Adrenal cyst (AC) are rare lesions with heterogeneous origin. The most common type are
endothelial cysts, followed by pseudocysts, epithelial and parasitic cysts. Malignant and
functional adrenal tumors should be included in the differential diagnosis of AC as they
can radiologically present as cystic lesions.
The size of the AC determines their clinical presentation. Small AC are clinically silent.
Large AC presents with signs and symptoms either due to mass effect or intracystic
haemorrhage.
