Meningioma is a common benign intracranial neoplasm. The incidence of an extracranial extension to other sites is rare. Due to the neglected intracranial component, the chances of an under diagnosis or a misdiagnosis of the extracranial component is there, which may adversely affect the management and therefore, the prognosis. Here, we are reporting a case of a 39 years old male patient with a preoperative probable diagnosis of a malignant bone tumour which involved the skull bone, which was made, based on the imaging studies , which was histopathologically found to be an invasive meningioma with an extensive extracranial skull vault involvement and was confirmed by immunohistochemistry. We have proposed a term, “carpet meningioma” for this extracranial invasive meningioma, because it had covered the skull vault like a carpet. The follow up studies after 1 year have revealed no evidence of a recurrence.
