[Vertebral hemangioma with extradural spinal cord compression. Clinico-radiologic and NMR findings].

A haemangioma extending from the first thoracal vertebra into the extradural spinal canal presented clinically as slowly progressive incomplete cord compression. Radiographic, myelographic, and CT findings are demonstrated and an additional lumbar vertebral haemangioma was found. The study of magnetic resonance imaging (MRI) done by spin-echo technique indicated that signal intensities within the vascular malformation measured in various recovery (TR) and echo times (TE) are largely the result of different blood flow velocities.
