Impending Cardiac Tamponade as the Initial Manifestation of BCR-ABL Positive Chronic Myeloid Leukemia

Area of Science:

• Hematology
• Oncology
• Cardiology

Background:

• Leukemic infiltration of the pericardium is common at autopsy.
• Clinically significant pericardial effusion leading to cardiac tamponade is a rare manifestation of leukemia.
• Patients with leukemia often have hemostatic abnormalities, increasing bleeding risks during interventions.

Observation:

• This report details a rare instance of hemorrhagic pericardial effusion in a patient with chronic myeloid leukemia (CML).
• The effusion occurred prior to the initiation of tyrosine kinase inhibitor (TKI) therapy.

Findings:

• The patient presented with cardiac tamponade due to leukemic pericardial effusion.
• Therapeutic pericardiocentesis was necessary to relieve the tamponade, posing a bleeding risk due to compromised hemostasis.
• The patient was treated with hydroxyurea and underwent pericardiocentesis.

Implications:

• This case underscores the importance of recognizing and managing rare complications like pericardial effusion in CML.
• Early intervention with procedures like pericardiocentesis and supportive treatments such as hydroxyurea may be crucial before definitive therapy.
• Further investigation into the mechanisms and optimal management of leukemic pericardial effusion is warranted.
