[The role of computer tomography in differential diagnostic of incidentalomas adrenal glands].
[adrenal incidentaloma]
The possibilities of computer tomography (CT) for differential diagnosis of adrenal incidentalomas (AI) were investigated. CT was done for 157 patients with AT: 17--with malignant adrenal tumors (MAT) and 70--with benign adrenal tumors (BAT) (61--adrenocortical adenoma, 5--cyst, 3--hematoma, 1--myelolipoma). CT--main method of topic diagnostic for AI, which allow to make assumption about potential malignancy AI in 76.5% patients. Incidentalomas size more than 10,1sm, irregular contours, density more +51HU, signs of invasion, lymphadenopathy, regional or remote metastasis are the diagnostic criteria for MAT. In 23.5% cases with CT impossible to differentiate the malignant nature of AI. 10.0% patients with BAT had a false positive results, which slightly limits the diagnostic value of CT.
