Insights
This case highlights diagnostic confusion between giant cell arteritis and cluster headache in an elderly female. It emphasizes considering cluster headache in new or relapsing headaches, even in older women.
Area of Science:
- Neurology
- Vascular Neurology
- Headache Medicine
Background:
- Giant cell arteritis (GCA) and cluster headache (CH) are distinct neurological conditions presenting with head pain.
- Elderly patients, particularly women, are often underdiagnosed for certain headache disorders.
Observation:
- An elderly female with polymyositis presented with new-onset temporal headache initially diagnosed as GCA.
- The patient's subsequent clinical course was typical of cluster headache.
Findings:
- This case demonstrates significant diagnostic overlap and potential confusion between GCA and CH.
- Clinical presentation can be misleading, necessitating a broad differential diagnosis.
Implications:
- Cluster headache should be considered in the differential diagnosis of new-onset or relapsing headaches in the elderly, including women.
- Awareness of CH in elderly females is crucial, challenging historical perceptions of its lower prevalence in this demographic.
- Accurate diagnosis is essential to guide appropriate management and prevent complications associated with misdiagnosis.
Abstract:
We describe an elderly female patient with known polymyositis who presented with new onset temporal headache that was diagnosed as giant cell arteritis but subsequently had a typical clinical course of cluster headache. This case illustrates the potential for diagnostic confusion between giant cell arteritis (GCA) and cluster headache (CH) and the need to consider CH as a potential differential diagnosis in those newly presenting with headaches, even in the elderly, and relapsing headaches in subjects with a diagnosis of GCA. Importantly, this needs to include female patients, a group historically thought to be much less likely to develop CH.
