Cardiac granulocytic sarcoma (chloroma): in vivo diagnosis with transesophageal echocardiography

Area of Science:

• Hematology
• Cardiology
• Oncology

Background:

• Granulocytic sarcoma (chloroma) is an extramedullary manifestation of acute myeloid leukemia.
• Cardiac involvement by granulocytic sarcoma is exceptionally rare, often discovered post-mortem.

Observation:

• This case highlights the diagnostic utility of transesophageal echocardiography (TEE) for in vivo detection of cardiac granulocytic sarcoma.
• Specific imaging features indicative of cardiac granulocytic sarcoma via TEE are detailed.

Findings:

• TEE provides detailed visualization of cardiac masses and their characteristics.
• The study describes the key echocardiographic findings associated with granulocytic sarcoma in the heart.

Implications:

• Early in vivo diagnosis of cardiac granulocytic sarcoma using TEE can potentially alter patient management.
• This case underscores the importance of considering rare presentations of leukemia, even in cardiac structures.
