What to clinically suspect in persistent pulmonary consolidation and bronchorrhea

What to clinically suspect in persistent pulmonary consolidation and bronchorrhea?

Invasive mucinous lung adenocarcinoma, formerly known as mucinous bronchioloalveolar cell lung carcinoma. Note that comparison with prior imaging studies is of utmost importance to establish that an underlying etiology of pulmonary consolidation is chronic, as this prolonged time course would in general not be expected with other etiologies such as pneumonia or aspiration that typically have a more acute time course of evolution.
