Myopathic camptocormia in a patient with levodopa unresponsive parkinsonism.

Camptocormia may be seen in Parkinson's disease. As no changes in paraspinal musculature are found, it is attributed to dystonia or extreme rigidity. However, several cases of parkinsonism and dropped head due to neck extensor myopathy have been reported. We report the first patient with levodopa unresponsive parkinsonism and camptocormia of muscular origin.
