  • Title: Differential diagnosis of pulsatile neck masses by Doppler color flow imaging.
    Author: Takeuchi Y, Numata T, Suzuki H, Konno A, Kaneko T.
    Journal: Ann Otol Rhinol Laryngol; 1995 Aug; 104(8):633-8. PubMed ID: 7639473.
    Abstract:
    A pulsatile neck mass (PNM) requires careful judgment in its evaluation, and it is difficult and inaccurate to diagnose a PNM only by physical examination, even though a thrill or bruit is present. Doppler colorflow imaging (DCI) was performed as an initial evaluation in nine patients with PNMs. Intravenous digital subtraction angiography, intra-arterial angiography, X-ray computed tomography, and magnetic resonance imaging were performed in selected cases. The DCI revealed seven vascular masses (three tortuosities of the common carotid artery, two tortuosities of the brachiocephalic artery, one pseudoaneurysm, and one traumatic arteriovenous fistula) and two nonvascular masses (one neurofibroma and one metastatic lymph node). The clinical diagnoses of all the vascular masses were defined by DCI. In nonvascular masses, fine-needle aspiration biopsy could be performed relatively safely and accurately by monitoring the feeding artery or the common carotid artery by DCI. This method was quite useful for the initial evaluation in the differential diagnosis of PNMs.
