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 an end-stage heart failure when he started 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.
The bright mass that looks like coral is a blood clot.
The doctors were shocked, calling what happened extremely rare.
Despite doctors' best efforts, the man passed away a few days later.
The information was provided by the New England Journal of Medicine.
