A retrospective analysis at a tertiary referred center was done to determine the frequency with which an acute @entity911 state is caused by a @entity64 and to evaluate the usefulness of performing computed tomography in this setting. We reviewed 127 neurology consultations requested for @entity1 presenting with acute and apparently isolated mental status changes. The mean age was 62. Nine of 127 (7%) were thought to have suffered mental status changes as a result of an @entity64 : one @entity510 and eight @entity385 . There was no @entity1779 . The locations of the @entity1188 were right frontoparietal (four @entity1 ), bilateral occipital (two @entity1 ), bilateral frontal (two @entity1 ), and right pontine (one @entity1 , in whom the causality of the @entity64 was uncertain). Of those nine @entity64 presenting with isolated mental symptoms, six (66%) had some focal abnormality on neurological examination. Only three of the 109 @entity1 (2.7%) with no focal findings were ultimately diagnosed as @entity64 , and one of these had a @entity510 . @entity64 was a relatively rare cause of acute @entity911 syndrome. The neurological examination had a very high negative predictive value (97%) and was reliable in selecting @entity1 who should undergo an imaging study.
