Myasthenia gravis with concomitant severe paraspinal muscle degeneration and mitochondrial DNA4977 deletion.
Recent reports have discussed the many causes of dropped head syndrome and bent spine syndrome. We described a case of myasthenia gravis with concomitant severe degeneration of spinal muscle, mitochondrial DNA4977 deletion and sensorineural deafness. These associations were thought to be independent, however this is an important case to consider the etiology of bent spine syndrome.
