Extracranial primary and secondary meningiomas.

Meningioma is a well-recognized tumour of the central nervous system. However, extracranial non-dural or ectopic meningiomas are rare and in most of the reported cases, meningiomas are diagnosed only after histopathologic examination. Over the last 5 years, the authors have seen three cases. In these case reports, they discuss the salient features of these lesions, which can aid the preoperative diagnosis and management of these patients. One of the cases is a rarity, owing to the extreme extracranial position which allowed the pressure of the tumour abrade the adjacent structures. In one case, reconstruction of the skull bone using polymeric materials (Acrylic matter) was necessary. In the other two cases, titanium plates and screws were used to reconstruct the jaw.
