Myxopapillary ependymoma (MPE), a benign histological variant of ependymoma, is found most commonly in the cauda equina region. Primary intracranial MPE is very rare, and most cases are a metastatic deposit from a spinal lesion. Primary cerebral MPEs are usually well-defined solid or cystic lesions without hemorrhage. We report the first case of primary cerebral MPE with intratumoral hemorrhage.
黏液乳头型室管膜瘤(MPE)是室管膜瘤的一种良性组织学变异型,最常见于马尾区。原发性颅内MPE非常罕见,大多数病例是脊柱病变的转移灶。原发性脑MPE通常是边界清晰的实性或囊性病变,无出血。我们报告首例伴有瘤内出血的原发性脑MPE。
