title: [Radiologic evaluation of an isolated vertebral hemangioma].
abstract: CT scan and M.R.I. features have been evaluated in case of compressive (H.V.C.) and asymptomatic (H.V.A.) vertebral hemangiomas. The main datas observed in H.V.C. are: 1) thoracic localization; 2) whole vertebral body involvement; 3) extension to the pedicles; 4) irregular trabeculation; 5) swelling of bone contours with 6) epidural and perivertebral extension. H.V.C. always exhibit at least three of these six datas while H.V.A. are associated with 2 or less. Also H.V.C. frequently present intravertebral contrast enhancement on CT and low signal intensity on T1 weighted and high signal intensity on T2 weighted M.R.I.
