Abstract:
Objective To evaluate the localization of adrenal functionless tumor by ultrasonographv(US).Methods One hundred and six patients with adrenal functionless tumor were examined by US and subsequentlv proved by surgery and pathology.Results In 106 cases,true positive was 103,true negative,false positive and false negative were 1 each.The sensitivity,specificity and accuracy was 99.0%,50.0%and 98.1%,respectively.The adrenal tunctionless tumor tended increasing year by year.Tumors detected at very first by US were 77.9%.Tumor size distribution was gradually increasing as following: adenoma,pheochromocytoma(PHEO), neurilemmoma,myelolipoma,gangliocytoma and adenocarcinoma,in which there is significant difference.The myelolipoma presented charactersitically hyperecho feature to be easily distinguished from other tumors.The echo featLlres in the rest tumors chaotic echo.Conclusions US is a reliable examination of the first chdce for localizing diagnosis of adrenal functionless tumor and also helpful in differentiating histopathologically.
