A chloroma or granulocytic sarcoma is an extramedullary leukemia. It can be encountered at any anatomical location, but until now only three cases have been reported in the cerebellopontine angle. We present an 8-year old patient with an extraaxial chloroma of the cerebellopontine angle to highlight this very rare and malignant pathology in the differential diagnosis of cerebellopontine angle tumors. The presented case, being the fourth chloroma in the cerebellopontine angle, occurred in the absence of relapse which is very unusual for these lesions. Chloroma should be remembered as a very rare and a malignant pathology in the differential diagnosis of pediatric cerebellopontine angle tumors. Keywords : Acute myeloblastic leukemia, Cerebellopontine angle, Chloroma, Tumor
