Granulocytic sarcoma (chloroma) of bone: The CT appearance

Abstract

Granulocytic sarcoma (chloroma) is an unusual tumour usually seen in cases of myelogenous leukemia. The tumour is most commonly located in the skull, orbits and sinuses. Extracranial tumours occur mainly in the soft tissues of the body and bone involvement is uncommonly seen and is almost invariably lytic in nature:. We describe the first case of CT demonstration of bone involvement by such a tumour. A mixed sclerotic and lytic pattern was seen.
