Insights
Coronavirus disease 2019 (COVID-19) patients face risks of stroke. CT perfusion imaging effectively detected small brain infarcts in a severe COVID-19 case, aiding diagnosis and treatment.
Area of Science:
- Neurology
- Radiology
- Infectious Diseases
Background:
- Coronavirus disease 2019 (COVID-19) is linked to thromboembolic events.
- Ischemic strokes are a significant complication in COVID-19 patients.
- Early identification of cerebrovascular complications is crucial.
Observation:
- A patient with severe COVID-19 pneumonia and pulmonary embolism presented with acute neurological deficits.
- The patient exhibited sudden weakness in the right limb.
- Computed tomography (CT) perfusion imaging was utilized for diagnostic evaluation.
Findings:
- CT perfusion identified acute, small subcortical infarcts in the brain.
- The imaging findings correlated with the patient's clinical presentation of stroke.
- This highlights the utility of advanced imaging in COVID-19 neurological complications.
Implications:
- CT perfusion imaging is valuable for diagnosing acute ischemic stroke in COVID-19 patients.
- Prompt diagnosis facilitates timely management of cerebrovascular complications.
- Understanding COVID-19's neurological impact is essential for critical care.
Abstract:
Emerging evidence suggests that patients with coronavirus disease 2019 (COVID-19) are at risk of thromboembolic complications, including ischemic strokes. We present a case illustrating the value of CT perfusion to identify acute small subcortical infarcts in a patient with COVID-19 admitted to an intensive care unit for bilateral pneumonia and pulmonary embolism presenting with sudden right limb weakness.
