[Roentgenographic changes of the skeleton in a case of tuberous sclerosis (morbus Bourneville-Pringle) (author's transl)].

Increasing sclerosis in the thoracolumbar spine has been followed up in a boy suffering from tuberous sclerosis. The earlist abnormality appearing as an irregular density in the radix of the posterior arch of the first lumbar vertebra has been detected at the age of one year. Until the ninth year of life the disease process has involved the vertebral column from T-8 to L-2. During the course roentgenograms revealed several diffuse areas of opacification with ill-defined outlines which tended to merge. As a rule all vertebrae were affected asymmetrically. Neither deformities of the vertebrae nor functional impairment of the axial skeleton have been found. Based on X ray appearance classification of characteristic and accessory bone abnormalities in tuberous sclerosis was discussed.
