Fibrinous pericarditis is seen in?
Fibrinous inflammation occurs as a consequence of more severe injuries, resulting in greater vascular permeability that allows large molecules (such as fibrinogen) to pass the endothelial barrier. Histologically, the accumulated extravascular fibrin appears as an eosinophilic meshwork of threads or sometimes as an amorphous coagulum. Robbins Basic pathology,9th edition,pg no.43
