RT Journal Article SR Electronic T1 Paradoxical ventricular enlargement after successful shunting. JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 1034 OP 1036 VO 15 IS 6 A1 C P Russo A1 L Hochhauser A1 J A Winfield YR 1994 UL http://www.ajnr.org/content/15/6/1034.abstract AB We present two cases of ventricular obstruction in which shunting of intracranial cysts resulted in the unexpected finding of ventricular enlargement. By imaging criteria this suggested shunt malfunction [corrected]; however, the clinical presentation dramatically improved. The probable mechanism for this diagnostic pitfall is discussed.
