[A very frequent radiologic sign in dorsolumbar localization of chordoma: increase in the interpeduncular distance].
The X-ray picture of 11 cases of chordoma of the thoraco-lumbar spine at the Tumors Centre of the Rizzoli Orthopaedic Institute is studied. In 7 cases an increase in the interpeduncular distance of the affected vertebrae was noticed. The high incidence of this radiologic sign, never reported previously in the literature, represents a semeiologic element of great importance in the diagnosis of this neoplasm. The ways of measurement are then indicated and the significance of this report is stressed.
