Association Between Novel Coronavirus Disease 2019 (COVID-19) and Idiopathic Intracranial Hypertension

Introduction: Idiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri, is a rare neurological manifestation of coronavirus disease 2019 (COVID-19) infection. Case Presentation: In this case study, we present a 10-year-old girl with headache, diplopia, bilateral sixth nerve palsy, and papilledema following a history of seven days of fever about two weeks ago. In lumbar puncture, the opening pressure was 56 cmH2O. Cerebrospinal fluid analysis was normal. Brain magnetic resonance imaging (MRI) was suggestive of IIH. Nasopharyngeal reverse transcription-polymerase chain reaction (RT-PCR) was positive for COVID-19. Oral acetazolamide was prescribed, and the patient improved completely after three weeks of continuous medical treatment. Conclusions: Since IIH is a rare neurological complication of COVID-19, we have to suspect COVID-19 infection in any patient with IIH.
