Possible schwannoma: neck pain and abnormal brain MRI. There is an extra-axial, lobulated, heterogeneously enhancing right suprasellar mass with extension into the right prepontine cistern that measures up to 23 mm. There is mild mass-effect upon the surrounding neurovascular structures, including the pons and optic apparatus, but no significant narrowing of the arterial flow voids. There is no evidence of intracranial hemorrhage or acute infarct. The brain parenchymal signal and pituitary gland appear unremarkable. The ventricles are normal in size and configuration. There is no midline shift or herniation. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
An extra-axial, lobulated, heterogeneously enhancing right suprasellar mass with extension into the right prepontine cistern measures up to 23 mm. Differential considerations include craniopharyngioma and meningioma, for example.
