CANESSA G, José A et al. Fluorodeoxiglucose F¹⁸ positron emission tomography imaging (F¹⁸ FDG) for the assessment of rising levels of serum CA 19-9 in pancreatic mucinous cystadenocarcinoma. Report of one case. Rev. méd. Chile [online]. 2004, vol.132, n.3, pp.347-352. ISSN 0034-9887.  http://dx.doi.org/10.4067/S0034-98872004000300010.

We report a 38 years old female patient with a pancreatic mucinous cystadenocarcinoma. She presented at the onset with a peritoneal rupture that required emergency surgery. Five months later, the patient was subjected to a segmental pancreatectomy and splenectomy. One year later, the patient had a serious gastric bleeding secondary to a gastric ulcer. Due to a persistent increase in her CA 19-9 levels, a Positron Emission Tomography (PET) functional imaging with fluorine 18-deoxyglucose (F¹⁸FDG) was done. It showed an intense focal hypermetabolism in the gastric wall reported as a secondary tumour location. The patient was subjected to a total gastrectomy and Roux en Y anastomosis, with a good outcome. The pathological study confirmed the presence of a metastasis of an adenocarcinoma in the gastric wall. The relative value of CA 19-9 markers and FDG PET in pancreatic and gastric carcinomas is discussed (Rev Méd Chile 2004; 132: 347-52).
