Correlation of ultrasound findings with clinical pathological types of adrenal cortical tumors / 中华全科医师杂志

ABSTRACT

Objective To investigate the correlation between ultrasound findings and clinical pathological types of adrenal cortical tumors(ACT).Methods The clinical data and ultrasonographic finding of 138 ACT patients undergoing surgical treatment in Affiliated Hospital of Qingdao University from January 2006 to December 2015 were retrospectively reviewed.The correlation between ultrasonic signs and pathological types of ACT was analyzed with Spearman method.Results There were 65 males and 73 females aged 18-71 years old.Among 138 cases,90 patients were characterized by hypertension,Cushing signs,Coon signs and abnormal sexual character, with the clinical diagnosis of adrenal cortical hyperplasia or adenoma;while 48 asymptomatic patients were first detected by ultrasonography.The coincidence rate of ultrasound and clinical pathological diagnosis was 92.0%(127/138),and 11 cases were misdiagnosed.The coincidence rate of ultrasound and surgical diagnosis was 94.2%(130/138), and 8 cases were misdiagnosed.The coincidence rate for no functional adenoma was 95.8%(46/48), for cortisol cortical adenoma was 94.1%(32/34),for aldosterone cortical adenoma was 93.6%(29/31),for cortical cysts was 9/10,for no functional adenocarcinoma was 5/6,for sexual abnormal cortical adenocarcinoma was 3/4,for cortisol cortical adenocarcinoma was 2/3,for mucous cortical adenoma was 1/2.The diameter of ACT was 0.6-11.5 cm.The low echo nodules of the adrenal region with a diameter <2.0 cm were associated with aldosterone cortical adenomas(r=0.485, P=0.01); the low echo or isoechoic nodules with a diameter 2.0-5.0 cm were associated with cortical adenomas or non-functional adenomas(r=0.567,0.452,P=0.01),and the circular non-echo nodules were associated with cortical cysts(r=0.483, P=0.01); the irregular nodules with a diameter >5.0 cm were associated with cortical adenocarcinoma(r=0.595, P=0.01).Conclusion The ultrasound image of ACT is related to different clinical pathological types,which can provide important information for clinical diagnosis and selection of surgical modalities.
