title: [Diagnosis of acute disseminated encephalomyelitis using a stereotaxic biopsy: Report of one case].
abstract: We report a 15 year-old female presenting with behavioral disturbances, headache, left hemiparesis and paresis of the vertical gaze. CAT scan and magnetic resonance showed an involvement of right thalamus, third ventricle and medial temporal lobe suggesting an encephalitis or lymphoma. 201Thalium SPECT suggested a lymphoma. A stereotaxic biopsy showed a subacute demyelinizing lesion, compatible with an acute disseminated encephalomyelitis. The patient was treated with Methylprednisolone with resolution of symptoms. She remains in good condition after one year of follow-up.
