A previously healthy 8-month-old girl developed exanthem subitum and acute encephalopathy with status epilepticus, quadriplegia and bilateral abducens nerve palsies. Human herpesvirus-6 DNA was found in the cerebrospinal fluid by the polymerase chain reaction at the acute stage. Cranial computed tomography showed low density areas in the thalami and in the cerebellar and abducens nuclei. The distribution of the lesions was consistent with acute necrotizing encephalopathy. As for the thalamic lesions, a T2 weighted magnetic resonance image on the 24th day of the illness demonstrated low signal intensity surrounded by high intensity; 99mTc-ECD SPECT showed hypoperfusion, which suggested irreversible tissue damage. The patient is now 1 year 6 months old and has spastic quadriparesis with mental retardation and abducens nerve palsies.

We reported two cases of two-year-old girls with hypoxic ischemic encephalopathy. Their symptom was coma induced by seizures with respective factors. CT image on subacute stage showed the decreased density of the whole brain except for the primary sensorimotor cortex and the occipital lobe. MRI and CT images on chronic stage revealed generalized atrophy with no abnormal density areas. 99mTc-ECD SPECT on chronic stage showed low perfusion in the whole brain except for the primary sensorimotor cortex and the occipital lobe, in which areas brain tissue is considered to be injured easily in hypoxic ischemic encephalopathy. The paradoxical distribution of abnormal cerebral perfusion areas in our cases was reported in this paper.

We studied single photon emission computed tomography (SPECT) of 15 children with acute encephalopathy after more than 1 year from the onset, using technetium-99 m-L, L-ethyl cystinate dimer (99mTc-ECD) and a three-dementional stereotaxic region of interest template. Regional cerebral blood flow was evaluated and divided in three groups according to the severity of disability: absent or mild, moderate, and severe. There was no abnormality on SPECT in the patients without disability or with mild disability. Diffuse hypoperfusion was shown in the groups with moderate and severe disability. The patients with severe disability showed hypoperfusion in the pericallosal, frontal and central areas which was more pronounced than in the patients with moderate disability.

We report the case of a 32-year-old man presenting symptoms of parkinsonism. Neurological examination revealed parkinsonism symptoms such as akinesia and postural instability, dementia and frontal lobe signs. He was diagnosed as having human immunodeficiency virus (HIV) encephalopathy. Brain MRI, 99mTc ECD-SPECT and 1H-MR spectroscopy demonstrated symmetrical cerebral white matter lesions, predominantly in the bilateral frontal lobes. Frontal lobe dysfunction could be responsible for his parkinsonism associated with HIV encephalopathy. His neurological symptoms improved transiently after the initiation of HAART but fluctuated when antiretroviral drugs were changed because of their side effects. Although HAART effectively decreased plasma HIV-RNA load and increased peripheral blood CD4 cell count, his parkinsonism and dementia eventually exacerbated. Our results suggest that a combination of antiretroviral drugs affects the therapeutic efficacy against HIV encephalopathy, and that CNS symptoms could be aggravated during HAART, even when plasma HIV-RNA load and CD4 cell count are maintained under favorable conditions.

A 79-year-old female was admitted to our hospital because of unconsciousness and convulsion following mental deterioration. On admission, she exhibited myoclonic movement of the right side of the face and right fingers in addition to rigospasticity and tremors in the right arm and leg. Laboratory tests revealed hyperthyroidism with an increased anti-TSH-R antibody titer. In addition, an echogram indicated excessive blood flow at the thyroid; hence, the patient was diagnosed with Basedow's disease. Interestingly, the tests also revealed increased titer of anti-TPO antibody, anti-Tg antibody, and anti-NH2 terminal of alpha-enolase (NAE) antibody; in addition, an EEG showed abnormal findings potentially indicating periodic synchronous discharge. Brain MRI showed cerebral atrophy, and brain 99mTc-ECD-SPECT images demonstrated an overall decrease in the accumulation of 99mTc in the cerebrum. The abovementioned findings are common to patients with Creutzfeldt-Jakob disease (CJD). We initiated treatment for hyperthyroidism with thiamazole and lugol, but this did not regain consciousness. Because she had anti-thyroid antibody was observed, we considered a differential diagnosis of Hashimoto's encephalopathy and, in fact, methylprednisolone pulse therapy alleviated her symptoms and normalized the EEG findings. The condition in this case clinically mimicked CJD; therefore, the differentiated diagnosis is important because Hashimoto's encephalopathy is treatable disease.
