  ABSTRACT: Spinal cord injuries often occur in cases of multiple trauma, can occur alone or in combination with concomitant injuries and are mostly associated with high morbidity and mortality. They often result in lifelong impairment and need for medical care. Radiologic diagnostics are crucial in the acute setting as well as in the long-term treatment of spinal cord injuries. Besides an overview of diagnostic and therapeutic management, typical magnetic resonance imaging (MRI) findings in the acute and chronic stages of spinal cord injuries are presented in this article. Post-traumatic syringomyelia can even develop years after the initial injury of the spine or spinal cord. As syringomyelia can also occur in association with tumors, developmental anomalies and also idiopathically, a thorough MRI diagnostic is essential especially in any case of newly diagnosed syringomyelia.

  ABSTRACT: Intradural tumors are classified into extramedullary and intramedullary localization. A distinct attribution to one of these compartments is essential for finding the appropriate diagnosis. In the radiological evaluation of intradural tumors magnetic resonance imaging (MRI) is the most important method and in contrast to osseous spinal tumors, radiography and computed tomography are of minor importance. According to the globally established WHO grading system, tumors of the central nervous system are histopathologically classified into four grades. Through grades I to IV malignancy and proliferative activity increase. Prognosis is inversely correlated to the WHO grade. Intradural tumors are generally treated by neurosurgeons. Besides neurological symptoms intradural tumors often cause spinal malpositioning. Thus knowledge of the most frequent intradural tumors and their characteristic magnetic resonance findings are important in the orthopedic practice.

  ABSTRACT: Radiological investigation of spinal tumors includes identification of the suspect lesions as well as their relation to surrounding critical structures, such as nerve roots and the myelon. With the use of computed tomography (CT) the delineation of bone and with magnetic resonance tomography the assessment of bone marrow and soft tissue are possible with high-spatial resolution and multi-planar reconstructions. The consolidation of clinical information, distribution pattern and morphology of the lesion itself results in the final radiological evaluation. Because of low invasiveness and complications, CT-guided biopsy is a common tool in cases of suspected lesions. With the help of multi-planar reconstructions even difficult approaches are possible without impairment of critical structures. This review article discusses typical imaging characteristics of common tumors originating from the vertebral column after a section on basic and general aspects of tumor diagnostics.
