Stroke and Temporal Arteritis: A Study of 6 Cases

Introduction: Though uncommon, ischaemic stroke due to temporal arteritis carries serious difficulties for diagnosis and subsequent management and requires a high level of suspicion.

Methods: We analysed a series of 6 patients with biopsy-proven temporal arteritis presenting with ischaemic stroke. We discuss clinical characteristics, difficulties of assessment, short- and long-term progression, treatment, and the usefulness of new diagnostic techniques.

Results: Our sample of 6 patients had a mean age of 68.3 years; 50% were women. The majority of patients showed systemic symptoms. Anterior and posterior circulation were affected similarly. MRI angiography, Doppler sonography, and PET-CT proved to be very useful for diagnosis and treatment. Mean follow-up time was 26 months. Clinical outcomes were far from good: 33% scored≥3 on the modified Rankin scale, including one death. Two patients had recurrent stroke despite treatment with full doses of corticosteroids, and 2 underwent angioplasty.

Conclusions: Stroke caused by giant cell arteritis is a serious and potentially severe condition which requires a high level of suspicion and early treatment with corticosteroids. New diagnostic techniques contribute to refining patient assessment and identifying the optimal treatment. Endovascular treatment may be a valid therapeutic option in selected patients.
