Primary calvarial ectopic meningiomas.
Meningiomas should be considered as a possible diagnosis when dealing with tumors of the head and neck, even though these lesions may be located outside the cranial cavity. We report three patients who harbored primary ectopic epidural meningioma arising in the right occipital, parietal and left frontal region protruding extracranially through destructed calvarium and also developing intracranially without dural involvement. The diagnostic value of CT scan is emphasized and the relevant literature on ectopic meningioma is reviewed.
