar no diagnóstico diferencial das doenças císticas pulmonares.
