Their management involves surgery, radiosurgery, radiotherapy and, more recently, targeted therapies. The strategy is adapted not only to the characteristics of the cerebral localizations, but also to the overall status of the primary disease (degree of extension, impact on the patient's clinical condition, lines of chemotherapy available).

Early diagnosis and multidisciplinary management is the key to effective treatment of these tumors.

Because of their location, injuries to the base of the skull can cause a wide range of symptoms, including visual, hearing, smell, balance and swallowing disorders, headaches, facial asymmetry, sensitivity disorders and/or facial pain, nasal obstruction, vertigo...

Cerebral CT andMRI scans are the main tests used to identify the lesion. CT scans enable precise assessment of bone structures, but lack spatial resolution for soft tissues. MRI enables precise assessment of the soft tissues, the lesion and its relationship with surrounding structures. Other tests may be ordered depending on the type and location of the suspected lesion:

- cerebral angioscan, MRI angiography and/or arteriography to assess the vascularity of the lesion, its relationship with the major vessels supplying the brain, such as the internal carotid and vertebral arteries, and the anatomy of the cerebral drainage veins, in order to preserve them as much as possible,

- an ophthalmological check-up

-an ENT check-up to assess hearing, balance and swallowing skills

-an endocrinological check-up to assess any possible repercussions of the lesion on the functioning of the pituitary gland, a small gland connected to the brain and located at the center of the skull base
