A 7-year-old boy, having had headache and vomiting for one month, was operated for a tumour in the left side of the posterior fossa. The tumour, weighing 52 g, infiltrated the dura mater, leptomeninges, and also, superficially, the left cerebellar hemisphere. The patient died five weeks after operation. Light and electron microscopical examination revealed a granulocytic sarcoma (chloroma). Pre- and postoperative blood examinations, together with postoperative and autopsy bone marrow examinations, showed no sign of acute myelogenous leukaemia. This is the second reported case of primary intracranial chloroma with no preceding sign of acute myelogenous leukemia, and the first case with cerebellar infiltration.

Granulocytic sarcoma of the parenchyma of the brain present in a patient with acute monocytic leukemia, and its unusual course during treatment, is described. Four years after diagnosis of acute monocytic leukemia, a 24-year-old man developed severe headache during its remission period. The CT scan showed large intraparencymal mass in the right frontal lobe, which was partially removed and diagnosed as granulocytic sarcoma. Following the operation, radiation in total dose of 35.5 Gy was given to the whole brain, and there was also left intraventricular administration of methotrexate (MTX) and cytosine arabinoside (ara-C). The treatment resulted in the complete disappearance of the intraparenchymal mass apart from small calcifications. Five months later, the patient redeveloped severe headache with consciousness disturbance. CT scan revealed marked swelling in the left cerebral hemisphere with irregular contrast-enhanced areas. The patient died of brain herniation in spite of conservative therapy. Photomicroscopic findings of the left cerebral hemisphere proved the presence of "disseminated leukoencephalopathy" and the absence of tumor cells. On the other hand, the right frontal lesion consisted of no tumor cells but scar tissues. This unusual feature of the CT scan in the terminal stage might be caused by combination with the effect of highly concentrated MTX in the left cerebral hemisphere because of the increased permeability of the ependym and the relatively high radiosensitivity in the non-affected left cerebral hemisphere.

Chloroma is a granulocytic sarcoma with it's characteristic greenish color. Recently there is an increased number of cases that are apparently aleukemic when the tumor mass is first presented. Recently we experienced a case of granulocytic sarcoma with characteristic green color (chloroma), which showed no evidence of leukemia in the bone marrow and peripheral blood. This patient presented headache, and was diagnosed brain tumor on computed tomography. A left parietal cranietomy was done to remove a large central dome-like mass, 8 cm, involving the dura with a slightly dusky greenish solid appearance. Compact nests of moderately mature granulocytes and immature cells comprised the tumor. Histochemical and electron microscopic studies confirmed these tumor cells as myeloid cells in varying stages of maturation. Several days after the operation, left cervical lymph nodes became palpated, and the biopsied lymph nodes revealed same neoplastic cells seen in the skull. However, bone marrow aspiration, biopsy and peripheral blood smears did not show any evidence of leukemia.

Granulocytic sarcoma is a solid tumor, composed by granulocytic precursor cells at various levels of differentiation, located at an extra-medullary site. It is associated with acute myeloid leukemia, and its presence reveals a bad prognostic factor. The treatment usually consists of radiotherapy and chemotherapy. A case of an intracranial granulocytic sarcoma occurring six months after a bone marrow transplant in a patient with acute myeloid leukemia is reported. The patient presented with headache and left hemiplegia caused by a large fronto-parietal lesion with significant mass effect. After a complete surgical resection there was a full recovery of the deficit. The patient completed radiotherapy and chemotherapy with no evidence of disease after three months of follow-up. Surgery is indicated in the presence of progressive neurological deficit. Surgical decompression may provide rapid improvement and therefore, affect quality of survival.

