Abstract:
A 63-year-old man, who had persistent fever for a month, was admitted to the hospital with sudden left arm palsy with a National Institutes of Health Stroke Scale score of 3. Consequently, brain MRI showed hyperintensity of the bilateral occipital, right parietal, and right frontal lobes on diffusion-weighted imaging. Moreover, FLAIR presented hyperintensity of the left occipital lobe. Magnetic resonance angiography detected the deficit of the blood-flow signal of the horizontal segment of the middle cerebral artery. He was diagnosed with acute ischemic stroke. In addition, chest CT showed ground-glass opacities, and test to detect SARS-CoV-2 was positive. Cerebral embolism was suspected. However, the source was unknown. His ischemic stroke was possibly associated with coagulation abnormality caused by coronavirus disease 2019.
Insights
A man with persistent fever developed acute ischemic stroke, presenting as left arm palsy. His stroke was potentially linked to blood clotting issues caused by SARS-CoV-2 infection.
Area of Science:
- Neurology
- Infectious Diseases
- Radiology
Background:
- Persistent fever can precede serious neurological events.
- Acute ischemic stroke requires prompt diagnosis and investigation of underlying causes.
- Coronavirus disease 2019 (COVID-19) has been associated with various neurological complications.
Observation:
- A 63-year-old male presented with a month of fever, followed by acute left arm palsy (NIHSS 3).
- Brain MRI revealed ischemic changes in bilateral occipital, right parietal, and right frontal lobes (DWI) and left occipital lobe (FLAIR).
- MRA showed reduced blood flow in the middle cerebral artery, confirming acute ischemic stroke. Chest CT indicated ground-glass opacities, and SARS-CoV-2 testing was positive.
Findings:
- The patient was diagnosed with acute ischemic stroke.
- Cerebral embolism was suspected, but the embolic source remained unidentified.
- The ischemic stroke was potentially associated with COVID-19-induced coagulation abnormalities.
Implications:
- This case highlights a potential link between COVID-19 and ischemic stroke, possibly due to altered coagulation.
- Further research is needed to understand the mechanisms of COVID-19-related stroke.
- Early recognition of neurological symptoms in febrile patients with positive SARS-CoV-2 tests is crucial.
