Lung adenocarcinoma presenting as consolidation

Case contributed by Stefan Tigges
Diagnosis almost certain

Presentation

Cough for 6 months.

Patient Data

Age: 50 years
Gender: Male

Portable chest x-ray and CT scanogram images show left lower lobe mass-like consolidation.

CT scan confirms left lower lobe consolidation. Air bronchograms are present. The right lung is clear, there is no pleural or pericardial effusion, the central airways are patent. No lymphadenopathy.

Case Discussion

This "pneumonia" failed to clear: a subsequent biopsy showed adenocarcinoma. Lymphoma and adenocarcinoma both may have air bronchograms and are two neoplasms that should be considered if pulmonary consolidation persists despite treatment.
