case_images: Compared to the previous scan at initial assessment, a contrast-enhanced CT scan of the chest revealed an approximately 49 x 38 x 59 mm size heterogeneously enhancing lesion in the superior segment of the left lower lobe ( Figure 2), extending into posterior basal segment with cavitation and surrounding septal thickening, with consolidation and ground-glass opacity.
case_images: Hematoxylin and eosin-stained slide revealing tumor cells.. The circular inlet shows irregular tubules and arrow shows sarcomatoid component (20x).
