Cerebral Venous Sinus Thrombosis Following Pneumococcal Meningitis: A Rare but Serious Complication.

Cerebral venous sinus thrombosis (CVST) is a rare but important complication of bacterial meningitis and is most commonly associated with Streptococcus pneumoniae. We report the case of a 60-year-old man who developed extensive CVST following the completion of a 14-day course of intravenous ceftriaxone for pneumococcal meningitis. Despite biochemical resolution of infection and absence of focal neurological deficits, persistent headache and meningism prompted further neuroimaging, which confirmed the diagnosis. He was treated with anticoagulation, resulting in subsequent radiological resolution of thrombosis, although headaches persisted following recanalisation.
