Spinal accessory nerve cavernous malformation
Journal of Clinical Neuroscience, 2010We present the first reported case of a spinal accessory nerve cavernous malformation. A 54-year-old Caucasian male presented with a several-year history of progressive, vague bilateral upper and lower extremity paresthesias and pain. MRI of the spine revealed a heterogenously enhancing mass in the dorsal aspect of the spinal canal at the level of the ...

Extracranial Spinal Accessory Nerve Injury
Neurosurgery, 1993Eighty-three consecutive patients with extracranial accessory nerve injury seen over a 12-year period are reviewed. The most common etiology was iatrogenic injury to the nerve at the time of previous surgery. Such operations were usually minor in nature and often related to lymph node or benign tumor removal.

Spinal Accessory Nerve Lesions
Seminars in Neurology, 2009The spinal accessory nerve, primarily a motor nerve, innervates the sternocleidomastoid and trapezius muscles. Proximally, lesions can occur intracranially at the skull base or just outside the jugular foramen producing ipsilateral weakness of trapezius and sternocleidomastoid muscles; or distally, in the posterior neck triangle causing trapezius ...

Clinical Orthopaedics and Related Research, 1975
In 7 cases of peripheral lesion of the spinal accessory nerve 4 were produced by malignancy, two by iatrogenical resection of lymph nodes, one by an en bloc dissection of the neck for arteriovenous malformation. Incapacity following the injury is quite marked and includes weakness of the sternomastoid and trapezius muscles, as well as pain presumably ...

Schwannoma of the spinal accessory nerve
Journal of Clinical Neuroscience, 1998The authors report a case of a schwannoma originating from the spinal root of the accessory nerve. The patient was a 40-year-old woman with chronic headache and blurred vision. A neurological examination failed to reveal any abnormal findings except for papilloedema.

Postirradiation neuromyotonia of spinal accessory nerves
Neurology, 2011Neuromyotonia is a rare complication of radiation therapy.1 Most reported cases involve oculomotor muscles1,2 and occur months to decades after radiation therapy. Neuromyotonia is characterized by transient involuntary tonic contractions, which occur either spontaneously or are triggered by movements, with delayed relaxation of affected muscles.3,–,5 ...

Stretch‐induced spinal accessory nerve palsy
Muscle & Nerve, 1988AbstractLeft spinal accessory nerve palsy occurred in a young man when he quickly turned his head to the right while his shoulders were pulled down by heavy hand‐held objects. Electrophysiologic studies demonstrated partial axonotmesis of the spinal accessory nerve branches innervating the sternocleidomastoid and upper and middle trapezius and complete

Spinal accessory nerve (SAN) injuries can be idiopathic or iatrogenic. Providers who understand the essential anatomy of the SAN can direct the history, physical exam, and ancillary studies to localize the lesion, while considering the differential diagnosis.

Journal of Manual & Manipulative Therapy, 1996
AbstractThis 46 year old female sustained a right humeral Holstein fracture without radial nerve complications related to a ski fall. She also sustained a left spinal accessory nerve traction injury which was undiagnosed until six weeks post-fracture. There was significant denervation of the left upper, middle and lower trapezius muscles.
