Patients with IIH should get imaging to rule out secondary causes of elevated intracranial pressure, including MR imaging and Similar to an MRI – pictures are taken of the brain using magnets and radiofrequency. During the MRV though, additional pictures are taken to look… Click the term to read more of the brain. While imaging is performed to assess for secondary causes of intracranial hypertension, there are several imaging findings that can be seen with IIH. A partially empty sella turcica is a typical feature in the setting of IIH, which appears as a flattened Also known as the “master gland” it is the area of the brain that manages and makes a large portion of your hormones. Click the term to read more within an expanded sella secondary to chronically increased ICP (Fig 1).
Additionally, slit-like or small compressed ventricles can be seen, typically involving the lateral ventricles (Fig 2).
Another set of imaging findings in the setting of IIH is related to the orbits and includes posterior globe flattening, as well as dilatation of the optic nerve sheaths (Fig 3). The optic nerve sheath dilatation appears as increased Fluid that is made by specialized cells in the ventricles of the brain.
