Can a clival lesion be benign?
Although most of the lesions show a benign behaviour, clival diseases can be potentially devastating and life-threatening [3,4]. These tumours usually present as incidental imaging findings. Patients may complain of headache or cranial neuropathies, especially diplopia due to abducens nerve palsy.
What is the clivus in the brain?
The clivus (/ˈklɪvəs/, Latin for “slope”) is a bony part of the cranium at the skull base, a shallow depression behind the dorsum sellæ that slopes obliquely backward. It forms a gradual sloping process at the anterior most portion of the basilar occipital bone at its junction with the sphenoid bone.
What bone is the clivus part of?
occipital bone
The clivus is a part of the posterior skull base where the basal occipital bone joins the sphenoid bone. The abducens nerve tracks along the clivus before it enters the cavernous sinus and ultimately the superior orbital fissure (Okudo and Anusim, 2016).
What is a Clival mass?
Clival chordomas are locally invasive tumors of the midline skull base. Clival chordomas are ideally treated with maximal safe surgical removal followed by focused radiotherapy.
What is clivus medical?
Listen to pronunciation. (KLY-vus) A bone at the base of the skull, near the spine. Tumors, such as chordomas and chondrosarcomas, may form on the clivus.
What does Clival mean?
(KLY-vus) A bone at the base of the skull, near the spine. Tumors, such as chordomas and chondrosarcomas, may form on the clivus. Enlarge.
What is a Clival meningioma?
Overview. Petroclival meningioma is a benign and slow-growing tumor that occurs deep within the center of the skull base, which is a very difficult location to reach surgically. Patients may experience headaches, double vision, hearing loss, dizziness, facial pain or numbness, facial weakness, and loss of coordination.
Where is Clival located?
skull base
The clivus is located in the midline area of the skull base. It is part of the cranium, formed by the basilar part of the occipital bone and the corpus ossis sphenoidalis.
What does clival mean?
What kind of tumor is on the Clivus?
Clival Tumors The clivus is the surface of a portion of the occipital and sphenoid bones in the base of the skull. It is surrounded by the neurovascular structures of the brainstem, as well as both internal carotid arteries. Tumors of the clivus can be benign or cancerous; they can be classified as chordomas or chondrosarcoma.
Where are clival tumors located in the skull?
Clival tumors are growths on the clivus, a portion of bone at the base of the skull. When clival tumors grow, they may invade and damage important nearby structures: cranial nerves, the internal carotid arteries and the brainstem, for example.
Can a tumor on the clival bone be benign?
Clival Tumors. The clivus is the surface of a portion of the occipital and sphenoid bones in the base of the skull. It is surrounded by the neurovascular structures of the brainstem, as well as both internal carotid arteries. Tumors of the clivus can be benign or cancerous; they can be classified as chordomas or chondrosarcoma.
How are the masses of the Clivus divided?
The differential of a mass involving or arising from the clivus is a relatively narrow one and can be divided into whether the lesion arises from the skull base itself, the intracranial compartment above or the base of skull below.
