The Pancreatic Hypermetabolic Lesions of Lung Carcinoma Patients in F-18-Fluorodeoxyglucose PET-CT: Correlation with Pathology

Abstract

Aim: The ratio and results of the hypermetabolic lesions of the pancreas in lung carcinoma patients in FDG PET-CT which is rare, wasn’t sufficiently evaluated previously in the literature. The aim of this study was to determine these lesions’ pathologic correlations. Materials and Methods: The F-18 FDG PET/CT images of the 516 patients with Lung Carcinoma was evaluated retrospectively by an Experienced Nuclear Medicine Physician and correlation of Pathology results were analyzed. Results: The ratio of the pancreatic hypermetabolic lesions were 7% (36 patients). Pathology results revealed small cell lung carcinoma metastasis in 23, adenocarcinoma in 8, squamous cell carcinoma in 1 and atypical carcinoid tumor in 1 and other pathology types in rest of the patients in primary Lung Carcinoma. Five of the pancreatic lesions pathology results could be obtained and three were small cell lung carcinoma, one of them was adenocarcinoma and the squamous cell carcinoma in other one. Conclusion: The hypermetabolic pancreatic lesions in Lung Carcinoma patients in F-18 FDG PET/CT should be evaluated and considered carefully. Since unexpected pathology results could be achieved.
