Abstract

Papillary meningioma is rare meningeal tumors and is associated with aggressive clinical behavior as compared with other meningiomas. We report a case of papillary meningioma in a 50-year-old woman presented with complaints of headache, nausea and vomiting. MRI revealed a very macrolobulated heterogeneously enhancing solid mass at the right frontal convexity with focal prominent inward infiltrating portion and surrounding moderate brain edema. The localization of the lesion as intra-axial or extra-axial in origin was difficult. Demonstrated diffusion restriction and high relative cerebral blood volume value were similar to conventional meningioma, but hypervascular inward infiltrating portion could be seen in papillary meningioma. The histopathology examination of the resected tissues revealed papillary meningioma with an increased cellularity and high nuclear/cytoplasm ratio. She underwent radical excision of the tumor, followed radiotherapy and tumor recurrence occurred at 12 months later.
