Signs of meningiomas in a skull of the Mexican colonial period

The skull of a native Mexican from the colonial period is studied. The skull has a nasal trauma, dental pathology and two osteogenic lesions, one situated at the left wing of the sphenoid bone and the other in the infrainion occipital squamous bone, between the left mastoid process and the left occipital condyle. That involving the sphenoid occludes the optic nerve foramen and is evident through the orbit and at pterion. These osteogenic lesions are considered to be secondary to the soft tissue tumour mass, which, at the level of its implantation area, is usually present in meningiomas.
