Diffusion-Weighted Magnetic Resonance Imaging of an Intramedullary Epidermoid Cyst with Dorsal Dermal Sinus Tract in a Toddler
Figure 1
Axial T2-W (a), sagittal T2-W (b), and DW (c) MR images. (a) A hyperintense well-defined, round, intramedullary lesion is seen spanning T3–T6 vertebral levels. (b) The hyperintense lesion demonstrates continuity with the skin surface consistent with a dorsal sinus tract. (c) There is hyperintensity of the spinal lesion on the sagittal DW image consistent with restricted water diffusion.
