Tumor or Demyelination? Three Tumefactive Multiple Sclerosis Case Reports and Literature Review.

Abstract

To investigate the clinical diagnosis and treatment of tumefactive multiple sclerosis (TMS). Clinical data, laboratory and imaging examinations, and treatment of 3 patients with TMS were retrospectively analyzed. Data were further analyzed in relation to the literature. All 3 patients had acute or subacute onset with large lesions on imaging, which were difficult to differentiate from tumors. Two cases had relapses on follow-up and one case had a stereotactic biopsy. TMS is difficult to differentiate from brain tumors. It is necessary to improve the understanding of these diseases, to apply the correct diagnosis and treatment and to avoid unnecessary invasive surgery and inappropriate treatment.
