# Idiopathic intracranial hypertension associated with SARS-CoV-2 infection in an adult male patient: a case report and review of the literature

## TL;DR

A man with SARS-CoV-2 infection developed idiopathic intracranial hypertension, showing headache and vision issues, and improved with treatment.

## Contribution

This case report highlights a rare association between SARS-CoV-2 infection and idiopathic intracranial hypertension in an adult.

## Key findings

- A 45-year-old man with SARS-CoV-2 infection presented with idiopathic intracranial hypertension and visual symptoms.
- Medical therapy successfully improved symptoms despite normal CSF analysis and MRI findings.
- The case suggests SARS-CoV-2 may contribute to intracranial hypertension even without typical risk factors.

## Abstract

Headache is a frequent symptom in coronavirus disease 2019 (COVID-19) patients, and idiopathic intracranial hypertension (pseudotumor cerebri) has been reported among patients who underwent lumbar puncture for persistent headaches.

A 45-year-old black man presented with dyspnea, cough, fever and headache for 05 days followed by blurring of vision associated with worsening of the headache. Physical examination was significant for tachypnea and oxygen desaturation and there were no abnormal neurologic findings. He tested positive for SARS-CoV-2 with nasopharyngeal swab PCR. His CSF opening pressure appeared high with normal CSF analysis and brain magnetic resonance imaging (MRI) revealed prominent subarachnoid space around the optic nerves and bilateral papilledema. He had significant improvement with medical therapy alone.

Idiopathic intracranial hypertension (IIH) may occur in association with SARS-CoV-2 infection and should be considered when making a differential diagnosis for headache and blurring of vision. COVID-19 may play a role in the development of intracranial hypertension, even in the absence of known risk factors. Early diagnosis and treatment of IIH has paramount importance to prevent vision loss and other morbidities.
