Extramedullary leukemia in pediatric acute myeloid leukemia can manifest as a myeloid sarcoma (MS), also known as granulocytic sarcoma or chloroma, in a variety of sites, or as leukemic blasts in the cerebrospinal fluid. Isolated MS of the central nervous system is rare. We report a case of acute myeloid leukemia with central nervous system-MS presenting as a posterior fossa mass mimicking a primary intracranial tumor.
儿童急性髓系白血病中的髓外白血病可表现为各种部位的髓样肉瘤（MS），也称为粒细胞肉瘤或绿色瘤，或脑脊液中的白血病细胞。孤立性中枢神经系统 MS 较为罕见。我们报告了一例急性髓系白血病伴中枢神经系统 MS，表现为后颅窝肿块，类似于原发性颅内肿瘤。
