18F-FDG PET/CT in the Detection of Undifferentiated Carcinoma With Osteoclast-like Giant Cells of the Pancreas

Abstract: Undifferentiated carcinoma with osteoclast-like giant cells of the pancreas (UCOGCP) is a rare nonendocrine pancreatic tumor. We present a case of a very small UCOGCP. 18F-FDG PET/CT revealed a solid mass measuring 1.0 × 0.8 cm on CT images with an SUVmax of 5.0 in the body of the pancreas. CT revealed a solid mass with significant enhancement. The histopathologic and immunohistochemical studies confirmed the diagnosis. Our findings indicate 18F-FDG PET/CT is a useful imaging modality for UCOGCP diagnosis.
