Adrenal pseudocysts account for ~40% of adrenal cysts and are more likely than simple adrenal cysts to be symptomatic.
Pseudocysts do not have an epithelial lining and typically arise after an episode of adrenal hemorrhage. There is an ~7% association with malignancy (e.g. from hemorrhage into a cystic adrenal neoplasm) 6.
Adrenal pseudocysts appear as a simple cyst or may have a complicated appearance (i.e. septations, blood products, or a soft-tissue component).

Calcification may be present 4. Usually, there is no enhancement post contrast.
