Abstract

To report a case of Horner's syndrome and dissection of the internal carotid artery after chiropractic manipulation of the neck. Case report. A 44-year-old woman with no prior ocular or vascular history presented with severe right-sided head and neck pain, ptosis, and miosis following chiropractic treatment for a strained right shoulder muscle. Magnetic resonance angiography of the neck and brain revealed a dissection of the right internal carotid artery as well as a suggestion of subtle dissection in the right vertebral artery. No significant brain abnormalities were noted on magnetic resonance imaging. Pharmacological testing was consistent with preganglionic oculosympathetic damage. Acute, painful Horner's syndrome as a manifestation of vascular dissection may be associated with chiropractic manipulation of the neck.
