Primary isolated chylopericardium is a rare disorder in which chylous fluid
accumulates in the pericardial space. Ln this case report of a 61-year-old
man with chylopericardium, pedal Tc-99m-sulfur colloid (SC) lymphoscintigr
aphy was performed after emergent pericardiocentesis, and when there was a
recurrent massive pericardial effusion. The results showed that Tc-99m-SC l
ymphoscintigraphy can cleat-iv reveal the lymphodynamics in patients with p
rimary isolated chylopericardium. This noninvasive investigation is valuabl
e and can be easily performed either before of after pericardiocentesis.
