A 43-year-old male presented with right side clumsiness for 7 days. Brain magnetic resonance imaging
showed a large ring lesion with gadolinium enhancement in the left parietal lobe, suspicious for
brain tumor. We recognized through brain biopsy that it would not be a brain tumor but a tumefactive
demyelinating lesion. Our report of the clinical, radiological and pathological features of a tumefactive
demyelinating lesion reemphasize that such a demyelinating process should also be considered
in the differential diagnosis of tumor-like brain lesions.
