    In this 1-Minute Video, Dr. Vivek Patel reviews the neurobiology behind Horner syndrome. Physicians quickly consider this disease when observing a combination of miosis, anhidrosis and ptosis, but Horner can be caused by an interruption along the first, second, or third order neuron in the sympathetic pathway. Dr. Patel emphasizes that any patient presenting with painful Horner syndrome is considered to have a carotid dissection until proven otherwise. Since urgent neuroimaging is necessary, CT or MR angiograph are excellent for vascular pathology but require imaging from the apex of the lung to cervical villus and must include the neck. If the patient has a soft tissue injury, MRI may be preferable; however, this is an emergency that requires partnering up with a neurologist.
