Meningiomas are extra-axial lesions and the most common dural tumors, which are commonly found on neuroimaging ^1,2. Most meningiomas are benign and classified as WHO grade I. A few are WHO grade II – atypical, or III - anaplastic/malignant ^1,3. The most common histological subtypes are the meningothelial meningioma, followed by fibrous and transitional subtypes ³. Clival meningiomas are uncommon and arise close to the midline of the clivus, which are related to the brainstem, vertebral arteries, basilar artery, perforating arteries, and multiple cranial nerves ^2,3,4.

This case illustrates the radiological characteristics of a clival meningioma of the transitional histological subtype, WHO I.
