Takayasu arteritis is an inflammatory and stenotic disease of medium and large sized arteries characterized by a strong predilection for the aortic arch and its branches. We present the case of an 18 years old woman who was referred from dermatology department with the complaints of fever and drug allergy . On routine check up she was found to have fever , peeling and scaling of palmar skin , pedal edema and hypotension and was managed initially for septic shock. Takayasu arteritis was suspected on detailed examination . A thorough cardiovascular examination including blood pressure recording from the lower limb revealed hypertension , feeble upper limb pulses but good volume lower limb pulses . Hence the Initial Hypotension in our patient proved to be Pseudo–hypotension. It is recommended that in such cases additional ankle pressure measurement should also to done to avoid misdiagnosis regarding status of the blood pressure.
