Paradoxical ventricular enlargement after successful shunting.
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.
