Abstract
Introduction
Spinal cord injury (SCI) with atlantoaxial dislocation (AAD) is often fatal. We present the case of a resuscitated patient with AAD and traumatic subarachnoid hemorrhage (SAH) at the craniovertebral junction (CVJ).
Case presentation
We present the case of an 84-year-old man who suffered an observed cardiopulmonary arrest. Cardiopulmonary resuscitation was initiated and spontaneous circulation returned. In the emergency room, the patient’s Glasgow Coma Scale was 3 (E1V1M1). No spontaneous respiration was noted. Neuroimaging revealed SAH at the CVJ. Contrast-enhanced computed tomography (CT) revealed a vessel running through the left C2/3 intervertebral foramen into the spinal canal. The ventral space of spinal cord revealed contrast enhancement. Angiography revealed extravasation from the spinal branch of the left vertebral artery, without venous filling. It did not appear to be a vascular malformation with an arteriovenous shunt, but rather a traumatic laceration of the artery. Plain CT and CT angiography suggested AAD. Magnetic resonance imaging revealed injury to the medulla oblongata and upper cervical spinal cord, with AAD and retrodental subligamentous hemorrhage. We embolized the branch of the left vertebral artery and performed a C1 laminectomy. The patient moved his extremities postoperatively.
Discussion
This was a case of injury to the medulla oblongata and upper cervical spinal cord due to AAD with SAH. This is the first report of resuscitated case of traumatic AAD with SAH in the CVJ. Traumatic AAD should be included in the differential diagnosis in case of SAH in CVJ, which may be misdiagnosed as intrinsic SAH.
