RT Journal Article SR Electronic T1 Raeder syndrome: MR appearance. JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 1121 OP 1123 VO 13 IS 4 A1 M Castillo A1 L Kramer YR 1992 UL http://www.ajnr.org/content/13/4/1121.abstract AB A 40-year-old woman presented with symptoms compatible with Raeder syndrome. MR demonstrated narrowing of the left cavernous carotid artery. The high cervical portion of the left internal carotid artery was not identified. Angiography confirmed the narrowing of the cavernous carotid artery and showed marked and irregular stenosis of the distal cervical internal carotid artery. Involvement of the left sympathetic plexus and of ipsilateral cavernous sinus arteries is believed to have been the cause of the Raeder syndrome in this patient.
