Large intramedullary lesion with fluid-equivalent signal on native T1 and T2 images. Sharp regular borders, no associated edema, no contrast enhancement.
Case Discussion
Given the smooth borders and homogeneous content, the most probable diagnoses would be either developmental ependymal or epidermoid cyst (DWI might have helped here). Histology was not obtained so far.
