Clinical Procedure: —
Specialty: Neurology • Neurosurgery • Sports Medicine
Objective:
Rare disease
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.
