Abstract
Neurologists encounter a range of neurological disorders triggered by head and neck movement, reflecting an array of underlying pathologies and producing diverse symptoms. This article provides a practically orientated review of 14 disorders and how to diagnose and manage them, including common disorders such as benign paroxysmal positional vertigo and uncommon entities such as arterial compression syndromes leading to stroke or syncope, mobile intraventricular masses and medication withdrawal states. The article considers atypical scenarios including unusual manifestations and important mimics and discusses controversial entities, as well as the risk of misattributing symptoms based on incidental imaging abnormalities. Guidelines are referenced where they exist, while in rarer situations, approaches taken in published cases are described, with the acknowledgement that management decisions are at the clinician's discretion.

Wang S, Bi Y, Chen Y. Bilateral Bow Hunter Syndrome Associated with Loss of Cervical Physiological Curvature. AMERICAN JOURNAL OF CASE REPORTS 2024; 25:e942609. [PMID: 38605499 PMCID: PMC11020505 DOI: 10.12659/ajcr.942609] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2023] [Revised: 02/28/2024] [Accepted: 02/08/2024] [Indexed: 04/13/2024]
Abstract
BACKGROUND Bow hunter syndrome is a rare disease that is often overlooked. It presents with complex and variable clinical symptoms and causes, making diagnosis and treatment challenging. This case report focuses on a young patient with bilateral bow hunter syndrome, possibly caused by the loss of cervical physiological curvature. The aim is to enhance understanding and awareness of the disease. It is important to consider the possibility of bow hunter syndrome in young patients with long-term poor neck posture and symptoms such as dizziness, nausea, vomiting, and neck rotation-related symptoms. In such cases, thorough examination of posterior circulation hemodynamics and vascular morphology is recommended. CASE REPORT A 25-year-old woman was admitted to the hospital mainly because of "dizziness for 10 hours." The dizziness was aggravated when the right side of the neck was turned and the body position changed. This was accompanied by visual rotation, nausea, and vomiting. Bow hunter syndrome was diagnosed based on the clinical symptoms and hemodynamic examination of the posterior circulation. The patient was given a cervical collar to limit excessive twisting of the neck and instructed to avoid large-angle deflection of the neck after discharge. During the 3-month follow-up, no characteristic symptoms (such as dizziness) reappeared. CONCLUSIONS Bow hunter syndrome is a rare clinical posterior circulation compression syndrome with complex etiology. This case suggests that the simple disappearance of cervical curvature may be related to the occurrence of bow hunter syndrome. The dynamic monitoring of blood flow by color Doppler ultrasound and transcranial Doppler in different head positions provides clear clues to suspected bow hunter syndrome. With the help of computed tomography angiography, the diagnosis of bow hunter syndrome may be obtained by noninvasive examination.

Abstract
There are many lesions that cause compression of nerves and vessels in the head and neck, and they can often be overlooked in the absence of adequate history or if not suspected by the radiologist. Many of these lesions require a high index of suspicion and optimal positioning for imaging. While a multimodality approach is critical in the evaluation of compressive lesions, an MRI utilizing high-resolution (heavily weighted) T2-weighted sequence is extremely useful as a starting point. In this review, we aim to discuss the radiological features of the common and uncommon compressive lesions of the head and neck which are broadly categorized into vascular, osseous, and miscellaneous etiologies.

Abstract
Hidden bow hunter's syndrome (HBHS) is a rare disease in which the vertebral artery (VA) occludes in a neutral position but recanalizes in a particular neck position. We herein report an HBHS case and assess its characteristics through a literature review. A 69-year-old man had repeated posterior-circulation infarcts with right VA occlusion. Cerebral angiography showed that the right VA was recanalized only with neck tilt. Decompression of the VA successfully prevented stroke recurrence. HBHS should be considered in patients with posterior circulation infarction with an occluded VA at its lower vertebral level. Diagnosing this syndrome correctly is important for preventing stroke recurrence.

