Confirmation of Elevated Intracranial Pressure in Arrested Hydrocephalus by Optic Nerve Ultrasonography Arrest Hidrosefalide Artmış İntrakraniyel Basıncın Optik Sinir Ultrasonografisi ile Doğrulanması

Introduction: Arrested hydrocephalus is a state of chronic hydrocephalus with mild dilatation of the ventricles in which the cerebrospinal fluid pressure has returned to normal, and there is no pressure gradient between the cerebral ventricles and brain parenchyma. Case Report: In this case report, we present a 37-year-old female patient who was admitted to emergency department with complaints of headache, photophobia, and recurrent vomiting. She had been diagnosed with arrested hydrocephalus 5 years ago and was being followed radiologically since. Ocular ultrasonography was successfully utilized to assess and diagnose acute exacerbation of hydrocephalus. Conclusion: Patients who are presumably assumed to have arrested hydrocephalus may experience an episode of hydrocephalus in any period of life. Ultrasonography can serve as a reliable tool in monitoring hydrocephalus; more specifically, sonographic visualization of the optic nerve sheath diameter may help to confirm increased intracranial pressure in such cases.
