“…Animal studies notably showed that axial and radial diffusivities are good predictors of axonal loss and demyelination, respectively (Budde et al, 2007). DTI has been applied to assess the severity of the spinal cord injury (Agosta et al, 2007;Budde et al, 2007;Cohen-Adad et al, 2008a;DeBoy et al, 2007;Deo et al, 2006;Ducreux et al, 2007;Ellingson et al, 2008;Fujiyoshi et al, 2007;Kim et al, 2007;Lammertse et al, 2007;Nevo et al, 2001;Ohgiya et al, 2007;Plank et al, 2007;Ries et al, 2000;Schwartz et al, 2005;Shen et al, 2007;Thurnher and Bammer, 2006;Valsasina et al, 2005;Vargas et al, 2007). As an extension to DTI, high angular resolution diffusion imaging (HARDI) and Q-Ball imaging (QBI) can represent more than one diffusion direction, thereby alleviating limitations of the diffusion tensor in presence of crossing fibers (Tuch, 2004).…”

“…The peak incidence of spinal meningiomas is in the fifth and sixth decades with there being an almost ten to one predilection for females. In the spine, meningiomas are thought to arise from the denticulate ligaments and more than 95% are classified as WHO Grade I [3]. Their extradural component is most commonly related to extension from an intradural mass.…”

“…Consideration for lymphoma led to a repeat MRI with diffusion restriction, as prior studies have shown the utility of diffusion-weighted imaging (DWI) in the assessment of spinal lymphoma and other highly cellular tumors [2-3]. The tumor demonstrated marked restriction, supporting a possibility of lymphoma (Figure 2).…”

Spinal meningiomas are the most common of adult spinal tumors. Spinal meningiomas account for up to 45% of all intradural spinal tumors in adults and up to 25% of all spinal tumors. While spinal meningiomas are traditionally classified as intradural lesions, up to 14% may have an extradural component. Preoperative evaluation and directed use of imaging techniques are key in these rare but observed cases, to accurately diagnose and direct therapy. In this report, the authors present a case of a 61-year-old female with an incidentally found, exclusively extradural thoracic meningioma treated with surgical resection, highlighting key radiographic pearls in the evaluation of these uncommon lesions.

“…To allow accurate evaluation of tumour extension in cervical spine, it is of great importance to perform proper imaging. Currently, magnetic resonance imaging (MRI) provides excellent information to assess tumour extension in soft tissue [13,14]. Moreover, it provides images which allow surgeon to differentiate whether intra-spinal or nerve root compression is caused by tumour itself or edema.…”

The spinal column is the most common site of skeletal secondary tumours. Metastatic tumours spreading to spine cause growing problem to the aging population. Patients suffer from immobilizing pain, instability of the spine and secondary neurologic deficits. In most patients treatment is palliative. By improving therapy of tumour-induced instability of the spine and tumour-induced pain, patients' quality of life can be significantly improved and medical costs significantly lowered. In the past, the traditional therapy of metastatic spinal tumours was based on fractionated external beam radiotherapy. Surgical approach was limited to laminectomy (decompression). Nowadays, surgery focuses on preservation and restoration of neurologic function and stability of the spine by marginal resection, and immediate posterior and anterior stabilization. In addition, development of new surgical techniques such as radiofrequency thermoablation and kyphoplasty allowed surgeons address some of the problems related to lytic destruction of the vertebra without increasing morbidity and mortality of the patients associated with open surgery. However, proper treatment of the cervical spine metastases can be achieved only by multidisciplinary team work.
