图示心包炎时不但有纤维素形成，而且还有出血。因此，被称作“出血性心包炎”。但是它仅为纤维素性心包炎合并出血。在心包腔里没有炎症仅有出血，称作心包积血。
The pericarditis here not only has fibrin, but also hemorrhage. Thus, this is called a "hemorrhagic pericarditis". It is really just fibrinous pericarditis with hemorrhage. Without inflammation, blood in the pericardial sac would be called "hemopericardium".
