Review Case Reports
Persistent Working Memory Impairment Associated with Cerebral Infarction in the Anterior Cingulate Cortex: A Case Report and a Literature Review.
A 52-year-old man experienced sudden-onset global amnesia and left limb ataxia. An embolism of the right anterior cerebral artery resulted in anterior cingulate cortex (ACC) infarction, and working memory dysfunction persisted. ⋯ The areas showing a decreased activity on SPECT were responsible for the working memory, which corresponded to the observed symptoms. This is the first case in which limited ACC infarction resulted in permanent working memory dysfunction, and SPECT revealed the decreasing working memory in the associated region.

Primary Extragastrointestinal Stromal Tumor of Greater Omentum with Intraperitoneal Bleeding: A Case Report.
Gastrointestinal stromal tumors (GISTs) develop in the digestive tract, mainly in the stomach, small intestine, colon, or esophagus. However, primary tumors with the same pathologic features as GISTs have been reported to occur outside of the digestive tract and are called extragastrointestinal stromal tumor (EGIST). We herein report a rare case of EGIST arising from the greater omentum in a patient with abdominal pain caused by intraperitoneal bleeding from the tumor.

Case Reports
Cartilage-hair Hypoplasia Complicated with Liver Cirrhosis Due to Chronic Intrahepatic Cholestasis: A Case Report.
We herein report a rare case of cartilage-hair hypoplasia (CHH) complicated with liver cirrhosis. A 20-year-old Japanese man with CHH was found incidentally to have liver cirrhosis and an esophageal varix. This patient had been treated for infections due to immunodeficiency since early childhood. ⋯ An autopsy revealed an abnormality of the interlobular bile ducts and intrahepatic cholestasis. Liver cirrhosis was thought to have been caused by chronic intrahepatic cholestasis due to biliary duct hypoplasia and changes in the intestinal microbiome. Therefore, CHH may cause biliary cirrhosis due to multiple effects.
