Internal jugular vein aneurysm: a case report

Abstract

Venous aneurysms rarely present as a painless mass; they are usually symptomatic and present with pain, swelling, and sometimes, embolism. We present a 41-year-old man who presented with a painless swelling involving the right side of the neck. Examination of the neck revealed a soft, compressible, non-pulsatile and non-tender swelling above the right sternoclavicular joint. Doppler ultrasound showed a well-defined compressible cystic lesion measuring 4.2 × 1.9 cm causing indentation of the right sternocleidomastoid muscle. Further imaging studies confirmed the diagnosis of an aneurysmal dilation in the right internal jugular vein. An excisional biopsy of the aneurysm was performed using a longitudinal incision in the skin at the anterior border of the right sternocleidomastoid muscle and excisional venotomy was performed. Histopathological examination showed a cystic structure containing organizing blood clots surrounded by a thick fibrous wall. A follow-up neck ultrasound performed postoperative showed a patent internal jugular vein.

Internal jugular venous aneurysm—A report of two cases with literature review

“…[17][18][19][20] Complications such as spontaneous rupture, thrombophlebitis, thrombosis, and pulmonary embolism are rare. [5][6][7][8] When thromboses occur, they are more frequent in adults than in pediatric patients (17% vs 1.5%, respectively). 14 There has been only one case report that described a pulmonary embolism in the presence of IJVA thrombus with no other source.…”

“…The patient suffered no complications with no evidence of recurrence at 6 months of follow-up. He received no perioperative anticoagulation because of the low reported risk of thromboembolic complications [5][6][7][8].…”

Anatomical review of internal jugular vein cannulation

“…Duplication has not been reported to have physiological implications, but there are certain clinical implications such as plebectasias and aneurysms. An aneurysm is a vessel dilation that involves degeneration of all layers of the venous wall, while phlebectasia involves thinning of tunica media [6,15]. Duplications were found to be associated with phlebectasia in 46% of cases [86,116].…”

Thrombosed external jugular vein aneurysm mimics to a branchial cyst: A novel case from Iraq and review of the literature

“…Frequently the venous aneurysm has a fusiform shape, the saccular type is extremely rare [ 1 ]. Venous aneurysms are usually symptomatic such as pain and swelling, but they rarely are asymptomatic like a painless mass [ 3 ]. Venous aneurysm is mostly caused by infection, trauma, venous obstruction (portal hypertension, thoracic outlet syndrome or neoplasm) [ 2 ], or catheterization, but spontaneous venous aneurysm is extremely rare [ 4 ].…”
