A 68-year-old man was hospitalized on 24 June, 1998 because of visual and gait disturbance. A month before admission, he had been aware of blurred or double vision while watching TV. A few days later, he developed dysphagia and clumsiness in the fingers. His gait became unstable and he exhibited restless finger movements. His shoulders and trunk showed torsion while walking. On admission, he became disoriented and showed rigidity in the legs and athetosis in the bilateral fingers. Routine laboratory findings, thyroid function data, and the serum levels of vitamin B1, B12, Cu, and ceruloplasmin were within the normal ranges. Periodic synchronous discharges (PSD) were observed on electroencephalography. MRI showed T2-high intensity and atrophy of the bilateral caudate nucleus and putamen in addition to the cerebral cortex. 99mTc-ECD-SPECT showed a decrease of local blood flow in the bilateral frontal, right temporal, and bilateral parietal lobes and bilateral thalami. Athetosis became exacerbated and was observed for a month, overlapping with myoclonus. We diagnosed the patient as having CJD because of progressive dementia, myoclonus and PSD. Analysis of the prion protein revealed that codon 129 was Met/Met and codon 219 Glu/Glu by DNA sequences. The patient developed akinetic mutism and rigid contracture, and died of pneumonia on 5 September, 1998. Because athetosis is thought to involve the bilateral caudate nucleus, putamen and thalamus, the findings of diagnostic imaging in this patient might be relative to the clinical symptoms.

Creutzfeldt-Jakob disease (CJD) is a presenile dementia characterized by rapidly progressive mental deterioration, myoclonic jerking, and other less common neurological signs. Few autoctonous cases have been described in Brazil. A 54-year-old white woman, was admitted in our service with a month history of progressive, bilateral cortical blindness. After admission, she developed right partial motor seizures( right facial, upper and lower limbs), she became progressively aphasic( mixed aphasia). Seizures were controlled with phenytoin, but she developed choreoathetotic movements on her right dimidium, with partial control after introduction of chlorpromazine 25 mg q/d. She could no longer stand up or walk due to severe ataxia. The first EEG (October, 2001) showed left hemisphere severe seizure activity (status epilepticus partialis). She was delivered home with enteral nutrition, phenytoin, chlorpromazine and mepacrine 100 mg qd. The following laboratorial tests were negative or normal: blood series, platelets, ESR, kidney and liver function, copper, ceruloplasmin, VDRL, HIV, HTLV-1, lactate, and cerebral DSA (performed in other service).A spinal tap with normal opening pressure was perform and CSF examination was normal. CSF 14-3-3 protein was positive, CSF specific neuronal enolase 7.5 ng/ml(normal). Genetic study of PRNP gene did not disclosed any known mutation. A MRI (October, 2001) showed areas of hyperintense signal (T2 and FLAIR) without Gd-enhancement on T1, in the left temporal lobe and in both occipital lobes; basal ganglia have a normal appearance. DWI imaging showed bright areas at the same sites. An EEG (March, 2002) disclosed a periodical sharp triphasic waves pattern, suggestive of CJD. A second MRI (April, 2002) showed mild generalized atrophy, no ventricular dilatation, and the hyperintense sites disappeared. She remained clinically stable and under use of chlorpromazine and mepacrine until she died due to pulmonary complications on April, 2003.

Creutzfeldt-Jakob disease (CJD) is a fatal neurodegenerative disorder typically characterized by progressive dementia associated with myoclonus, cerebellar and other focal neurological signs. Electroencephalogram, brain MRI and cerebrospinal fluid (CSF) analyses are helpful diagnostic tools, but diagnosis in patients with atypical presenting neurological signs is often difficult to make. A 55-year-old woman developed disorientation, drowsiness and focal motor signs after a traumatic brain injury due to an accidental fall. In two weeks, her symptoms worsened in spite of a brain MRI showed an improvement of traumatic lesions, but the presence of bilateral hyperintensity in the basal nuclei was suggestive of a metabolic or prion encephalopathy. The high 24-h urinary copper level and reduction of ceruloplasmin initially supported the diagnosis of Wilson's disease, but the absence of Kayser-Fleischer rings, and the positivity of 14-3-3 protein test and elevated tau concentrations in the CSF oriented toward a diagnosis of CJD. She died 5 months after the onset, and the postmortem examination of the brain revealed immunochemical features of CJD. This case exemplifies the difficulty of a timely diagnosis when rapid progressive dementia is masked by concomitant factors (i.e., head trauma) and neurological signs are associated with unclear laboratory findings.
