Abstract：Objective: To elucidate imaging diagnosis of multiple gliomas and correlate to pathology. Materials and Methods: Retrospectively analyze the CT and MRI imaging of 8 patients with multiple gliomas confirmed by surgery and pathology. Result: Sixteen gliomas were confirmed by pathology with 2 tumors in each patient. 5 patients were multicentric and 3 patients were mutifocal. 3/5 patients with multicentric had different histotypes. 2 patients were mixed glioma or oligodendroglioma(grade Ⅱ) accompanied with astrocytoma(grade Ⅱ). One patient was DNET with oliogodendrocytoma component accompanied with a pure DNET. 2/5 patients with multicentric had same histotype of anaplastic astrocytomas(grade Ⅲ). All 3 patients with multifocal glioma had same histotype. 1 was anaplastic astrocytomas(grade Ⅲ). 2 were glioblastoma multiform(grade Ⅳ). Conclusion: The histotype of multicentric gliomas may be same or different. When it is different, we can make the correct diagnosis by the imaging appearance of each glioma. When it is same, the differential diagnosis should include metastases and lymphoma.
