Purpose

- Review a compartmental approach to the diagnosis of spinal tumors - Review the epidemiologic considerations, characteristic imaging appearances, & histopathologic findings of intramedullary & intradural/extramedullary spinal tumors - Illustrate the utility of diffusion tensor imaging & fiber tractography in pretreatment evaluation of intramedullary tumors

Methods & Materials

Cases of primary intramedullary and intradural/extramedullary spine tumors are presented with corresponding pathologic & surgical specimens, where available. Examples of fiber tractography in intramedullary tumors are shown with discussion of relevant analogous histopathologic features.

Conclusion

A compartmental approach to the diagnosis of spinal lesions is important for formulating a reasonable differential diagnosis, taking into account clinical presentation and patient age. Diffusion tensor imaging can be a useful tool for preoperative evaluation of intramedullary tumors, and can mirror histopathologic findings. Familiarity with histo-pathologic features will likely become increasingly useful as the use of advanced imaging techniques in the spine increases.
