![]() Large symptomatic adrenal cysts should be surgically excised, but small, asymptomatic, non-functional cysts with benign characteristics may be treated conservatively with follow-up by ultrasound or computed tomography and biochemical evaluation. If an incidentally discovered adrenal lesion meets all the radiological criteria for an uncomplicated benign simple cyst, a conservative approach is recommended. ![]() The presence of solid components, thickened walls and septae increase the likelihood of a necrotic mass or infective cyst rather than a simple cyst. ![]() The lesions demonstrate the expected imaging characteristics of cysts, with fluid attenuation on CT, no enhancement following contrast administration, anechois on ultrasound and low T 1 and high T 2 signal characteristics on MRI ( Fig. These cysts can be categorised into five subtypes, summarised in Table 37.3. ![]() Autopsy series report an incidence of 0.06% and most adrenal cysts are detected incidentally but, when large, patients may present with flank pain.
