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

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. F-FDG PET/CT revealed a solid mass measuring 1.

A rare case of pulmonary malignant granular cell tumor detected with 18F-FDG PET/CT imaging.

Malignant granular cell tumor is rarely involved in the lungs. We present a rare case with 18F-FDG PET/CT images showing a hypermetabolic lesion in the lower lobe of the left lung with posterior mediastinum invasion. Histopathologic study proved it as malignant granular cell tumor.
