Headache
Patient Data
Large right anterior cranial fossa extra-axial space-occupying lesion is seen centered upon the planum sphenoidale. It elicits low to intermediate T1 signal, and intermediate to high T2/FLAIR with mild signal blooming in SWI that could represent (calcification/microhemorrhage), and shows a rather homogeneous post-contrast enhancement with the central non-enhancing area. It shows few internal and peripheral signal void structures that could represent vessels. It is seen surrounded by peri-lesional vasogenic edema.
It exerts a mass effect in the form of effacement of both frontal horns and body of the right lateral ventricle and displacement of both anterior cerebral arteries to the left side with preserved signal void and marked midline shift to the left.
Case Discussion
Anterior cranial fossa/planum sphenoidale large extra-axial space-occupying lesion, suggestive of planum sphenoidal meningioma.
