A myeloid sarcoma (chloroma, granulocytic sarcoma,: 744 extramedullary myeloid tumor), is a solid tumor composed of immature white blood cells called myeloblasts.A chloroma is an extramedullary manifestation of acute myeloid leukemia; in other words, it is a solid collection of leukemic cells occurring outside of the bone marrow Skeletal manifestations of chloroma were reviewed in five patients.

Granulocytic Sarcoma is also known as myeloid sarcoma, chloroma, extramedullary myeloblastoma, and extramedullary myeloid tumor. Granulocytic sarcoma (chloroma): CT manifestations. Combined intra-extraspinal form of chloroma may mimic nerve sheath tumour on imaging; however, lack of profound T 2 hyperintensity with no secondary bony changes (destruction or remodelling) favours chloroma. These tumors can involve any part of the body, either concurrently or sequentially. In the fifth, an elderly patient developed a bone lesion during a blastic crisis while under treatment for chronic myelogenous leukemia.

Radiology. Three-Dimensional Volume Imaging to Increase the Accuracy of Surgical Management in a Case of Recurrent Chordoma of the Clivus. Imaging included MRI of the brain and internal au-ditory canal and CT and MRI of the cervical, thoracic, and lumbar spine. The symptomatic mass was largest resected for decompression, and granulocytic sarcoma was diagnosed. Granulocytic sarcoma (chloroma) is a rare tumor almost always associated with leukemia. After 2,500 rad (25 Gy) total brain irradiation and 10 courses of intrathecal chemotherapy, lesion be­ came low density compared with normal brain with thin enhancing rim (C and 0). Neurological symptoms may result from the local accumulation of malignant cells in or near the brain (chloroma), infection, hemorrhage, or … Isolated chloromas (granulocytic sarcomas) are rare tumors. Computed tomography and magnetic resonance imaging of the brain revealed multiple subdural masses. Median dose was 20 (6–36) Gy.

Introduction. Brain edema in brain tumors is the result of leakage of plasma into the parenchyma through dysfunctional cerebral capillaries. chloroma [klŏ-ro´mah] a malignant, green-colored tumor arising from myeloid tissue, associated with myelogenous leukemia; it can occur anywhere in the body but has an affinity for the central nervous system, bone, and soft tissues of the head and neck.
