Man coughs up blood clot in perfect shape of bronchial tree
SAN FRANCISCO – Doctors at UC San Francisco Medical Center see a lot of things, but even they were stunned by this.
They were treating a 36-year-old man with end-stage heart failure when he began coughing so violently, that he coughed up a 6-inch-wide blood clot from his lungs in the near-perfect shape of his right bronchial tree.
