idiopathic intracranial hypertension mri findings

Idiopathic intracranial hypertension (IIH) can exhibit a range of characteristic findings on MRI scans. These may include, but are not limited to, optic nerve sheath dilation, the empty sella sign, abnormal cerebral venous sinus flow, brain white matter lesions, and ventricular system distortion.

Optic nerve sheath dilation is one of the most frequently observed MRI features, potentially resulting from increased intracranial pressure leading to expansion of the sheath surrounding the optic nerve. The empty sella sign indicates a collapse of the sella turcica within the pituitary fossa due to elevated intracranial pressure, which makes the pituitary gland appear smaller. Abnormal cerebral venous sinus flow is another significant MRI finding, characterized by slowed or stagnant blood flow within the venous sinuses. Brain white matter lesions could be associated with cerebral tissue ischemia and edema triggered by increased intracranial pressure. Lastly, ventricular system distortion refers to changes in the ventricle shape due to elevated intracranial pressure, such as ventricle shrinkage or deformation.

For individuals with IIH, seeking timely medical care and receiving specialized treatment is essential. The treatment approach typically encompasses medication to reduce intracranial pressure, surgical interventions, or other supportive therapies. Patients should follow a treatment plan under a physician's supervision, adhere to medical instructions, and avoid self-medicating without guidance. Additionally, maintaining a healthy lifestyle, including a balanced diet, regular exercise, and avoiding excessive fatigue, can contribute to disease management.
