title: Type 3 takayasu arteritis diagnosed by parvus-tardus renal Doppler signal modulation.
abstract: Takayasu's arteritis is known to cover the youngest age group in the etiology of secondary hypertension. The type 3 pattern is rare and involves the thoraco-abdominal aorta and its main abdominal branches. Here, we present the imaging results of a patient who had been followed up for systemic arterial hypertension and was diagnosed with Takayasu's arteritis type 3 by CT and MR angiography following bilateral detection of a parvus-tardus Doppler signal modulation in the renal arteries. We discuss the differential diagnoses that should be considered when observing a tardus-parvus Doppler signal. © 2017 Wiley Periodicals, Inc. J Clin Ultrasound 45:612-615, 2017.
