Chronic subdural hematoma presenting as transient neurologic deficits
Insights
Transient neurological episodes in four patients were linked to chronic subdural hematomas (CSDH). Surgical evacuation of CSDH significantly reduced these neurological events, suggesting CSDH can mimic transient ischemic attacks (TIAs).
Area of Science:
- Neurology
- Neurosurgery
- Radiology
Background:
- Transient neurological dysfunction can be challenging to diagnose.
- Chronic subdural hematomas (CSDH) are often associated with head trauma but can present insidiously.
- Transient ischemic attacks (TIAs) are typically attributed to cerebrovascular events.
Observation:
- Four patients presented with symptoms mimicking TIAs.
- These patients were diagnosed with underlying chronic subdural hematomas (CSDH).
- A reduction in neurological episodes was observed post-hematoma evacuation.
Findings:
- CSDH can manifest as transient neurological dysfunction.
- Surgical evacuation of CSDH led to a significant decrease in neurological episodes.
- The neurological effects of CSDH may be additive to other vascular insults.
Implications:
- CSDH should be considered in the differential diagnosis of presumed TIAs.
- Computerized axial tomography (CAT) scans are valuable for diagnosing CSDH in patients with neurological symptoms.
- Early diagnosis and treatment of CSDH can improve patient outcomes and reduce neurological deficits.
Abstract:
Four patients with symptoms of transient neurological dysfunction were subsequently found to have chronic subdural hematomas (CSDH). The frequency of these episodes diminished significantly after evacuation of the hematoma. The effects of vascular compromise due to the CSDH and to cardiovascular events, more commonly implicated in transient ischemic attacks (TIAs) may be additive. The inclusion of a computerized axial tomographic (CAT) scan in the evaluation of some patients with presumed TIAs is recommended.
