Introduction: The aim of this study was to evaluate the feasibility and usefulness of supersonic shear wave elastography (SSWE) in the diagnosis of nonmalignant adrenal masses.

Material and methods: 13 patients with a total number of 16 adrenal masses were enrolled in the study. In each case, both conventional ultrasound imaging and SSWE for stiffness assessment were performed. The final diagnosis was based on CT, MRI, biochemical studies, surgery or more than one year of follow up.

Results: The final diagnosis: nodular hyperplasia in six masses, six adenomas, three cysts, and one myelolipoma. All solid adrenal masses presented the elastography signal in contrast to cystic lesions that were devoid of it, as shear waves do not propagate through fluids.

Conclusions: SSWE is a feasible technique that can be applied during ultrasound of the abdomen and retroperitoneum. SSWE presents potential for the differentiation of solid and cystic adrenal lesions. Further large scale studies evaluating the possibility of differentiation of adrenal and other retroperitoneal masses with SSWE are warranted. (Endokrynol Pol 2014; 65 (2): 119–124)
