CT diagnosis of Ganglioneuroma

Objective:To investigate the diagnosis of ganglioneuromas on CT.Methods:To review the CT imaging findings of 4 cases of ganglioneuromas confirmed by histopathology,and to analyze and discuss the characteristics of the ganglioneuromas with reviewing the literatures.Results:Ganglioneuromas mainly located paravertebrally or in adrenal gland,diameter larger than 3.5 centimeter.They were round or oval in shape,well circumscribed,homogeneous or slightly heterogeneous hypodense on plain scan.Most lesions showed spotty calcification and slightly homogeneous or heterogeneous enhancement.Conclusion:Ganglioneuroma has some specific characters on CT.CT is useful to diagnose the ganglioneuroma about the location and nature.
