Participants and data sources
A retrospective review of paediatric patients (<18 years)
presenting with sinusitis and one of the following intracranial
complications confirmed on cross-sectional imaging including EDA, SDE
and IPA was performed. Medical records were reviewed to obtain the
demographic and clinical characteristics. Images and their reports were
reviewed to confirm the diagnosis and document sinus involvement, the
depth of an intracranial abscess and the type of collection.
