Purpose: Adrenal incidentalomas (AIs) are adrenal masses, which are found on imaging studies not performed related to an adrenal problem. Hepatic incidental masses and renal incidental masses are usually seen in abdominal imaging methods. We aim to investigate the frequency and the kind of hepatic and renal incidental masses in patients with AIs.
Methods: Retrospective evaluation of 381 (245 female and 136 male) AI patients and 285 (168 female and 117 male) controls were done. Adrenal masses were divided into two groups according to Hounsfield Units (HU) ≤10 and >10, also classified as right, left and bilateral sided. The comparisons were made between hepatic and renal and both hepatic and renal incidental masses in AIs patients.
Results: Renal incidental mass and both hepatic and renal mass frequency were found higher in AIs group than controls. InAIs patients who had left sided unilateraladrenal mass HU >10, the frequency of both hepatic and renal incidental mass was found more than left sided unilateral adrenalHU ≤10 group (P=0.001). Also in patients who had bilateral sided adrenal mass HU >10 the frequency of both hepatic and renal incidental mass was found more than bilateral sided unilateral adrenal HU ≤10 group (P=0.049).
Conclusions: Increased incidence of both hepatic and renal incidental masses were detected in AIs patients which adrenal mass HU greater than 10. We consider that the physicians should carefully evaluate these cases. Large studies are needed to define the incidence and follow-up of AIs patients with hepatic and renal incidentalomas.
