Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can cause rare neurological complications, including subdural effusion. This case highlights a unique instance of rapid subdural effusion absorption following SARS-CoV-2 infection.
Area of Science:
- Neurology
- Infectious Diseases
- Neuroscience
Background:
- The neurological impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is not fully understood.
- Manifestations range from mild symptoms to severe neurological complications.
- Intracranial complications of SARS-CoV-2 infection are rare.
Observation:
- A 56-year-old male with SARS-CoV-2 infection developed cerebral infarction with hemorrhagic transformation.
- He subsequently developed an idiopathic subdural effusion.
- The subdural effusion resolved spontaneously within 6 days.
Findings:
- Subdural effusion is a rare intracranial complication associated with SARS-CoV-2.
- Rapid spontaneous absorption of subdural effusion can occur.
- No recurrence was noted during a 3-month follow-up.
Implications:
- This case expands the spectrum of known neurological complications of SARS-CoV-2.
- It suggests that subdural effusions, though rare, should be considered in patients with SARS-CoV-2.
- Further research is needed to understand the mechanisms and management of such complications.
