“…First, the anatomic locations of ependymomas and hemangioblastomas are different. Ependymomas arise from the central canal of the spinal cord (Kucia et al, 2011) and are located centrally (Kim et al, 2014). Hemangioblastomas are located near the entry zone of the dorsal root, superficially and subpial (Mandigo et al, 2009).…”

“…Second, we did not have enough cases of astrocytoma because our cohort included only adult patients. Third, because of its eccentric location (Kim et al, 2014), astrocytomas were not good candidates for this study.…”

“…Although ependymomas and hemangioblastomas are categorized together in IMSCT, they occur at different anatomic locations and require different surgical techniques. Ependymomas are located centrally (Kim et al, 2014) and can be treated using piecemeal resection and debulking of the tumor with a cavitron ultrasonic aspirator (Brotchi, 2002;Kucia et al, 2011;Takami et al, 2015). In contrast, hemangioblastomas are located posteriorly (Mandigo et al, 2009) and should be removed in an en bloc fashion; debulking of the tumor should be avoided (Brotchi, 2002;Mandigo et al, 2009;Takami et al, 2015).…”

“…The most common intramedullary spinal cord tumors are ependymomas and astrocytic tumors, followed by hemangioblastomas [6,7]. While the morphological MRI of a hemangioblastoma does not usually present a diagnostic challenge, the differentiation between an astrocytoma and an ependymoma often does [8].…”

Role of Diffusion Tensor Imaging Parameters in the Characterization and Differentiation of Infiltrating and Non-Infiltrating Spinal Cord Tumors

Background and Purpose Recent attempts to utilize diffusion tensor imaging (DTI) to identify the extent of microinfiltration of a tumor in the brain have been successful. It was therefore speculated that this technique could also be useful in the spinal cord. The aim of this study was to differentiate between infiltrating and noninfiltrating intramedullary spinal tumors using DTI-derived metrics. Material and Methods The study group consisted of 6 patients with infiltrating and 12 with noninfiltrating spinal cord tumors. Conventional magnetic resonance imaging (MRI) with gadolinium administration was performed followed by DTI. Fractional anisotropy (FA), diffusivity (TRACE) and apparent diffusion coefficient (ADC) were measured in the enhancing tumor mass, peritumoral margins, peritumoral edema and normal appearing spinal cord. The results were compared using non-parametric Mann-Whitney U test with statistical significance p < 0.05. Results In peritumoral margins the FA values were significantly higher in the noninfiltrating compared to the infiltrating tumors (p < 0.007), whereas TRACE values were significantly lower (p < 0.017). The results were similar in peritumoral edema. The FA values in the tumor mass showed no significant differences between the two groups while TRACE showed a statistically significant difference (p < 0.003). There was no statistical difference in any parameters in normal appearing spinal cord. Conclusion Quantitative analysis of DTI parameters of spinal cord tissue surroundings spinal masses can be useful for differentiation between infiltrating and non-infiltrating intramedullary spinal tumors.

“…SEs present with slow, longitudinal growth along the spinal cord and show expandability. Most SEs have clear boundaries, and surgical removal of the whole tumor is the primary treatment option [6][7][8][9][10] . However, absolute tumor boundaries can be difficult to determine, particularly in patients with tumor-associated strokes.…”
