Presentation
The male started symptoms six months ago, presenting facial paralysis, headaches, and vomiting.
Patient Data
At the level of the prepontinal cistern on the right side, dependent on the tent of the cerebellum, an extra-axial image of defined, homogeneous, oval morphology is displayed, with isointense behavior in T1 and T2 and hyperintense behavior in FLAIR. This lesion presents avid enhancement after the application of paramagnetic contrast; the sign of the dural tail is identified; it measures approximately 20 mm; and conditions a mass effect, producing a discrete displacement of the protuberance.
Case Discussion
The typical meningioma is a homogeneous, hemispheric, markedly enhancing extra-axial mass located over the cerebral convexity, in the parasagittal region, or arising from the sphenoid wing.
Meningiomas are typically benign, common extra-axial tumors of the central nervous system. Routine clinical assessment by radiologists presents some limitations regarding long-term patient outcome prediction and risk stratification. Given the exponential growth of interest in radiomics and artificial intelligence in medical imaging, numerous studies have evaluated the potential of these tools in the setting of meningioma imaging.
