A 64-year-old @entity1 developed progressive @entity303 and @entity1662 with @entity2045 over 2 months. Neurological examination revealed mild @entity1282 and negative @entity2045 of both hands. Electroencephalography (EEG) showed continuous periodic synchronous discharge (PSD) of 1 Hz, although his EEG abnormality was not similar to that usually observed in @entity3605 ( @entity3605 ). Magnetic resonance imaging (MRI) of the brain revealed only few lacunes. Laboratory data were also normal. Since his consciousness level fluctuated and the PSD were spiky, we came to a diagnosis of @entity159 ( @entity159 ). After administering the @entity1092 , his symptoms and EEG finding improved. Nine months after the onset, despite his continued @entity1092 , the @entity1 had recurrent @entity159 and PSD of 1 Hz. Diffusion-weighted MRI showed a T2-hyperintense lesion in the right parietal lobe, where SPECT scans showed hyperperfusion. After adding @entity10315 , he improved slowly. The follow-up MRI and SPECT showed a disappearance of the previous lesion. Now CT scans of the abdomen showed enlarged periaortic lymph node and endoscopic ultrasonography disclosed a @entity5 of the @entity1819 . Biopsy of the periaortic lymph node by laparotomy revealed undifferentiated @entity420 with its origin being unclear. Chemotherapy didn't work well for the @entity5 and the @entity1 underwent a downhill course, although his mental and neurological manifestation were mostly unremarkable. Two years and four months after the onset, he died in emaciation. Autopsy confirmed @entity4153 originating in the @entity1819 and @entity3 in the liver and lungs. Neuropathological examination revealed only mild scattered @entity5219 . This case was unique in the prolonged @entity3605 -like manifestations, which turned out to be due to @entity159 . Despite anti-neuronal antibodies were not detected, we suspect yet another paraneoplastic @entity75 in this @entity1 .

[An autopsy case of XXXX associated with small cell carcinoma of the stomach with @entity159 resembling @entity3605 ].
