Case report: granulocytic sarcoma (chloroma) presenting as a cerebellopontine angle mass.

Granulocytic sarcomas (chloromas) are rare, solid extramedullary tumours composed of granulocyte precursors occurring in association with granulocytic leukaemia. A cerebellopontine angle granulocytic sarcoma in a 4-year-old child presenting with unilateral facial palsy is reported. The computed tomographic (CT) findings are described, with a review of the literature, and the significance of early diagnosis is discussed.
