AB  - PURPOSE To assess the usefulness of MR in the evaluation of patients with Horner&#039;s syndrome.PATIENTS AND METHODS We prospectively performed MR imaging in 33 patients with Horner&#039;s syndrome (13 preganglionic and 20 postganglionic) using a protocol specifically designed for pre- and postganglionic varieties of this syndrome. Assignment of patients to pre- or postganglionic categories was performed on the basis of pharmacologic testing.RESULTS Abnormalities in one-half of the patients with preganglionic Horner&#039;s syndrome included lateral medullary infarct, spinal cord/root disease, apical lung tumor, and paravertebral metastatic mass. Three of 20 patients with postganglionic Horner&#039;s syndrome had carotid artery dissection.CONCLUSION Routine scanning of patients who have postganglionic Horner&#039;s syndrome with cluster headaches was not helpful in our small series.
