Internal jugular vein aneurysm in an adult: diagnosis on non-invasive imaging

Unveiling the uncommon: Giant internal jugular vein aneurysm in a neurofibromatosis patient: A case report

Neurofibromatosis Type 1 (NF1) is a rare autosomal dominant disorder that has a wide array of clinical manifestations. NF1 Vasculopathies constitute 0.4% to 6.4% of the findings and they often develop in the arterial circulation while venous involvement is rare. We present a case of a 73-year-old male with NF1 with an incidental finding of right neck swelling for 2 months. Different radiological modalities were performed, identifying the lesion as an internal jugular vein aneurysm. The patient was managed conservatively as he was asymptomatic in relation to the swelling. NF1 venous vasculopathies are rare but they have detrimental consequences such as rupture and severe hemorrhage in view of the fragility of the aneurysmal wall and the infiltration of the neurofibroma into the vessel. Hence, high clinical suspicion and selective imaging and follow-up is advisable for physicians.

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

Internal jugular venous aneurysm (IJVA) is a rare entity that usually remains asymptomatic with only rare complications. We report two cases of IJVA. Both patients presented with a palpable soft tissue mass in the neck and were found to have IJVA on imaging with associated lymphadenopathy. In both cases, the aneurysms and involved lymph nodes were resected, with the jugular vein being primarily reconstructed. There are only a few case reports involving IJVA, and treatment guidelines are not well established. Whereas nonoperative management is frequently chosen, the most common indication for surgery is cosmetic; both management options have favorable outcomes.

Internal jugular phlebectasia: A systematic review

Background:

Internal jugular phlebectasia (IJP), the abnormal dilatation of internal jugular vein, is generally considered a benign anomaly. However, because IJP is uncommon, little is known about its natural history, and currently, no consensus on the best treatment modality is available.

Methods:

The purpose of this article is to conduct a systematic review of available literature on recently reported IJP cases to understand the main characteristics of IJP and its most frequent therapeutic approaches. Following the preferred reporting items for systematic reviews and meta-analyses guidelines, literature search for IJP cases was conducted in the COCHRANE, PUBMED, EBSCOHOST, SCOPUS, OVID, and SCIELO databases.

Results:

A total of 97 original articles were found, with a total of 247 IJP cases reported including both pediatric and adult patients.

Conclusions:

To the best of our knowledge, this study is the largest systematic review analyzing all the reported cases of IJP. IJP is considered by most authors as a benign abnormality that predominantly affects the right jugular vein. It is most commonly diagnosed in children. At present, conservative treatment is preferred for pediatric but not for adult patients. Multicenter randomized prospective studies are required to further understand this rare anomaly.
