We present 19 @entity1 with @entity2916 and @entity816 . The mean age at the time of @entity5 diagnosis was 9.4 years (range, 1.5 to 21 years). Computed cranial tomography (CT) or cranial magnetic resonance imaging (MRI) identified the lesion which was resected in all cases. Seven @entity1 had @entity1276 and there was an interval increase in the @entity5 size or a large @entity5 without @entity1276 in 12 @entity1 . Surgical criteria included: (1) presence of @entity1276 ; (2) interval increase in @entity5 size; (3) new focal @entity51 attributable to the @entity5 ; and/or (4) symptoms of @entity428 . Eight @entity1 were identified through a surveillance program involving annual computed cranial tomography. All of these eight @entity1 had their @entity5 removed prior to the development of symptoms, none had @entity51 which persisted after surgery, and none has so far developed recurrent @entity816 . In contrast, of the 11 @entity1 from the non-surveillance group 7 were symptomatic at @entity5 diagnosis, 1 had a complicated postoperative course, 2 developed recurrent @entity816 , and 1 had an extensive lesion that could not be completely excised. Periodic cranial imaging may help to identify @entity816 in @entity2916 @entity1 before they become symptomatic. Earlier diagnosis and treatment could reduce surgical morbidity and the risk of @entity5 recurrence.

Early diagnosis of @entity816 in XXXX with @entity2916 .
