[Vascular cysts of the adrenals. Association with aneurysm of the abdominal aorta].
A rare case of an adrenal vascular cyst associated to an abdominal aorta aneurysm is reported. Adrenal cysts are an uncommon clinical finding, in most cases incidentally discovered for nonspecific abdominal pain, during US, TC or RM evaluation or at autopsy. Small adrenal mass are clinically silent. They may be symptomatic (lumbar tension, pain) for dimensions over 10 centimetres. Cysts of large size can cause displacement and compression of adjacent organs. They present a difficult problem of differentiation between benign and malignant lesions. Non-neoplastic adrenal cysts have been divided into four categories: parasitic (7%), epithelial (9%), endothelial (45%) and haemorrhagic or pseudocystic (39%). Vascular adrenal cysts may be a traumatic consequence of an hamartomatous vascular anomaly. The aim of this paper is to discuss, on the basis of the literature, the etiology, diagnosis and treatment of the adrenal mass. Surgical timing is discussed for the concomitant vascular lesion. The elective treatment was left adrenalectomy performed through transperitoneal approach. Surgery for abdominal aorta aneurysm was differed because the adrenal mass was suspected to be an infected neoplastic lesion and for the feasibility of endovascular procedure. The adrenal specimens contained a cystic structure with fluid blood, fibrin and calcifications. Normal adrenal cortical tissue was found in the cystic wall. This lesion (arising from vascular anomalies) require separation from haemorrhagic adrenal neoplasm. Awareness of adrenal pseudocysts and careful attention to the hystological features aids this distinction.
