Giant cell arteritis causes recurrent posterior circulation transient ischemic attacks which respond to

|January 1, 1987
Summary
Giant cell arteritis can cause posterior circulation transient ischemic attacks (TIAs). Prompt corticosteroid treatment effectively resolved symptoms in a patient, highlighting a treatable cause of TIAs.
Area of Science:
- Neurology
- Rheumatology
- Vascular Medicine
Background:
- Posterior circulation transient ischemic attacks (TIAs) can be challenging to manage, especially when unresponsive to standard anticoagulation.
- Giant cell arteritis (GCA) is a systemic vasculitis that can affect large and medium-sized arteries, potentially leading to ischemic events.
Observation:
- A 67-year-old male experienced recurrent, diverse posterior circulation TIAs despite optimal anticoagulation therapy.
- Markedly elevated erythrocyte sedimentation rate (ESR) raised suspicion for GCA.
- Temporal artery biopsy confirmed the diagnosis of giant cell arteritis.
Findings:
- Corticosteroid therapy led to rapid and sustained resolution of the patient's posterior circulation TIA symptoms.
- The patient's clinical presentation and response to treatment strongly implicated GCA as the underlying cause of TIAs.
Implications:
- Giant cell arteritis should be considered in the differential diagnosis of patients presenting with posterior circulation TIAs, particularly those with elevated inflammatory markers.
- Early diagnosis and treatment of GCA with corticosteroids may prevent further ischemic events and improve outcomes in affected individuals.
- This case underscores the potential for GCA to manifest as TIAs and highlights the efficacy of immunosuppressive therapy in managing such neurological complications.
