Summary
Acute aortic dissection can present unusually, even with leg numbness. This case highlights the importance of considering aortic dissection in neurological diagnoses to ensure timely treatment.
Area of Science:
- Cardiology
- Neurology
- Vascular Surgery
Background:
- Acute aortic dissection (AAD) presents variably, complicating diagnosis.
- Neurologic syndromes are uncommon but critical manifestations of AAD.
- Prompt diagnosis of AAD is vital for patient outcomes.
Observation:
- This report details the first case of thoracic aortic dissection presenting with unilateral lower extremity numbness.
- The patient's chief complaint was isolated sensory deficit in the leg.
- Peripheral ischemic neuropathy secondary to vascular occlusion is a rare complication.
Findings:
- AAD can manifest as peripheral ischemic neuropathy.
- Vascular occlusion in dissection leads to nerve ischemia.
- Understanding the pathophysiology is key to recognizing this presentation.
Implications:
- Clinicians must include aortic dissection in the differential diagnosis for unexplained neurologic deficits.
- Early recognition of AAD presenting with neuropathy can prevent severe complications.
- This case expands the known spectrum of AAD presentations.
