Patient Data

Age: 72Y/0
Gender: Female

Contrast enhanced CT scan shows an extra-axial, enhancing space occupying lesion arising from the right medial sphenoid wing and engulfed, but not encasing the right internal carotid artery, A1 segment of the anterior cerebral artery, MCA and right posterior communicating artery. There is also extension of the tumor within the right sphenoid and cavernous sinuses, and (right) orbital fossa via the superior orbital fissure. Backward displacement of the cerebral peduncle is induced by the mass as well.In addition, there is some degree of senile  brain volume loss. Expansion of the sphenoid sinus is induced by the mass (pneumosinus dilatans).

Case Discussion

She underwent a right lateral transzygomatic craniotomy to remove the tumor. Histopathology confirmed the mass to be meningioma.
