AbstractExternal jugular vein aneurysm with thrombosis presenting as neck swelling is a rare clinical entity and rarely encountered in routine clinical practice in otorhinolaryngology. Keywords: Saccular aneurysm; External jugular vein; ThrombosisWe present a case of a 52-year-old female with external jugular vein aneurysm presenting as a neck mass. Ultrasound of the neck and CT showed saccular dilation of the external jugular vein with thrombosis within the aneurysm. Saccular aneurysm of the external jugular vein is very uncommon and can lead to thrombotic complications with serious consequence.Physical examination revealed a 4 × 3 cm soft, round, non-pulsatile, fluctuant swelling on the left sternocleidomastoidien region.A 52-year-old woman presented at our department with complaints of progressive swelling on left sternomastoidien region for 3 years. There was no history of preceding trauma, or cannulation of the vein and infusion of fluid for extended period .and there was no history of difficulty in swallowing, change in voice or any nasal symptoms.The overlying skin over the swelling had no signs of inflammation. Swelling was mobile in horizontal plane. There was mild increase in the size of the swelling during Valsalva manoeuvre and during laughing. The swelling was mildly compressible and slip sign was negative. No bruit could be detected on auscultation over the swelling. There was no other swelling in the neck or on other parts of the body. Nasofibroscopy and rhinocavoscopy were normal.Ultrasonography of the neck reported a thin-walled cystic mass on the left side abutting the left external jugular vein, Contrastenhanced computed tomography scan of the neck showed a focal area of dilatation of the left external jugular vein and enhancing oval-shaped swelling arising from the external jugular vein (Figure 1).
