Area of Science:

  • Oncology
  • Radiology
  • Hematology

Background:

  • Granulocytic sarcoma is a rare extramedullary tumor of immature granulocytic precursors.
  • It typically occurs during or after acute myelogenous leukemia (AML) treatment, but can be the initial sign.
  • This condition requires accurate radiologic diagnosis for timely intervention.

Observation:

  • A 13-year-old female with AML presented with unusual granulocytic sarcoma involvement.
  • Radiologic imaging focused on cranial and breast sites.
  • Magnetic resonance (MR) imaging was utilized for detailed visualization.

Findings:

  • The cranial lesion was isointense on T1- and T2-weighted MR images, with homogeneous enhancement post-gadolinium.
  • The breast mass appeared as a well-defined, lobulated lesion with heterogeneous signal and significant enhancement.

  • These findings illustrate distinct imaging characteristics of granulocytic sarcoma in different locations.

    • Implications:

    • Recognizing these specific radiologic features is crucial for diagnosing extramedullary granulocytic sarcoma.
    • Early and accurate diagnosis aids in prompt management and improved patient outcomes.
    • This case underscores the diverse manifestations of AML beyond typical bone marrow involvement.
