RESUMEN

The paper presents the analysis of the results of the examination of 90 patients with syringomyelia using magnetic-resonance "Bruker" tomograph with the intensity of the magnetic field 0.23 T. The observation was carried out according to the authors' classification. Symptom complex of syringomyelia corresponding to the anatomic disorders of the spinal cord was described. The authors made a conclusion, that the magnetic-resonance tomography, as the most informative method, was a method of choice in syringomyelia. In 21% of the patients there was idiopathic syringomyelia; in 47.3% a process spread to the caudal regions of medulla oblongata. In 79% cases syringomyelia manifested as a syndrome; in 50% of the total cases it was found in Arnold--Chiari anomaly.

RESUMEN

Magnetic-resonance tomography (MRT) helped obtain a high-resolution image characterized by high sensitivity in respect of soft tissue contrast visualization and providing direct imaging of the spinal cord and its radicles. This method is useful in the diagnosis of injuries to the spine and cord. A total of 64 patients of both sexes aged 6 to 67 were examined. The primary diagnosis of traumatic changes in the spine and cord was confirmed by MRT in only 62% of cases. Two groups of patients were singled out: with acute and chronic injuries, subdivided into subgroups with and without spinal cord dysfunction. The detected changes were divided into extramedullary (traumatic disk hernias, compression of the cord or radicles with a dislocated bone fragment, epidural hematoma) and intramedullary (edema, hemorrhages, spinal cord disruption); MRT diagnosis of intramedullary changes is particularly important, more so in the absence of bone injuries. In remote periods after the trauma the clinical picture was determined by spinal canal stenosis, cicatricial atrophic and adhesive changes eventually blocking the liquor space. Intramedullary changes presented as spinal cord cysts or syringomyelia. A classification of the detected changes by the types of injuries and their aftereffects is presented in the paper. The authors emphasize the desirability of MRT in spinal injuries with signs of cord dysfunction.

RESUMEN

Though syringobulbia is a rare condition, the problem of its differentiation from other craniospinal abnormalities is a pressing one. This problem may be considered solved due to introduction of nuclear magnetic tomography (NMT). Studies carried out in 43 patients helped distinguish the NMT symptoms most characteristic of syringobulbia: a centrally located echo signal zone in the medulla oblongata and the cord, the echo signal in this zone being equivalent to that of the cerebrospinal fluid or gliosis, increased transverse size of the medulla oblongata and the spinal cord, dilated volumes of the basal cysterns. A craniospinal condition resultant from a tumor process is characterized by detection of a bulky formation with a heterologous structure in the medulla oblongata, involving the cervical portion of the cord and the cerebellar structures. It is associated with a perifocal edema and IVth ventricle deformation; this latter condition is often undetectable, and occlusive hydrocephalus develops. Since NMT often permits a differential diagnosis between syringobulbia and craniospinal tumors, it must become the method of choice in patients with these conditions.

RESUMEN

Magnetic resonance tomographic findings and clinical symptoms were compared by using the results of 596 studies. The clinical diagnoses and types of Arnold-Chiari's anomaly, which were revealed by magnetic resonance tomography as groups I, II, and III were also evaluated. A contribution of fluid dynamic disorders, including intracranial hypertension and hydrocephalus, was assessed. No relationship was found between the clinical manifestations and the ascending degree of cerebellar tonsils. The combination of Arnold-Chiari's anomaly with syringomyelia and osteochondrosis and a role of magnetic resonance tomography in the identification of the anomaly for correct choice of therapy in spinal pathology were shown. It was concluded that magnetic resonance tomography should be used in all cases of spinal diseases or suspected diseases of the craniospinal transition.
