<p>The pulsatile area of the supra clavicular fossa was examined using high resolution transducer on gray scale and colour Doppler settings. There is mild dilatation of the innominate artery, measuring 15 mm in diameter and is seen projecting in to the supra-clavicular fossa. However, it is of normal wall thickness, colour flow and wave form.</p><p>Its terminal branches (subclavian and common carotid arteries) are of normal caliber, colour flow and wave form.</p><p>There is no evidence of a mass lesion or fluid collection.</p><p>Conclusion: Findings suggest an ectatic innominate artery with high bifurcation in to the supra-clavicular fossa.</p>
