Hemorrhagic shock is the most common reason to explain the inability to feel pulse in a trauma patient. However, clinicians should always suspect atypical causes for differential pulses in this population and Takayasu′s arteritis (TA) is one such example. We report a case of aorto-arteritis in a patient who presented with trauma and was later diagnosed with TA. She had blood pressure discrepancy between upper and lower limbs noted upon her initial trauma evaluation.
