The #clivus is a bony part of the cranium found at the skull base and is a shallow recession at the back of the dorsum sellae that inclines obliquely backwards. It creates a gradual sloping process at its junction with the #sphenoid bone at the forward most part of the basilar occipital bone. https://www.earthslab.com/anatomy/clivus/
Two types of tumors grow in the clivus: chordomas and chondrosarcomas. The most common surgical treatments for tumors of the clivus are craniotomy and transsphenoidal surgery.
Chordomas are rare, benign tumors that arise from cells that were once part of an embryonic structure called a notochord. Normally, notochord remnants form part of the intervertebral discs. A #chordoma occurs when additional notochord cells are enclosed by the developing bones.
Chordomas in the skull have a slow-growing nature and are typically benign. Despite their mild behavior, however, they can still cause significant damage by invading nearby structures. Chordomas tend to recur after treatment.
The second type of clival tumor, #chondrosarcoma, is even rarer. Chondrosarcomas are slow-growing tumors that arise in cartilage. (During development, the cartilage in the skull eventually hardens and is replaced by bone.) Although chondrosarcomas are malignant, they rarely spread to other areas. Like chordomas, chondrosarcomas tend both to invade nearby structures and to recur after treatment. https://www.neurosurgery.columbia.edu/patient-care/conditions/clival-tumors

Common brain lesions on FLAIR MRI
Fluid-attenuated inversion recovery (FLAIR) is an MRI sequence with an inversion recovery set to null fluids. For example, it can be used in brain imaging to suppress cerebrospinal fluid (CSF) effects on the image, so as to bring out the periventricular hyperintense lesions.
The FLAIR sequence analysis has been especially useful in the evaluation and study of CNS disorders, involving:
β Lacunar infarction
β Multiple sclerosis (MS) plaques
β Subarachnoid haemorrhage
β Head trauma
β Meningitis and other leptomeningeal diseases
