Background: Eagle syndrome is a rare disorder whereby an elongated styloid process (ESP) causes not only some otolaryngological symptoms, but also cerebrovascular events caused by compression of the carotid artery. In recent years a syndrome, denominated as Eagle jugular syndrome, involving internal jugular vein (IJV) compression caused by an ESP has been proposed as a variation of Eagle syndrome. Clinical impact of the Eagle jugular syndrome on neurosurgical procedures has not been reported yet.
Case Description: We present a case of a 68-year-old woman who underwent microvascular decompression for hemifacial spasm of the left side and developed delayed intracranial hemorrhage on postoperative day 3. We also demonstrate that this patient developed ipsilateral IJV stenosis between an ESP and the muscle bundle of the rectus capitis lateralis with antero-flexion neck position, which would induce venous congestion in addition to surgical disruption of emissary vein.
Conclusion: This case is the first report demonstrating the association of an ESP with postoperative delayed intracranial hemorrhage. Our report elucidates the importance of the awareness among neurosurgeons of considering the ESP as an important bony anomaly, especially when planning for posterior fossa surgery.

Eagle syndrome is defined as an elongated styloid process (ESP) that compresses nearby vasculo-nervous structures. The vascular variant of Eagle syndrome can lead to neurological symptoms including syncope, transient ischemic attack, or stroke; however, it has also been associated with other atypical presentations, making its diagnosis challenging. This review aimed to depict the characteristics of patients with the symptomatic vascular variant of Eagle syndrome.

Vascular complications occurring in Eagle syndrome are seldom described. The aim of this study was to systematically review the occurrence, characteristics, and management outcomes of vascular complications occurring in Eagle syndrome. A systematic review was conducted with a search in several databases.

Background: Eagle syndrome, an uncommon condition, causes symptoms due to neural and/or vascular compression from an elongated styloid process or calcified stylohyoid ligament and can also complicate other planned surgical procedures.
Observations: A 42-year-old female with loss of balance, dizziness, and ataxic gait underwent cranial magnetic resonance imaging (MRI), revealing a right-sided Koos grade IV vestibular schwannoma. Initially, a retrosigmoid craniotomy for tumor resection was planned.

Article Synopsis
- - Eagle jugular syndrome (EJS) is linked to cerebrovascular disease caused by obstruction from an elongated styloid process, and this study investigates its potential relationship with de novo cerebral cavernous malformation (CCM) through a literature review from 1995 to 2023.
- - The review identified 14 EJS patients, with most showing increased intracranial hypertension, while 30 patients with de novo CCM developed their conditions often following complications like developmental venous anomalies and dural sinus thrombosis.
- - The findings suggest that venous congestion resulting from EJS may trigger the formation of de novo CCM, indicating EJS might serve as a warning sign for future CCM development, necessitating further research on their connection.

Eagle jugular syndrome is an uncommon condition caused by compression of an elongated styloid process onto the internal jugular vein. Its presentation is non-specific but may represent in severe clinical consequences including venous thrombosis and intracranial haemorrhage. Thorough understanding of local anatomy is important in understanding the pathogenesis and establishing the diagnosis.
