Management of Unilateral Pulsatile Temporal Headache

Diagnostic Considerations

The American Academy of Neurology suggests that unilateral pulsatile temporal headache is consistent with migraine without aura, and recommends initiating acute treatment with NSAIDs or acetaminophen as first-line therapy, escalating to triptans if these fail, while simultaneously ruling out giant cell arteritis if the patient is over 50 years old 1, 2
The International Headache Society recommends verifying the patient meets ICHD-3 criteria to confirm migraine without aura, which includes at least 5 lifetime attacks lasting 4-72 hours when untreated, at least 2 pain characteristics, and at least 1 associated symptom 1, 3, 5

The American Headache Society recommends initiating NSAIDs (ibuprofen, naproxen) or acetaminophen for mild-to-moderate attacks, limiting use to ≤2 days per week or maximum 10 days per month to prevent medication-overuse headache 6, 2
The European Neurological Society suggests that if NSAIDs fail or pain is moderate-to-severe, triptans (sumatriptan, rizatriptan, or other 5-HT1B/D agonists) should be prescribed, which eliminate pain in 20-30% of patients by 2 hours 2

The American Academy of Neurology recommends initiating preventive medications if attacks occur frequently enough to impair quality of life, acute treatments are ineffective or contraindicated, or patient is at risk for medication-overuse headache 1, 2
The International Headache Society suggests that preventive options include antihypertensives (propranolol), antiepileptics, antidepressants, CGRP monoclonal antibodies, or onabotulinumtoxinA, which reduce migraine by 1-3 days per month relative to placebo 1, 2

The American Headache Society recommends emergency admission if any red flag is present, patient is unable to self-care without help, or suspected spontaneous intracranial hypotension (orthostatic headache pattern) 2, 5, 6
The European Neurological Society suggests urgent neurology referral (within 48 hours) if suspected spontaneous intracranial hypotension (orthostatic headache pattern), and routine neurology referral (2-4 weeks) if diagnosis is uncertain after initial evaluation, first-line treatments fail, or suspected primary headache disorder requiring specialist management 2, 3, 6
