Abstract
Solitary fibrous tumor (SFT) is an extremely rare tumor of the pancreas. The content of stromal tissue in the pancreas is insignificant, this fact explains the extremely rare occurrence of mesenchymal tumors (less than 1% of pancreatic neoplasms). It has been described only 16 such cases in the world literature.
A clinical case of solitary fibrous tumor of the pancreatic head of a man 43 years old, illustrating the difficulty of diagnosis is presents in the article/ In order to emphasize difficulties in diagnostics we introduce you another clinical case of extrapleural solitary fibrous tumors of the retroperitoneal space of a woman 63 years old.
Pancreatic SFT and NEN cannot be reliably differentiated on the basis of lesion structure and contrast medium uptake. However, in most cases SFT will progradiently enhance due to abundant collagen stroma, leading to marked difference between delayed-phase images of SFT and NEN with cystic degeneration. SFT is a rare tumour and radiologist should be aware of its characteristics, particularly in the setting of NEN with cystic degeneration or atypical contrast uptake.
