| Abstract |
Purpose
: This study was performed to be helpful in early diagnosis and treatment of the children with neurologic disorders.
Methods
: One hundred and eighty-five pediatric patients with neurologic disorder were studied from May 1991 to March 1994, ranging in age from neonate to 15 years old. All patients were imaged with MRI. We observed age and sex distribution, frequency and type of positive MRI findings and correlation between MRI findings and age, chief complaints and final diagnosis.
Results
: 1) Eighty(43.2%) of the 185 patients(107 boys, 78 girls) had positive MRI findings. The frequency of abnormality was highest in newborn
2) Abnormalities(80) included white matter lesion(21), atropy(10), benign cystic lesion(8), tumor(8) and miscellaneous(33)
3) Among the 87 patients who had seizures, 33(37.9%) had abnormal MRI results. Eight(22.2%) of 36 patients with headache had abnormal MRI results. The incidene of abnormal MRI results according to chief complaints was high in limb paresis(63.6%), developmental delay (63.2%), visual disturbance(62.5%) and consciousness change(50.0%).
4) MRI was especially useful in diagnosis of tumor, Moyamoya disease, hydrocephalus, congenital anomaly, subdural hematoma and neurocysticercosis, but we did not detect abnormalities on MRI of Guillain-Barre?syndrome and facial nerve palsy.
Conclusion
: We consider MRI to be the sensitive method of evaluating intracranial lesions in neurologic disorders of children. |
