A Case of Granulocytic Sarcoma in the Brain of a Patient with Acute Erythroleukemia

ABSTRACT

Granulocytic sarcoma is a localized tumor that's composed of immature granulocytic cells and this is more common in patient with 8;21 translocation. We present here a case in a 64-year-old man who was diagnosed with acute myelogenous leukemia (erythroleukemia) that had a complex hyperdiploid karyotype. While he underwent chemotherapy, he developed nausea, vomiting, headache and dysarthria. After several diagnostic work-ups, granulocytic sarcoma in the cerebellum and leptomeningeal metastasis of his leukemia were found on the magnetic resonance imaging and the cerebrospinal fluid cytology.