A case report of Bow Hunter's syndrome with intravascular ultrasound showing changing significant severe stenosis of the left vertebral artery associated with turning left. Eur Heart J Case Rep 2024; 8:ytad639. [PMID: 38213868 PMCID: PMC10783641 DOI: 10.1093/ehjcr/ytad639] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2023] [Revised: 12/07/2023] [Accepted: 12/18/2023] [Indexed: 01/13/2024]
Abstract
Background Bow Hunter's syndrome is vertebral basilar artery insufficiency caused by mechanical occlusion of the vertebral artery during head rotation. This is often due to the formation of osteophytes, herniated discs, cervical spondylosis, or tumours. However, whether the contralateral vessel is organically stenotic is not well known. Case summary A 79-year-old man was referred to our department for a close examination of syncope because the transient loss of consciousness occurring when he was made to turn his head to the left was reproducibly induced and recovered when his face was returned to the normal position. The carotid massage did not induce significant bradycardia or hypotension bilaterally, and Holter electrocardiography, echocardiography, head-up tilt test, coronary angiography, and an acetylcholine stress test showed no obvious abnormalities. A 3D CT angiography was performed to investigate the possibility of vertebrobasilar artery insufficiency, as C3/4 cervical spondylosis, and the left vertebral artery was compressed by the C4 superior process osteophyte, indicating hypoplasia of the contralateral vertebral artery. Vertebral artery angiography and intravascular ultrasound (IVUS) showed moderate stenosis of the left vertebral artery, and IVUS showed a half-circumferential calcified lesion. Compared to the midline position, the stenosis worsened at the site of compression and drainage when the patient turned left downward, and a diagnosis of Bow Hunter's syndrome was made. Discussion Bow Hunter's syndrome is characterized by vertebrobasilar insufficiency. Intravascular ultrasound clearly showed that the lesion was not only stenotic due to compression but also had plaque growth due to continuous mechanical stimulation.

Abstract
BACKGROUND Cerebrovascular disorders are an important cause of morbidity and mortality in children. The acute care of a child with an ischemic or hemorrhagic stroke or cerebral sinus venous thrombosis focuses on stabilizing the patient, determining the cause of the insult, and preventing secondary injury. Here, we review the use of both invasive and noninvasive neuromonitoring modalities in the care of pediatric patients with arterial ischemic stroke, nontraumatic intracranial hemorrhage, and cerebral sinus venous thrombosis. METHODS Narrative review of the literature on neuromonitoring in children with cerebrovascular disorders. RESULTS Neuroimaging, near-infrared spectroscopy, transcranial Doppler ultrasonography, continuous and quantitative electroencephalography, invasive intracranial pressure monitoring, and multimodal neuromonitoring may augment the acute care of children with cerebrovascular disorders. Neuromonitoring can play an essential role in the early identification of evolving injury in the aftermath of arterial ischemic stroke, intracranial hemorrhage, or sinus venous thrombosis, including recurrent infarction or infarct expansion, new or recurrent hemorrhage, vasospasm and delayed cerebral ischemia, status epilepticus, and intracranial hypertension, among others, and this, is turn, can facilitate real-time adjustments to treatment plans. CONCLUSIONS Our understanding of pediatric cerebrovascular disorders has increased dramatically over the past several years, in part due to advances in the neuromonitoring modalities that allow us to better understand these conditions. We are now poised, as a field, to take advantage of advances in neuromonitoring capabilities to determine how best to manage and treat acute cerebrovascular disorders in children.

Abstract
RATIONALE Fu's subcutaneous needling (FSN) is effective for cervicogenic dizziness (CGD), which is often a result of vascular problems. Here, we attribute the positive treatment effect of FSN for CGD to improvements in vascular problems. PATIENT CONCERN Two patients were experiencing low quality of life due to reproducible dizziness. DIAGNOSIS Two patients with cervical spine disorder, presented with neck pain and reproducible dizziness. Other causes of dizziness were excluded. INTERVENTIONS Case 1 received 1 session of FSN treatment, while case 2 received 3 sessions of FSN treatment in a month. OUTCOMES The dizziness and neck pain experienced by both patients instantly improved significantly after FSN treatment, and the luminal diameter of the vertebral artery (VA) measured by carotid and VA ultrasound enlarged simultaneously up to 1.29-fold and 1.09-fold for both cases. According to the Hagen-Poiseuille equation, the blood flow volume increased 2.77-fold and 1.43-fold, respectively. Case 2 recovered from CGD with 1.19-fold VA luminal diameter increment and about 2.01-fold increase of blood flow volume in a month. LESSONS Subcutaneous stretching provides a safe, convenient and immediate solution to CGD, and supports the diagnosis and treatment of CGD under carotid and VA ultrasound. This study suggests that stretching subcutaneously can influence adjacent VA, which may also help improve some cerebrovascular diseases.
