Radiographic features of granulocytic sarcoma (chloroma)

The computed tomographic (CT) findings in two patients in whom intracranial granulocytic sarcomas preceded the onset of systemic myelogenous leukemia are presented. On CT, granulocytic sarcomas may be indistinguishable from meningiomas and difficult to differentiate from primary central nervous system malignant lymphoma and eosinophilic granuloma.
