A text-book on diseases of the ear, nose and throat . areais a linear one along the surfaceunder the mucosa; if j)rojectingtherefrom, it is a knuckle of the ar-terial tube bulged out from the natu-ral course of the vessel. McBride ^has seen one case in which the pos-terior pillars themselves seemed topulsate, but an enlarged vessel wasfound immediately behind, and a systolic bruit was audible. In a secondcase a pulsating mass suspected to be an aneurism proved to be a a third case the i^atient suffered from a tinnitus compared to thehissing of escaping steam 5 in this instance many of the bodily arteriesvisibly x)ulsated, and the right radial ran an abnormal course. In thepharynx pulsation was visible on both sides at the junction of the pos-terior and lateral walls 5 on the right side the pulsation was communi-cated to the tonsil. In other instances, such as that reported by A. Brown Kelly, thepulsating vessel has been regarded as an abnormally tlexuous internalcarotid bulging towards the posterior pharyngeal walL Of course, an. Ascending pharyngeal arteries of abnormalsize. (Farlow.) 1 Edin. Med. Jour., December, 1896, p. 510. 488 VASCULAR ANOMALIES AXD PARASITIC DISEASES. 489 aneurism may occur, as in Eicliardsons case,^ in which the swelling ex-tended from a point a little to the right of the median line to the lateralwall of the pharynx, and from the level of the base of the tongue tothat of the lower edge of the i^alate. A bruit was audible, disappearingunder pressure on the common carotid. Eosenthal^ rex)orts a case of trueaneurism the size of a coffee bean located at the origin of the rightpharyngopalatine i)illar. Pulsation ceased on comj^ression of the rightcarotid. TJhl ^ has seen one case of traumatic aneurism of the descendingpalatine. In addition to pulsating arteries, j^ulsatiug veins have been noted bySanderson and Cresswell Baber. Xormally there exists on the posteriorand lateral pharyngeal walls a net-work of veins with meshes of unequalsiz
