Serous cystadenoma mimicking cystic pancreatic neuroendocrine tumor on 68Ga-DOTATOC PET/CT

Increased Uptake in Microcystic Serous Cystadenoma Mimicking Pancreatic Neuroendocrine Tumor on 68Ga-DOTATATE PET/MRI

“…This indicates that PET/CT is helpful in the diagnosis of pancreatic neuroendocrine tumor when tumor uptake of 68 Ga-DOTA somatostatin analogs is observed. But false-positive results can also occur, as demonstrated by serous cystadenoma of the pancreas with 68 Ga-DOTATOC PET/CT uptake, as reported previously 5–7 . The current case showed that a pancreatic serous cystadenoma may display moderate 68 Ga-DOTATATE uptake at the edge of the lesion on PET/MRI.…”

“…But false-positive results can also occur, as demonstrated by serous cystadenoma of the pancreas with 68 Ga-DOTATOC PET/CT uptake, as reported previously. [5][6][7] The current case showed that a pancreatic serous cystadenoma may display moderate 68 Ga-DOTATATE uptake at the edge of the lesion on PET/MRI. The superior soft-tissue resolution of MRI is able to reveal the high fluid content of serous cystadenoma, especially in DWI.…”
