Background
Idiopathic intracranial hypertension is a rare neurological condition among children. Its manifestations vary from mild headaches to loss of vision. Although rare, COVID-19 infection and high dose cytosine arabinoside have been reported as risk factors for this neurological disorder. In patients with acute leukemia, idiopathic intracranial hypertension diagnosis is simple, but finding its etiology can be difficult.
Case presentation
We report a case of a 9-year-old boy with an ongoing treatment for T-acute lymphoblastic leukemia presenting with persistent headaches and diplopia. A diagnosis of idiopathic intracranial hypertension was retained based on clinical, imaging and laboratory findings. Due to its rarity, we describe its clinical and therapeutic features and highlight the challenging etiological dilemma between COVID-19 infection and high dose cytosine arabinoside administration.
Conclusion
Persistent headache in a pediatric patient with leukemia can be due to many neurological disorders other than leukemic relapse. Given the improvement of the neurological symptoms after the SARS-CoV-2 PCR negativization and the successful re-introduction of high dose cytosine Arabinoside, the diagnosis of idiopathic intracranial hypertension associated with Covid-19 infection was withheld.
