[Prevalence of adrenal incidentaloma at computed tomography (chest and abdominal) in a general hospital in Brazil].

Patients And Method: A cross-sectional prospective study was performed to evaluate 3,382 consecutive patients with no known adrenal disease or malignancies who underwent chest and abdominal CT scans over a ten-month period.
