Coexistence of Multiple Sclerosis and Brain Tumor: An Uncommon Diagnostic Challenge

open access: yesAdvanced Biomedical Research, 2017
Nonneoplastic demyelinating processes of the brain with mass effect on magnetic resonance imaging can cause diagnostic difficulties. It requires differential diagnosis between the tumefactive demyelinating lesion and the coexistence of neoplasm.

Advanced Imaging Applications in Tumefactive Demyelination – Literature Review With an Illustrative Case Report

open access: yesClinical Neuroimaging, Volume 3, Issue 1, 2026.
ABSTRACT Background and Purpose Solitary tumefactive demyelinating lesions (TDLs) represent an uncommon but clinically significant manifestation of central nervous system demyelination and pose a major diagnostic challenge due to their radiologic resemblance to high‐grade gliomas, primary central nervous system lymphoma, and other mass‐like lesions ...

The Associations Between Chronic Active Lesions and White Matter Disease: A 7 Tesla Imaging Study

open access: yesAnnals of Clinical and Translational Neurology, Volume 12, Issue 12, Page 2535-2545, December 2025.
ABSTRACT Background The relationship between paramagnetic rim lesions (PRLs) and surrounding normally appearing white matter (NAWM) disease, potentially contributory to the associations seen between PRLs and clinical impairment, is underexplored. Objectives To assess whether PRLs correlate with a greater degree of NAWM injury in early MS.
