Fig. 55a: Posterior- anterior chest radiograph shows carcinomas in the left upper lobe, T1 N0 M0, stage IA, and the right lower lobe, T2 N0 M0, stage IB.

The irregular margins of the lesions speak for bronchogenic carcinomas rather than for metastatic disease. Cavitation (right lower lobe) can occur with both primary and metastatic carcinoma.

Fig. 55b: Computed tomographic scan of the chest (lung windows) shows the right lower lobe carcinoma, which is cavitated, T2 N0 M0, stage IB.
