Takayasu's arteritis in a 69 year-old woman

Takayasu's arteritis and temporal arteritis share many clinical and pathological features. The most discriminatory feature between the two diseases is the age at onset; the mean age at onset of the disease was reported as being 26 years for Takayasu's arteritis and 69 years for temporal arteritis. Here we report a 69-year-old woman who presented with a weak right radial artery pulse. The ethnic background and the presence of vascular insufficiency of the right upper extremity and the absence of clinical signs such as shoulder stiffness and tender scalp indicate that her diagnosis is Takayasu's arteritis. It must be emphasized that the two conditions could be differentiated based on the clinical findings even in a patient as old as 69 years old.
