[Unusually located metastatic tumors of the spine--three case reports].

Metastatic spine tumors are representing a growing number of oncological patients. In this paper the authors would like to focus on a rare type of metastatic spine tumors, the unusually located ones. Since the advent of MRI and with the progress in general oncology this formerly rare tumors became more frequently recognized. Consequently these tumors are causing a new challenge for the oncologists, neurologists and neurosurgeons as well. The aim of the authors with this paper was to raise, especially the neurologists' attention to this emerging problem.
