Skull Base Diseases 

Lesions and tumors in the skull base can be located in several areas:

  • Intracranial:
    Arising from the meninges, cranial nerves, blood vessels, pituitary gland or brain tissue.
  • Extracranial:
    Involving the paranasal sinuses, nasal cavity, nasopharynx, parapharyngeal space, infratemporal fossa, and temporal bone.
  • Orbital:
    Located in the eye socket, arising from its contents, or at the cranio-cervical spine junction where it can involve the foramen magnum and C1 and C2 vertebrae.

Types of lesions located in the skull base may include:

  • Benign or malignant tumors
  • Vascular processes (aneurysm, arterial venous malformation, cavernous malformation)
  • Congenital disorders (chiari malformation, basilar invagination)
  • Pain syndromes (trigeminal neuralgia)
  • Rheumatological disorders (rheumatoid arthritis C1-C2 subluxation)
