Summary
Posterior fossa subdural effusion after head trauma is a treatable condition. Prompt surgical intervention, such as burr hole evacuation, leads to a good prognosis for patients experiencing acute or chronic symptoms.
Area of Science:
- Neurosurgery
- Trauma Surgery
- Neurology
Background:
- Posterior fossa subdural effusion (PFSE) is a rare complication of head trauma.
- Understanding the distinct clinical presentations and outcomes of acute versus subacute/chronic PFSE is crucial for timely diagnosis and management.
Observation:
- This study reviewed 3 new cases and 20 prior cases of PFSE following head trauma.
- Acute PFSE presented with rapid consciousness decline, nuchal rigidity, seizures, and apnea, often with occipital fractures.
- Subacute/chronic PFSE was characterized by persistent headache, cranial nerve palsies, and ataxia, frequently associated with supratentorial effusions.
Findings:
- Surgical evacuation via burr hole is the primary effective treatment for PFSE.
- Subdural-peritoneal shunting or closed drainage may be required in select cases.
- Despite the severity of symptoms, the overall prognosis for PFSE post-head trauma is favorable.
Implications:
- Early recognition of PFSE subtypes based on clinical and radiological findings is essential.
- Prompt surgical management significantly improves patient outcomes.
- Further research into the pathophysiology and optimal management strategies for PFSE is warranted.
