Bilateral Longus Colli Abscesses as a Complication of Advanced Bacterial Rhinosinusitis.

Known complications of acute bacterial rhinosinusitis include retropharyngeal abscess, cavernous sinus thrombosis, intracranial abscess, and associated sequelae. We describe the case of a patient with longus colli abscess formation resulting from acute pansinusitis, complicated by bilateral cavernous sinus thrombosis in the setting of concurrent viral pneumonitis, severe sepsis, and a large area cerebral infarction. The bilateral longus colli abscesses were drained via stereotactic image-guided endonasal sinus surgery, yielding Staphylococcus hominis in culture. The described disease progressed rapidly over a 2-week course amid the COVID-19 pandemic.
