A variant of normal-pressure hydrocephalus simulating Pick's disease on computerized tomography. Report of two cases.

The authors present two cases of normal-pressure hydrocephalus that simulated Pick's disease radiographically and that were initially diagnosed as cortical atrophy. In both cases, Sylvian cisternoperitoneal shunts improved the clinical picture only temporarily, but ventriculoperitoneal shunting produced dramatic relief of all symptoms.
