Summary
A rare case of Takayasu-type aortitis led to fatal aortic dissection and hemopericardium in a 57-year-old woman. Careful histologic examination is crucial for diagnosing aortic root disease.
Area of Science:
- Cardiovascular Pathology
- Rheumatology
- Vascular Surgery
Background:
- Aortic dissection is a life-threatening condition often associated with hypertension or connective tissue disorders.
- Aortitis, inflammation of the aorta, can predispose to aortic complications, but its role in acute aortic dissection is less understood.
- Takayasu arteritis is a rare form of large vessel vasculitis primarily affecting the aorta and its branches.
Observation:
- A 57-year-old woman presented with maxillary pain radiating to the chest, rapidly progressing to death within 12 hours.
- CT imaging revealed ascending aorta dissection with hemopericardium.
- Autopsy confirmed a tear proximal to the brachiocephalic artery ostium, a dissecting flap, and hemopericardium.
Findings:
- Histological examination showed zonal medial necrosis, chronic inflammation, and fibrosis.
- The findings were consistent with granulomatous necrotizing aortitis of Takayasu type.
- Aortitis was identified as the underlying cause of the aortic dissection.
Implications:
- This case highlights a rare presentation of Takayasu arteritis leading to aortic dissection.
- Emphasizes the importance of thorough histologic evaluation in aortic root pathologies.
- Underscores the need for early recognition and management of aortitis to prevent catastrophic vascular events.
