Tumefactive demyelinating lesions versus CNS neoplasms, a comparative study.

Background: Differentiating tumefactive demyelinating lesions (TDL) from neoplasms of the central nervous system continues to be a diagnostic dilemma in many cases.

Objective: Our study aimed to examine and contrast the clinical and radiological characteristics of TDL, high-grade gliomas (HGG) and primary CNS lymphoma (CNSL).

Method: This was a retrospective review of 66 patients (23 TDL, 31 HGG and 12 CNSL).
