Resumos
Os autores apresentam o caso de uma paciente com 41 anos de idade que iniciou seu quadro clínico com hemiparesia direita progressiva. A RNM revelou massa expansiva na região temporoparietal esquerda e lesão menor na área frontal direita. O exame do LCR foi normal. Devido à possibilidade de se tratar de tumor ou abscesso, a paciente foi submetida a biópsia cerebral. O resultado revelou tratar-se de área de desmielinização, sendo negativos os testes efetuados para vírus.

A 41 year old woman with subacute onset of moderate and progressive right hemiparesis showed on the MRI a unilateral white matter lesion on the left temporoparietal region and a small lesion on the right frontal region. The CSF was normal. Because possible diagnosis of tumor or abscess, the patient underwent a cerebral biopsy. The histological result was of brain tissue with demyelination and reactive changes. The stains for viral etiology were negative.

SUMMARY
A 41 year old woman with subacute onset of moderate and progressive right hemiparesis showed on the MRI a unilateral white matter lesion on the left temporoparietal region and a small lesion on the right frontal region. The CSF was normal. Because possible diagnosis of tumor or abscess, the patient underwent a cerebral biopsy. The histological result was of brain tissue with demyelination and reactive changes. The stains for viral etiology were negative.
Key-words: multiple sclerosis, MRI, demyelination.
