Computer tomography (CT) in the diagnosis of tumors of surrenal gland - A propose of 55 cases

ABSTRACT

A retrospective study on 55 subjects with surrenal gland tumors diagnosed by CT showed that the tumors are commonly benign and pheocromocytoma was detected lately with a large size (> 3 cm, accounted for 73.5%). Heterogenous structure of the tumors before and after the injection of the contrasts showed characterustic sign of pheocromocytoma. The CT procedure has had a sensitivity of 100% and a positive predictive value of 89%. In the diagnosis of ganglion metastasis, these ratios were 2/3 and 99% respectively, in the evaluation of infiltration into the liver and the right kidney, these ratios were 58.30% and 95% respectively
