Man 63. years old. After he was attacked by cerebral apoplexy in 1963, the right spasmodic paresis remained with him and he has not been able to rise to his feet since about July in 1972.I suspected that he suffered from tumor of spinal cord but as a result of myelogram complete blocking were found at the tenth thoracic vertebra. Then, by tomography, I diagnosed his disease as spinal paralysis caused by the calcification of ligamentum flavum and I performed laminectomy. At the center of lamina synostosis of the calcified ligamentum fiavum and lamina was found.As I compared that view with the clinical symptom and also another example 11 in the Japanese paper, I found that those symptoms were presented, in most cases by old age and man, in all cases in thoracic vertebra. And as for the cause I thought that those symptoms in this case were caused by the calcification of ligamentum flavum, and the cause of the calcification is responsible to trauma and senior degeneration.
