To assess the usefulness of MR in the evaluation of patients with Horner's syndrome. We prospectively performed MR imaging in 33 patients with Horner'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. Abnormalities in one-half of the patients with preganglionic Horner's syndrome included lateral medullary infarct, spinal cord/root disease, apical lung tumor, and paravertebral metastatic mass. Three of 20 patients with postganglionic Horner's syndrome had carotid artery dissection. Routine scanning of patients who have postganglionic Horner's syndrome with cluster headaches was not helpful in our small series.
