A 72-year-old female presents with a 2-month history of a new-onset, unilateral headache localized to her right temple. She also reports jaw pain when chewing (jaw claudication) and occasional transient visual disturbances in her right eye. On physical examination, her right temporal artery is tender, thickened, and non-pulsatile. Her erythrocyte sedimentation rate (ESR) is 90 mm/hr (normal <20 mm/hr). What is the most appropriate next step in her management?
- AInitiate high-dose corticosteroids immediately
- BPerform a lumbar puncture to evaluate for meningitis
- COrder a CT scan of the head to rule out intracranial pathology
- DRefer for urgent ophthalmologic evaluation
Show answer & explanationAnswer & explanation
Correct answer: A. Initiate high-dose corticosteroids immediately
The patient's age, new-onset unilateral headache, jaw claudication, transient visual disturbances, tender/thickened temporal artery, and significantly elevated ESR are highly suggestive of Temporal Arteritis (Giant Cell Arteritis). This condition is a medical emergency due to the risk of irreversible vision loss. Immediate initiation of high-dose corticosteroids is crucial to prevent this complication, even before a temporal artery biopsy (the gold standard for confirmation) is performed.
Why the other options are wrong
- B. There are no symptoms (e.g., fever, nuchal rigidity) to suggest meningitis, and a lumbar puncture is not indicated for Temporal Arteritis.
- C. While a CT scan might be ordered if other neurological symptoms were present, the classic presentation here points to Temporal Arteritis, and delaying treatment for imaging could lead to vision loss.
- D. While an ophthalmologic evaluation is important for assessing visual involvement, it should not delay the immediate initiation of corticosteroids, as vision loss can progress rapidly.
Temporal Arteritis (Giant Cell Arteritis)
Temporal Arteritis is a systemic vasculitis affecting medium and large arteries, primarily the temporal artery, characterized by headache, jaw claudication, and visual disturbances, with a high risk of permanent vision loss.
- Medical emergency due to risk of blindness.
- Symptoms: new headache, jaw claudication, visual changes, tender temporal artery.
- Elevated ESR is common.
- Requires immediate high-dose corticosteroids.
