Acute Unilateral C5 Nerve Root Palsy Caused by Venous Engorgement Associated with the Tortuous Vertebral Artery: A Case Report
Received: 31 July 2019   • Revised: 27 September 2019   • Accepted: 21 October 2019
The existence of tortuous vertebral artery as a result of developmental anomaly is very rare condition. Previously, there were case reports that tortuous vertebral artery was associated with headache or cervical pain, however there was no report that was related to motor weakness by cervical root compression caused by venous engorgement associated with tortuous vertebral artery. This case study demonstrates a case of a patient with proximal muscle weakness in the left upper extremity due to venous engorgement associated with tortuous vertebral artery, and C5 nerve root palsy caused by it. We will discuss the cause of the disease and suggest effective treatment for it.
Key Words: tortuous vertebral artery, venous engorgement, C5 nerve root palsy
