Massive pulmonary emboli can cause an abrupt onset of symptoms simultaneous with large pulmonary artery occlusions. In contrast, the temporal relationship between pulmonary vascular occlusion by smaller emboli and the development of symptoms of pulmonary infarction is unknown. We describe the time interval between embolization and the onset of clinical symptoms and signs compatible with pulmonary infarction. ⋯ The clinically silent time interval between embolization of a pulmonary artery and the onset of symptoms and signs compatible with lung infarction is 24 hours or greater.

A Woman in Her 60s With Lung Adenocarcinoma Presents With Copious Watery Sputum and Respiratory Failure.
A woman in her 60s presented with 1 month of progressive dyspnea, watery rhinorrhea, and paroxysmal cough productive of clear, watery sputum. She was diagnosed with epidermal growth factor receptor (EGFR) mutation-positive lung adenocarcinoma at another institution 1 week prior to presentation and 3 weeks after the onset of symptoms. ⋯ She denied fevers and had completed a course of antibiotics for presumed pneumonia, without clinical improvement.
