489: CEREBRAL VASCULOPATHY-ASSOCIATED ISCHEMIC STROKE IN THE SETTING OF BACTERIAL MENINGITIS

Abstract

Introduction: Bacterial Meningitis is known to have high morbidity and mortality rates. A less recognized complication from this disease includes acute ischemic stroke, which conveys a worse prognosis. Description: A 37-year-old previously healthy woman presented to the hospital with progressive encephalopathy associated with ataxia and dysarthria. Her immediate past travel history revealed a trip to Europe where she endured a COVID19 infection three weeks before her admission. Nevertheless, she recovered without any complications. However, she developed fatigue and headaches, prompting a diagnosis of post-COVID19 syndrome by her primary care physician. Over the course of several days, her ability to carry out her normal daily activities and perform work-related duties deteriorated as she developed severe fatigue accompanied by a painless diffuse skin rash. She presented to the ED once she started having symptoms of dysarthria, abasia, and truncal ataxia. An emergently obtained CSF sample was consistent with bacterial meningitis. Standard empiric antibiotics and steroids were administered. The patient’s condition acutely decompensated soon after antibiotics administration. A follow-up head CT showed global cerebral edema and hydrocephalus, triggering an EVD placement for ICP monitoring. An MRI brain showed multiple bilateral acute ischemic strokes in the brainstem and basal ganglia. A head CT angiography showed diffuse narrowing of the cerebral arteries. The patient ultimately completed a course of antibiotics (Neisseria PCR was positive). We used TCD-guided blood pressure augmentation to prevent the progression of cerebral ischemia. The patient was discharged on long-term steroid therapy for presumed post-infectious vasculopathy. A follow-up MRI brain did not reveal a progression of cerebral ischemia. Discussion: Bacterial Meningitis is a severe disease with significant complications. One such complication is ischemic stroke. However, the exact pathophysiology is unknown. Understanding the risks of developing cerebral ischemia and the related pathophysiology could help improve patient outcomes with better treatment modalities. The interplay between COVID19 infection and conventional infectious pathogens is an ongoing area of interest.
