An unusual presentation of lymphoma: chylotamponade.

Chylopericardium is an uncommon but potentially life-threatening clinic entity. Here we reported a case with chylopericardium causing tamponade and shock as an unusual presentation of lymphoma. The patient was managed by immediate pericardiocentesis. Further analysis of the pericardial fluid revealed immature T-cells compatible with precursor T-lymphoblastic lymphoma.
