3. • Fig C 9-1 Septic pulmonary emboli. Multiple cavitating
nodules (Nocardia) in a young immunocompromised
man. Note the feeding vessel sign (vessel leading
directly to the nodule) in several nodules (arrows).30

4. • Fig C 9-2 Blastomycosis. Multiple
intermediate-sized nodules in a patient with
persistent and worsening symptoms of cough,
chest pain, and fevers.23

5. • Fig C 9-3 Hematogenous metastases. Several
cavitating nodules (arrows) in both lower
lobes with irregular thickening of the walls in a
patient with metastatic squamous cell cancer
of the lungs.22

6. • Fig C 9-4 Kaposi's sarcoma. Innumerable,
bilateral, poorly defined peribronchovascular
micronodules, some of which exhibit
coalescence.6

7. • Fig C 9-5 Bronchioloalveolar carcinoma. (A)
Ground-glass lesions bilaterally. The mass in the
left lower lobe also contains solid elements,
consistent with the diagnosis of bronchoialveolar
carcinoma with adenocarcinoma features.

Multiple thin-walled cystic lesions in the right
lower lobe.122

8. • Fig C 9-6 Pulmonary papillomatosis. Multiple
cavitating lung nodules, some of which
contain air-fluid levels.25

9. • Fig C 9-7 Lymphoma. Multiple pulmonary
nodules on a study obtained 10 months after
cardiac transplantation.123

10. • Fig C 9-8 Wegener's granulomatosis. Multiple
irregular nodules in a peribronchovascular
distribution.109

11. • Fig C 9-9 Rheumatoid necrobiotic nodules. Two large,
pleural-based nodules (large arrows) are seen at the level of
the left upper lobe. The nodules are associated with
marked posterior left-sided pleural thickening (small
arrows).147

12. • Fig C 9-10 Sarcoidosis. Two images show
parenchymal nodules of high attenuation
involving both lungs.148

13. • Fig C 9-11 Progressive massive fibrosis.
Conglomerate masses and adjacent small nodules
in coal workers' pneumoconiosis. The arrowhead
points to a thoracostomy tube that was placed in
the left hemithorax for a pneumothorax.149

14. • Fig C 9-12 Talc-induced lung disease. Bilateral
irregular nodular areas of high attenuation in
the upper lobes.10