Granulocytic sarcoma is a tumor composed of proliferating myeloblastic cells, generally found in the orbit. A brain localization is rare. We report the case of a 11-year-old boy treated in our unit for acute myeloblastic leukemia (AML 4 Eo. FAB). After 21 months of complete remission, he developed headache and facial palsy. The CT scan visualized the presence of two frontal and occipital masses. The spinal tap revealed blastic cells in the CSF. The study of the bone morrow showed medullar relapse. A new medullar and cerebro-meningeal remission was obtained with chemotherapy and radiotherapy. CSF and the bone marrow studies can help avoid stereotaxic biopsy can be avoided in this type of tumor

A 43-year-old woman with a past medical history of breast cancer and an acute myeloid leukemia (AML) presented with headache over a 3-week period. The clinical examination was completely unremarkable. CT and MRI scans showed a contrast enhancing lesion in the left temporal lobe. Histopathologic examination revealed a malignant, hematopoietic tumor with high mitotic activity, areas of necrosis and diffuse infiltration of the brain parenchyma. Positive staining for Chloroacetateesterase and lysozyme of tumor cells identified its myeloid lineage. The diagnosis was granulocytic sarcoma (GS)/chloroma, a metastatic manifestation of AML. Granulocytic sarcoma (GS) most often occurs in patients with AML, myelodysplastic syndromes and myeloproliferative disorders, and can involve any organ. However intracerebral manifestation of GS is a rare event. In this case histopathological features and differential diagnoses of intracerebral GS are discussed.

Intracranial granulocytic sarcoma (chloroma) may occur rarely in leukemia. A 27-year-old male presented with an isolated recurrence of granulocytic sarcoma manifesting as an intraaxial mass 27 months after complete remission of acute lymphoblastic leukemia. He was admitted due to a severe headache and blurred vision. Brain magnetic resonance imaging demonstrated an enhanced mass which was initially interpreted as an extraaxial tumor in the right temporal region. Because of increased intracranial pressure and the mass effect, open biopsy with surgical resection was performed. The biopsy result indicated that intraaxial lymphoblastic leukemia infiltration had caused CNS relapse. Although granulocytic sarcoma occurs primarily in patients with acute myelogenous leukemia, the authors report a rare case of intraparenchymal granulocytic sarcoma in acute lymphoblastic leukemia.

Granulocytic sarcoma is a rare tumor composed of immature granulocytic cells. Prognosis is poor. The dura and orbits are preferentially involved. An intracranial localization is unusual. We report the case of a 31-year-old man who was admitted with a history of headache and vomiting. The neurological examination revealed hemiplegia. Computed and tomography (CT) and magnetic resonance imaging (MRI) showed a lesion which was interpreted as a meningioma. After surgical resection, pathology examination led to the diagnosis of granulocytic sarcoma. The clinical and radiological features of this case are discussed with reference to other reports in the literature.

Myeloid sarcoma is a rare extramedullary malignant tumor, which is often accompanied by the development of systemic myeloid disease at various sites. The involvement of the central nervous system is uncommon and spinal cord compression is particularly rare. In November 2012, a 27-year-old male presented with a paroxysmal headache, accompanied by nausea and vomiting, which had persisted for one year, and eyesight deterioration that had been apparent for five months. Magnetic resonance imaging (MRI) indicated a space-occupying disorder, a craniotomy to resect the brain tumor was undertaken, the pathological diagnosis of which was myeloid sarcoma. Two months after receiving 40 Gy of radiotherapy, the patient experienced numbness of the right thigh. MRI of the lumbar spinal canal revealed a mass involved both inside and outside the lumbar spinal canal. Pathological examination of the mass following resection also indicated myeloid sarcoma. Immunohistochemical analysis was positive for the ETO fusion gene in the bone marrow. Following six cycles of chemotherapy treatment, the patient achieved complete remission. At present, the patient is stable and is attending follow-up examinations regularly.

Introduction A 74-year-old man presented to hospital with a headache, thrombocytopaenia and an acute deterioration in cognition on a background of acute monocytic leukaemia in remission. Method This is a case report with computed tomography (CT), magnetic resonance (MR) and histopathology imaging. Results Preoperative CT and limited MR demonstrated a subdural lesion with marked midline shift. Craniotomy performed for evacuation of the presumed subdural haematoma revealed a solid tumour-like lesion. Histopathology identified the presence of a myeloid sarcoma (chloroma). Postoperative MRI with contrast revealed the solid nature of the mass. Conclusion The use of contrast is critical in the assessment of intracranial lesions to distinguish myeloid sarcoma from subdural haematoma in the context of leukaemia and a neurologically deteriorating patient.
