Spaces within the pericardium formed by reflections of the pericardium
Can become fluid filled = basically a cyst in the pericardium
Different names and sources based on where the fluid came from - nobody cares and too much to really memorize
Eustachian Valve
Fetal remnant tissue at IVC-RA junction that can be mistake for a thrombus or atrial mass
