Presentation
Right-sided trigeminal neuralgia, chronic headache, and vision problems.
Patient Data
There is a right-sided petroclival meningioma with long enhancing dural tail, adjacent vasogenic oedematous changes, and midline cross associated with extension and involvement of adjacent structures as followed:
Invasion with effacement of right Meckel cave and cavernous sinus with extension to the contralateral cavernous sinus
Encasement of right ICA lacerum and cavernosal segments with marked narrowing and occlusion
Invasion of the mass to the right-sided optic canal and superior orbital fissure with optic nerve encasement associated with mass effect causing proptosis
Superior extension of the mass into the middle intracranial fossa causing pressure effect on the inferior aspect of the right temporal lobe and diencephalon structures
High signal foci in T2 and flair sequences at subcortical and periventricular white matter of both cerebral hemispheres depict microvascular ischaemic events
Case Discussion
Petroclival meningiomas had a considerable high postoperative morbidity and mortality because of tumour proximity to cranial nerves, major blood vessels, and the brainstem.
