Cardiac tamponade in the blastic crisis of chronic myelogenous leukemia.

A 36-year-old man with Philadelphia chromosome-positive chronic myelogenous leukemia (CML) developed hemorrhagic pericarditis with tamponade as a terminal manifestation of the blastic crisis. Cardiac tamponade should be kept in mind as an uncommon cause of death of CML patients. Based on a literature review, symptomatic pericarditis in patients with CML blast crisis suggests imminent death. This is in contrast to long-term survival for patients in the chronic phase.
