[Syringomyelobulbia associated with cervical spondylosis. Pathophysiology and therapeutic implications].
Spinal spondylosis is rarely implicated in syringomyelia. We report the case of a 70-year-old patient with a 10-year history of gait disturbance; constrictive pain of lower limbs and urinary incontinance. Physical examination disclosed spastic tetraparesis. In the upper limbs, deep tendon reflexes were abolished, with hyposthesia and hands amyotrophy. Brain and cervical MRI showed syringomyelobulbia with cervical spondylotic myelopathy. Extensive cervical laminectomy induced a mild clinical improvement. A second MRI performed 6 months after surgery depicted a complete disappearance of the bulbo-medullar cavitation with secondary atrophy. Extradural spondylotic compression of the spinal cord should be firmly considered as an etiology of syringomyelia. A purely extradural decompression could be sufficient to induce regression of the medullary cavitation.
