Evaluation Medical history Physical examination Neurological examination > 98% of children with brain tumors have objective neurologic findings
Diagnostic testing Routine laboratory CSF examination EEG Neuroimaging: CT, MR
EEG1,148 children with recurrent headache(slowing, spike&sharp, other)
EEG - Conclusions EEG is not recommended EEG: Normal or nonspecific abnormalities No differences between migraine/nonmig

NeuroimagingConclusions Surgical treatment - 2.3% All had neurol. abnormalities on exam. No patient with a normal neurol. Exam. had a lesion that required surgical treatment
Neuroimaging Recommendations Not indicated on a routine basis Considered: 1. abnormal neurological exam 2. history of - recent onset change in type associated features that suggest neurologic dysfunction
Clues to organic brain lesion 1. Severe headache of recent onset 2. Chronic & progressive 3. Localized pain 4. Wakes child at night 5. Early morning & increase in severity 6. Associated neurological symptoms & signs
