Abstract
OBJECTIVE: Cerebral venous sinus thrombosis (CVST) is a rare but serious condition that can cause intracranial hypertension and hemorrhage. Common risk factors include thrombophilia and oral contraceptive use, but jugular Eagle syndrome-caused by an elongated styloid process compressing the internal jugular vein-is an uncommon yet clinically significant etiology. CASE PRESENTATION: A 44-year-old woman presented with severe right-sided headache, neck pain, and visual disturbances after cervical spine manipulation. Imaging revealed extensive CVST with venous congestion hemorrhage, and jugular Eagle syndrome was confirmed. Symptoms persisted despite anticoagulation, but her headache improved after successful endovascular thrombectomy. Styloidectomy was considered for long-term management. CONCLUSION: Jugular Eagle syndrome is a rare cause of CVST. Anticoagulation remains first-line, but thrombectomy may be required in refractory cases, and surgical styloidectomy should be considered for definitive management.
