Summary
Delayed hemilingual paresis after neck trauma can signal internal carotid artery dissection. Prompt diagnosis using MR imaging is crucial for identifying this rare but serious condition.
Area of Science:
- Neurology
- Radiology
- Trauma Surgery
Background:
- Blunt craniocervical trauma can lead to delayed neurological deficits.
- Internal carotid artery dissection is a significant cause of stroke, often associated with trauma.
- Lower cranial nerve palsies can occur secondary to head and neck injuries.
Observation:
- A case is presented of a patient experiencing delayed right hemilingual paresis.
- The paresis manifested after sustaining blunt craniocervical trauma.
- The patient's symptoms developed retrospectively, highlighting a delayed presentation.
Findings:
- Diagnosis was established through Magnetic Resonance (MR) imaging and MR angiography.
- Imaging findings were critical in identifying the internal carotid artery dissection.
- The study emphasizes the diagnostic utility of advanced neuroimaging in such cases.
Implications:
- This case underscores the importance of considering vascular injury in delayed neurological presentations post-trauma.
- Early recognition and diagnosis of internal carotid artery dissection are vital for timely intervention and stroke prevention.
- Understanding injury mechanisms aids in managing craniocervical trauma and associated nerve palsies.
