Acute encephalopathy is classified into multiple syndromes, such as acute encephalopathy with biphasic seizures and late reduced diffusion (AESD), clinically mild encephalitis/encephalopathy with a reversible splenial lesion (MERS) and acute necrotizing encephalopathy (ANE), characterized radiologically by lesions in the cerebral subcortical white matter, splenium of the corpus callosum and bilateral thalami, respectively. We described a previously healthy 8-year-old boy who had febrile and biphasic seizures, and encephalopathy. MRI showed abnormal signal intensity in the corpus callosum on day 2 and cerebral subcortical white matter and bilateral thalamic lesions on day 8. This is the first case of acute encephalopathy in which callosal, subcortical and thalamic lesions co-existed. The clinical course of this case was typical for AESD, atypical for MERS, and different from that of ANE.

We report three cases of mucin-producing carcinoma of the gallbladder, along with the magnetic resonance (MR) findings, especially the findings on a MR cholangiopancreatography. In our cases, linear or curvilinear streaks were detected running along the long axis of an enlarged gallbladder (mucus thread sign). When such findings were seen, a mucin-producing carcinoma of the gallbladder should be included as a differential diagnosis. Thus, gadolinium-enhanced MR imaging is mandatory for the precise diagnosis of the mucin-producing carcinoma of the gallbladder.
