BACKGROUND: Optic disk drusen (ODD) in pediatric patients typically presents with pseudopapilledema. Diagnosing concomitant papilledema due to idiopathic intracranial hypertension (IIH) in these patients can be challenging. The purpose of this study was to evaluate the incidence and clinical features of papilledema due to IIH among pediatric patients with a new diagnosis of ODD and to discuss the clinical and paraclinical findings that helped diagnose this group. METHODS: The medical records of children <15 years of age with ODD confirmed by B-scan ultrasound at their first visit over a 4-year period (2019-2022) were reviewed retrospectively. Patients with concurrent IIH were identified, and the demographic and clinical characteristics were reviewed. RESULTS: A total of 83 children with confirmed ODD at the initial presentation were included, of whom 4 (4.8%) were diagnosed with concomitant IIH. Patients ranged in age from 7 to 15 years; 3 of the 4 were female, and 3 had IIH-related symptoms at presentation (1 was asymptomatic). None of the 4 patients had papilledema greater than Frisen grade 2. CONCLUSIONS: We recommend that clinicians review pertinent IIH symptoms and risk factors in children with ODD and follow the standard workup for IIH in suspicious cases. In asymptomatic patients with a new diagnosis of ODD, we recommend obtaining a follow-up optic nerve evaluation and optical coherence tomography scan to detect any significant interval change that might serve as a possible indicator of concomitant papilledema.
