Intradiploic meningioma is a rare subtype of primary intraosseous meningiomas. The convexity and the skull base are the two primary locations for intraosseous meningiomas. They usually present as a painless expansile mass without any neurological findings. Intradipoic meningiomas are seldom correctly diagnosed preoperatively and are usually mistaken for primary bone tumours. CT scan head with bone windows and contrast-enhanced MRI brain should be done for diagnosis and evaluation. Intraosseous meningioma should be considered in the differential diagnosis of patients presenting with osteoblastic or osteolytic skull lesions as the treatment of choice is resection, which is potentially curative.
