Endothelial cyst of the adrenal gland: A rare case report.

Adrenal gland cysts are rare and uncommon manifestations. Mostly asymptomatic, discovered incidentally during radiological studies or at autopsy, or without characteristic symptoms. The spectrum of these entities may include benign cysts or malignant cystic neoplasms. They are classified into four types: pseudocysts, endothelial cysts, epithelial cysts, and parasitic cysts. Though pseudocysts are reported to be the most frequently clinically recognized adrenal cysts in surgical series, endothelial cysts are more frequent in autopsy series. Even with advanced imaging modalities, it is still difficult to differentiate a benign adrenal neoplasm from a malignant one. As a result, getting a definitive diagnosis and starting treatment is challenging. In both symptomatic and asymptomatic cases with a large diameter or increasing sizes during follow-up, or with any abnormality of adrenal hormones, surgery is the treatment of choice in symptomatic. Herein, we present a 47-year-old female with a nonfunctional left adrenal endothelial cyst, who was incidentally found during a computerized tomography scan. The patient presented with left-sided nephritic colic due to renal lithiasis. The objective of this paper is to recall the clinical characteristics and to specify the diagnostic contribution of imaging as well as the therapeutic modalities of this entity.
