Computed tomography (CT) scanning or, preferably, magnetic resonance imaging (MRI) of the brain may be needed to rule out structural pathology. Neuroimaging study findings, including those from MRI, are usually normal in patients with CPH.

Consider obtaining an MR angiogram or arteriogram, if necessary, for atypical presentations. Electroencephalography, brain mapping, and other radiologic studies are not required for patients with typical presentations.
