Neuroradiological Imaging. MRI imaging (a sagittal T1-SE post-contrast; b sagittal T2-TSE: sagittal fat-saturated T1-SE post-contrast; d sagittal T2-TSE, e coronally reconstructed CT; f axially reconstructed CT at the level marked by a line in d; g axial T2-TSE sequence at the level marked by a line in c). (a, c) Strong contrast enhancement of the meningeal structures due to the meningitis are shown in the post-contrast MRI series. The arrowhead in A exemplarily points at the strongly enhancing surface of the spinal cord. The arrow in A points at the contrast-enhancing filum terminale. (b) The level of the medullary cone is at the level of the vertebrates L3 and L4, which is unusually low, see arrow. (c) The distended rectum and a connection to the spinal canal are visible. The meningocele cannot be unequivocally delineated from the rectal carcinoma. (d, e) CT at the level marked by a line in d; (f) axial sequence at the level marked by a line in c) demonstrating a sacral menigocele with tethering of the spinal cord and bony dysraphism
