A case of thoracic flexion myelopathy is reported in a 36-year-old man
. The patient had a history of gradually progressing transverse thorac
ic myelopathy. Conventional myelography in the neutral position failed
to reveal cord compression; however, a severe block of the dye column
was evident on studies in the flexed position. Excellent recovery fro
m this condition was obtained with posterolateral fusion of the thorac
ic spine in the neutral position.
