Inflammatory pseudotumour of the liver: the residuum of a biliary cystadenoma?
Inflammatory pseudotumour is a rare form of a liver mass. We report the case of a 28-year-old man presenting with obstructive jaundice, in whom an inflammatory pseudotumour arose with the resolution of a mucus secreting cystic liver lesion. The initial features suggested an intrahepatic cystadenoma or cystadenocarcinoma, which on its involution left a solid mass. Histopathology showed an inflammatory pseudotumour with no evidence of malignancy. A similar case has been reported recently, with the development of an inflammatory pseudotumour following collapse of a liver cyst seen on imaging. These two cases may shed some light on the origins of these rare liver lesions.
