CT diagnostic value of adrenal ganglioneuroma / 中华放射学杂志

ABSTRACT

Objective To explore the dynamic spiral CT findings of adrenal ganglioneuromas and to evaluate its clinical value.Methods All 7 cases patients with adrenal ganglioneuromas confirmed by surgical pathology underwent spiral CT plain scanning and two phases dynamic enhancement scanning before operation.The CT images were reviewed and analysed retrospectively in comparison with surgical and pathological results.Results Six of 7 lesions were located in the right adrenal gland,1 in the left.The diameter of the tumors was 3.7—7.5cm,with a mean diameter of 4.6cm.The CT value of the plain scans, AP phases and PVP phases was 16.2—31.7 HU(with a mean value of 24.3 HU),20.9—36.6 HU(with a mean value of 30.2 HU),and 27.4—45.5 HU(with a mean value of 36.0 HU),respectively.The masses were well defined and showed a tendency of wedging into the space between the adjacent organs and structures and encasing the large vessels such as IV,but didn't compress or occlude them.Conclusion The dynamic SCT features of adrenal ganglioneuromas were obvious,dynamic SCT scans could suggest the diagnose.
