analysis of this series of cases reveals the following points : complementary investigations ( computed tomography , magnetic resonance imaging ) sometimes suggest the diagnosis , the oncocytic nature is often a surprise pathological finding , it is difficult to determine whether the lesion is a pure oncocytoma and the exact grade can not be determined on frozen section , the choice between radical surgery and conservative surgery is made even more difficult , the study of the course of the disease raises the question of whether the term of oncocytoma should not be reserved to low grade tumours .
