Summary
A rare case of generalized giant cell arteritis led to unexpected death. Autopsy revealed coronary artery involvement and myocardial infarction, highlighting a severe complication of this vasculitis.
Area of Science:
- Cardiovascular Pathology
- Rheumatology
- Systemic Vasculitis
Background:
- Giant cell arteritis (GCA) is a systemic vasculitis primarily affecting elderly individuals, typically involving cranial arteries.
- Polymyalgia symptoms can occur in GCA, but classic signs of temporal arteritis may be absent.
- Corticosteroid treatment, like prednisone, is standard for GCA, but efficacy can vary.
Observation:
- An autopsy was performed on a 74-year-old woman with a history of polymyalgia and absent typical temporal arteritis symptoms.
- Despite prednisone treatment, polymyalgic pain persisted, suggesting an atypical presentation or progression.
- Autopsy revealed widespread giant cell arteritis affecting cranial, aortic, ileal, and coronary arteries.
Findings:
- Histological examination confirmed granulomatous inflammation with giant cells, characteristic of GCA.
- Thrombotic occlusion of the left anterior descending coronary artery branch was identified.
- Myocardial infarction resulted from the coronary artery occlusion.
Implications:
- This case underscores that giant cell arteritis can present atypically, without classic cranial symptoms.
- Coronary artery involvement in GCA, though uncommon, can lead to severe cardiac events, including sudden death.
- The findings emphasize the importance of considering systemic vasculitis in elderly patients with unexplained pain and potential cardiovascular complications.
