  • Title: Spinal neurilemmomas and neurofibromas: central dot sign in postgadolinium MRI.
    Author: Gouliamos AD, Kontogiannis DS, Androulidakis J, Kalovidouris AE, Vlahos LJ, Papavasiliou CG.
    Journal: J Comput Assist Tomogr; 1993; 17(3):446-8. PubMed ID: 8491909.
    Abstract:
    The MR studies of three histologically proven spinal neurilemmomas and neurofibromas were reviewed retrospectively. There were two benign neurilemmomas (schwannomas) and one neurofibroma. The common characteristic of these cases was a central low intensity focus ("dot") seen on postcontrast T1-weighted imaging. The low intensity foci corresponded histologically to a congeries of changes including edema, microcysts, foam cells, hyalinization of blood vessels, old hemorrhage, and dystrophic calcification.
