Long-term follow-up of children with magnetic resonance imaging and ultrasound after treatment of brain tumors
This paper compares the results of MRI and US follow-up examinations of 46 children who had undergone surgery for brain tumors. The cases included 42 posterior fossa tumors, 3 supratentorial tumors and 1 upper cervical spinal cord tumor. US examination proved to be less specific and sensitive than MRI. However, when a "bone window" is available, US is, because of the ease of its application, better suited for frequent routine examinations. Long-term follow-up should, therefore, consist of frequent regular US examinations combined with yearly MRI examinations.
Magnetic resonance imaging in infections of the brain: findings in tuberculosis, listeriosis, toxoplasmosis, subacute sclerosing panencephalitis, and multiple sclerosis.
A total of 6 patients with various inflammatory brain diseases were investigated by MRI. Typical diagnostic criteria like signal intensity, location, and morphology of the lesions are presented. MRI proves to be a highly sensitive method to detect encephalitic foci, which, however, suffers from a low specificity. Therefore additional informations like case history, clinical findings, and serological data have to be considered to find the correct diagnosis.
Magnetic resonance imaging of postrepair-myelomeningocele — findings in 31 children and adolescents
Magnetic resonance imaging has clearly demonstrated its efficacy in the diagnosis of pathological processes in the C.N.S. We examined 31 children who had undergone plastic closure of myelomeningocele a few days post partum. We could show that a high percentage of the patients (89%) presented the pathological anatomy of a tethered spinal cord; clinical symptoms of the tethered spinal cord syndrome, i.e. progressive neurological symptoms, however, are rarely observed. Possible revision of neurosurgical treatment of MMC is discussed.
