There are a multitude of cystic lesions of the pancreas. Many have been given more than one name/term over the years resulting in confusion. One such tumour is the solid pseudopapillary tumour of the pancreas - in 1996 the WHO asigned this name for clarification in the histological classifications. Originally described by Franz in 1959, its origin name was a Franz-Gruber tumour.
It has a number of imaging characteristics, as well as demographic aspects common to this rare pancreatic tumour.
Solid pseudopapillary tumour of the pancreas is typically large at presentation ( 10cm on average ), has a proponderance for the tail of pancreas and contains both solid and cystic components. It has a enhancing capsule, may contain haemorrhagic components and in less than 10% contains calcification.
