Giant cell arteritis (GCA) and polymyalgia rheumatica (PMR) can present with normal inflammatory markers. Clinical suspicion and biopsy are crucial for diagnosing GCA and PMR, even with normal labs.
Area of Science:
- Rheumatology
- Internal Medicine
- Pathology
Background:
- Giant cell arteritis (GCA) and polymyalgia rheumatica (PMR) are common rheumatological conditions in the elderly.
- These diseases are often associated with elevated inflammatory markers.
Purpose of the Study:
- To highlight the importance of clinical presentation in diagnosing GCA and PMR.
- To emphasize that normal inflammatory markers do not exclude GCA diagnosis.
Main Methods:
- Case report of a 61-year-old woman with symptoms of GCA and PMR.
- Diagnostic workup included laboratory tests and temporal artery biopsy.
- Treatment involved oral steroids and steroid-sparing agents.
Main Results:
- The patient presented with typical symptoms but normal inflammatory markers.
- Temporal artery biopsy confirmed GCA.
- The patient responded well to treatment, avoiding complications.
Conclusions:
- Normal inflammatory markers do not rule out GCA.
- Clinical presentation and pathological findings are critical for diagnosis.
- Early treatment initiation is vital for favorable outcomes in GCA and PMR.
