Neurologic signs vary from no findings to progressive neurologic loss usually involving the legs, bladder, and anal sphincter. Roentgenographic examination of the spine shows widening of the interpedicular distance, absent laminae and spinous processes, and various fusion anomalies of the vertebrae. Computed tomographic studies with metrizamide injected into the subarachnoid space (a myelogram) outlines the lipoma and its attachment to the spinal cord.
