The radiological evaluation of the child with a myelomeningocele.
Seven hundred fifty-five children with myelomeningoceles were evaluated radiologically at the Children's Memorial Hospital in Chicago. From our material, we propose a diagnostic radiologic model to accurately evaluate the neurological problems in the myelomeningocele child. This model is based on the clinical symptoms in these children and the radiologic modalities of magnetic resonance imaging (MRI), computed tomography (CT), ultrasound, myelography, and plain radiographs. We found MRI to be the best modality to evaluate the posterior fossa and total spine. Computed tomography and ultrasound are used to evaluate ventricular size. At times MRI may not adequately diagnose subtle cases of tethering of the spinal cord, cord infarction, arachnoid cysts, or diastematomyelia. In these cases, further evaluation may be necessary with real time ultrasound to look at cord pulsations and water soluble myelography with follow through CT to differentiate cord infarction, arachnoid cyst, localized hydromyelia, or diastematomyelia. If MRI is not adequate to completely visualize the cord because of the severe nature of the scoliosis, then water soluble myelography with CT is indicated.
