Patient Data
Case Discussion
An ultrasound performed eight years earlier (images not available) showed a similar slightly smaller cystic lesion in the right adrenal region.
Adrenal cysts are rare. Usually they are benign.
In 1966, Dale G Foster subclassified adrenal cysts into four main types based on histopathological evaluation of 115 cases: epithelial cysts, parasitic cysts, especially hydatid, pseudocysts and endothelial cysts. In this series, endothelial cysts were the commonest type. Although other studies since have found pseudocysts to be more common 2.
It was decided that since the cyst in this case was an incidental pick up and the patient was not symptomatic from it to manage it conservatively. Therefore the exact type of cyst has never been ascertained.
