We herein report a case of laparoscopic adrenalectomy for solitary adrenal metastasis from intrahepatic cholangiocarcinoma (ICC). Although the treatment of extrahepatic metastasis from primary liver tumors is essentially palliative, solitary metastasis from such tumors offers the possibility of a cure by surgical resection. The adrenal gland is an uncommon site for metastasis from ICC. A patient who had received a right hepatic lobectomy with lymph node resection for ICC later developed a heterochronous adrenal metastasis, and thus underwent laparoscopic adrenalectomy 30 months after the liver resection. To the best of our knowledge, this is the first case of adrenalectomy for heterochronous metastasis from ICC., Acta medica Nagasakiensia, 58(4), pp.131-134; 2014

Incidentally discovered adrenal masses are a common diagnostic problem. While computed tomography (CT) and magnetic resonance (MR) imaging can adequately characterize most benign or malignant adrenal masses, in some cases the results are indeterminate. We report and discuss a case of an adrenal metastasis with misleading clinical and CT features, in which an abnormal metabolic uptake detected through fluorine 18-fluoro-deoxy-glucose positron emission tomography ((18)F-FDG PET)-CT raised the suspicion of adrenal metastasis relatively early compared with apparently normal results on repeated follow-up CT examinations.

FDG uptake in the metabolically active brown adipose tissue (BAT) is a source of significant concern while interpreting FDG-PET studies. It is also of great interest due to its potential implications for obesity research. In this communication, we describe hitherto unreported asymmetric BAT uptake in the abdomen, persisting after diazepam intervention in the repeat PET study on a separate day. The patient did not have any evidence of disease even at 24 months' follow up. The present case is a useful addition to the current body of literature of false positive FDG-PET due to BAT uptake in unusual location and underscores the importance of high index of suspicion and careful correlation, whenever one comes across an unusual PET finding in a given clinical situation. This assumes important diagnostic value particularly when it coexists in the setting of malignancy where the disease can be falsely upstaged by misinterpretation. The literature relevant to the report is discussed and a schema is suggested for correct interpretation.

Despite progress in therapy for hepatocellular carcinoma, management of extrahepatic metastatic lesions remains problematic. A 73-year-old man who underwent transcatheter arterial embolization for hepatocellular carcinoma presented bilateral adrenal metastases. Ten months after transcatheter arterial embolization, computed tomography detected huge tumors in both adrenal glands....
