Here, we report a case of primary intraosseous meningioma which presented as a Bifrontal skull mass in a 30-year-old woman who presented with a progressive forehead enlargement and headache of 3 years duration. Brain CT shows hyperostosis of the frontal bone and microscopy shows intertrabecular syncytial proliferation of oval to spindle cells at the area forming whorl. Even though it is rare, PIM is the most common subtype of extradural meningioma.Keywords: bifrontal, PIM, calvarium, meningioma
