Primary intraosseous meningioma of skull is rare, and often confused with a primary bone tumor.
We report a case of a 71 years old female patient with an intraosseous calvarial meningioma of frontal bone presenting as a solitary osteolytic skull lesion.
Plain skull radiograph, CT and MR images show sharply marginated expansile bony lesion in frontal skull vault, and a small well enhanced soft tissue mass within bone. The mass is extracranially protruded to scalp, and is partially attached to the underlying dura. Outer and inner table of skull vault is slightly bulged out, suggesting intradiploic origin of the tumor.
The tumor was treated with surgical excision and cranioplasty.
Histological examination revealed fibrous meningioma.
