RT Journal Article SR Electronic T1 Brown-Séquard Syndrome Secondary to Spontaneous Bleed from Postradiation Cavernous Angiomas JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 1989 OP 1990 DO 10.3174/ajnr.A1158 VO 29 IS 10 A1 M.S. Mathews A1 W.W. Peck A1 M. Brant-Zawadzki YR 2008 UL http://www.ajnr.org/content/29/10/1989.abstract AB SUMMARY: The spontaneous occurrence of acute Brown-Séquard syndrome is an extremely rare event, with most reported cases being secondary to spontaneous epidural hematomas and spinal cord ischemia. We report a rare case of Brown-Séquard syndrome from spontaneous intraspinal hemorrhage in a patient with multiple cavernous angiomas in the spinal cord secondary to craniospinal radiation in childhood. Postulated mechanisms leading to the condition include postradiation molecular changes and venous occlusion.
