A 630-g male infant developed presumed necrotizing enterocolitis (NEC) after fungal enteritis that resulted in subsequent fungal septicemia associated with pneumoperitoneum on the 9th day of life. Urgent percutaneous Penrose drainage was required. During the operation on the 14th day, an ileoileal intussusception and an ileal stricture were found with perforations on each oral side of the lesions. The distinction between NEC and intussusception in premature infants when they coexist can be difficult, as these conditions share common symptoms. The relation between ischemic injury and dysmotility of the intestine is also discussed. The similarity of intrauterine fetal distress and NEC in premature infants, as seen in the present case of the intussusception associated with focal NEC, suggests that mesenteric and enteric vascular ischemia could be one trigger of intussusception in neonates.

Although several reports have revealed that fluorine-18 fluorodeoxyglucose positron emission tomography ((18)F-FDG PET) is useful for differentiating between benign and malignant lesions in the gallbladder, the positive results of (18)F-FDG PET are not specific for malignancy because (18)F-FDG is also accumulated in inflammatory lesions. It is known that the most important pathway for (18)F-FDG to enter the cell body is mediated by the facilitative glucose transporter-1 (GLUT-1) through GLUT-3. We herein present a case of xanthogranulomatous cholecystitis (XGC) with a positive result on (18)F-FDG PET. In this case, GLUT-1 and GLUT-3 were both positively expressed in inflammatory cells at the gallbladder wall of XGC and this is the first report to reveal GLUT expression in XGC. This report reveals that surgeons should carefully consider the appropriate treatment of gallbladder tumor, even with a positive result on (18)F-FDG PET.
