title: Transcranial eosinophilic granuloma manifested by a subcutaneous scalp mass. Differential diagnosis in children.
abstract: BACKGROUND
  The differential diagnosis of nodular scalp lesions in a child is surprisingly extensive.
  
  
  OBJECTIVE
  To present a case of eosinophilic granuloma that was manifested by a scalp mass in a pediatric patient.
  
  
  METHODS
  The case is presented and the relevant literature is reviewed.
  
  
  CONCLUSIONS
  The seriousness of some of these lesions requires a thorough evaluation, including noninvasive imaging, and carefully planned surgical intervention so that effective diagnosis and treatment are ensured. Surgical exposure of unsuspected central nervous system connections may lead to infection, hemorrhage, seizures, or other significant morbidity and mortality.
