Concurrent Pansinusitis and Orbital Cellulitis Complicated by Extensive Head and Neck Venous Thrombosis in an Unvaccinated Adolescent Patient with COVID-19: A Case Report.

We describe a case of a 17-year-old female patient with no significant medical history or thrombotic risk factors found to have orbital cellulitis and severe pansinusitis, complicated by multiple venous thromboses in the head and neck requiring emergent surgical intervention and pediatric intensive care admission. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Extensive head and neck venous thrombosis and intracranial abscesses are rare complications of pansinusitis and orbital cellulitis, and the thrombotic complications of COVID-19 are well documented. A delay in diagnosis and treatment can lead to potentially devastating consequences.
