From 1986 to 1993, 12 cases of @entity693 were identified at the Veterans General Hospital, Taipei. Most of the cases were caused by @entity797 and three cases were mixed @entity4008 . There were six adult and six pediatric @entity1 . Among the adult @entity1 , four had undergone neurosurgical procedures before onset of @entity693 and the other two had severe chronic underlying diseases. In contrast, all six pediatric @entity1 had underlying central nervous system (CNS) pathology such as meningomyelocele or @entity1276 . Placement of CNS devices was the most important predisposing factor of @entity693 in this study series.
