Aortic dissection can mimic subarachnoid hemorrhage, presenting with severe headache and neck stiffness. This case highlights the importance of considering aortic dissection in patients with neurological symptoms and normal initial brain imaging.

Area of Science:

  • Cardiology
  • Neurology
  • Radiology

Background:

  • Proximal aortic dissection is a life-threatening condition often associated with chest pain and neurological deficits.
  • Subarachnoid hemorrhage typically presents with sudden severe headache, neck stiffness, and altered consciousness.

Observation:

  • A comatose patient presented with symptoms mimicking subarachnoid hemorrhage, including severe headache, neck stiffness, and opisthotonos.
  • Initial cardiovascular examination, chest radiograph, and cerebral computed tomography were unremarkable.
  • Thoracic computed tomography performed eight hours later confirmed proximal aortic dissection.

Findings:

  • Aortic dissection can manifest with neurological signs and symptoms that overlap with subarachnoid hemorrhage.
  • The absence of classical aortic syndrome symptoms does not exclude aortic dissection.

Implications:

  • This case underscores the need for a broad differential diagnosis in patients presenting with acute neurological changes.
  • Clinicians should maintain a high index of suspicion for aortic dissection, even with normal initial neurological and cardiovascular assessments.
  • Prompt and comprehensive imaging is crucial for accurate diagnosis and timely management of potentially fatal conditions.
