      Non-neoplastic demyelinating processes of the brain with ring enhancing lesions and mass effect on MRI imaging, mimicking malignant brain tumours, are rare phenomena.
      We document the case of a 32 year old male with clinical, radiological and initial histological findings, suggestive of a malignant brain tumour. Additional investigations confirmed the diagnosis of multiple sclerosis.
      This case is significant as the lesion could not be easily distinguished from a malignant brain tumour on imaging alone. Cases such as this illustrate the importance of considering a demyelinating process in the differential diagnosis of tumour-like brain lesions.
