The generally preferred method of imaging in a child suspected of an intracranial or CNS space-occupying lesion.
What is a "contrast MRI of the brain and spine?"
This often must be ordered in conjunction with hematology/oncology and pediatric anesthesiology (for sedation). Urgent CT should be ordered if elevated ICP is a concern.
When to image?
■Persistent headache in the following settings:
•Wakes a child from sleep
•Occurs upon waking
•In any child less than 4 years of age
•Associated with disorientation or confusion
■Persistent vomiting upon waking
■Visual findings including papilledema, optic atrophy, new onset nystagmus, reduced acuity not due to refractive error, visual field reduction, proptosis, and new onset paralytic (non-comitant) squint
■Motor findings including regression in motor skills, focal motor weakness, abnormal gait and/or coordination, bell’s palsy with no improvement over four weeks, and swallowing difficulties without an identifiable local cause
