Intracranial myeloid sarcoma: conventional and advanced MRI findings.
Chloroma (myeloid or granulocytic sarcoma) is a rare type of tumour comprising immature granulocytic cells. It generally accompanies acute myeloid leukaemia and, rarely, other myeloproliferative disorders. When presenting as dural-based mass lesions, radiological differential diagnosis includes meningioma, metastasis and lymphoma. There is a limited number of descriptions of chloromas mimicking dural-based masses in the literature. We present preliminary diffusion-weighted MR, perfusion-weighted MR and MR spectroscopy findings of an intracranial myeloid sarcoma.
