In the week of his hospitalization, the coughing of the man progressed to the formation of blood and mucus. During a rather extreme hack, he coughed "an intact imprint of the right bronchial tree," the article says.
"The right bronchial tree consists of three segments in the upper lobe, two segments in the middle lobe, and five segmental branches in the lower lobe," wrote the authors of the journal, "the patient's trachea was then intubated, and the flexible bronchoscopy showed a small amount Blood in the basilar branches of the right lower lobe. "
The man was extubated two days after the incident, he suffered no further cases of hemoptysis.
