Acute Myeloid Leukemia Presenting as a Central Nervous System Mass in a Child: A Case Report.

Extramedullary leukemia is common in pediatric acute myeloid leukemia (AML) and occurs as a solid tumor (myeloid sarcoma). We report a case of a child who presented with acute onset of paraparesis and found to have intracranial and paravertebral mass; subsequently, he was diagnosed as having AML on tissue biopsy. He was started on AML treatment protocol, and later he was in remission and myeloid sarcoma got cleared from intracranial and paravertebral region. Timely diagnosis and initiation of treatment are essential to improve survival in such cases.
