Abstract:
Objective To explore the imaging features and dynamic CT findings of primary adrenocortical carcinoma and evaluating its clinical value.Methods All 11 cases patients with primary adrenocortical carcinoma confirmed by surgical pathology underwent spiral CT plain scanning and two phases dynamic enhancement scanning before operation.Contrast injection was done by using nonionic Omnipaque at a flow rate of 3 ml/s with a power injector.The CT images were reviewed and analysed retrospectively in comparison with surgical and pathological results.Results Five of 11 lesions were located in the right adrenal gland,6 in the left.The diameter of the tumors was 4.1—16.0cm with 2 cases10.0cm.The attenuation of the plain scans,two phases contrast scans was 21.9—46.7 HU(with a mean value of 35.3 HU),30.5—65.8 HU(mean value 47.1 HU),and 52.6— 97.0 HU(mean value 74.2 HU),respectively.Four were in the shape of capsule,6 reticular,1 slightly inhomogeneous masses.The irregular tumor vessels of 6 reticular masses were seen in the artery phase. Conclusion The dynamic CT features of primary adrenocortical carcinoma were obvious,dynamic SCT scans could suggest the diagnose.
