Abstract:
Objective To describe CT and MR apearance of retroperitoneal ganglioneuroma .Methods CT and MR findings ofretroperitoneal tumor in a patient with ganglioneuroma biopsy-proved were retrospectively analyzed,and a literature review was conducted. Results The mass was well-circumscribed,non-enhanced CT showed homogeneous low atenuation, and a punctate calcification was seeninside tumor.Contrast uptake was delayed.Progressive but incomplete enhancement was observed.On MRI,T_2WI showed a high signalintensity and T_1WI show a low signal intensity.Enhanced MR depicted the mild enhancment.Conclusion Retroperitoneal ganglioneuroma is a rare tumor which should nevertheless be included in differential diagnosis of retroperitoneal masses when presenting as a well-delimitedtumor with possible tendency to surroud or displace major blood vessels.Low density on non-enhanced CT,and delayed progressiveenhancement on CT and MRI.
