Figures

Figure 1
Figure 1. In A, an axial CT scan with a lung-window setting at the level of the lower lobes, showing small nodules in both lungs, a consolidation with cavitation in the lingula, and a nodule inside a cavity, with air interposed between the nodule and the cavity wall (the air crescent sign). In B, an axial CT scan with a mediastinal-window setting, demonstrating that the nodule is homogeneous. In C and D, axial and coronal reconstructions, respectively, of contrast-enhanced CT scans, showing intense enhancement of the intracavitary nodule.
Figura 1
Figura 1. Em A, imagem de TC axial com janela para o pulmão, ao nível dos lobos inferiores, mostrando pequenos nódulos em ambos os pulmões, uma consolidação com cavitação na língula e um nódulo dentro de uma cavidade, com ar interposto entre o nódulo e a parede da cavidade (o sinal do crescente aéreo). Em B, imagem de TC axial com janela para o mediastino demonstrando que o nódulo é homogêneo. Em C e D, reconstruções axial e coronal, respectivamente, de imagens de TC com contraste, mostrando realce intenso do nódulo intracavitário.
