endothelial cysts (most common), 45%; epithelial cysts, 9%; pseudocyst/haemorrhagic, 39% and parasitic cysts, 7%.
In this particular case, the adrenal cystic mass could have resulted from (1) the parasitic infection itself affecting a normal gland, (2) secondary cystic degeneration of an infected adenoma, or (3) infection of a primary endothelial cyst.
CT demonstration of a giant adrenal endothelial cyst of the angiomatous subtype.
1-6 Histologically, adrenal cysts have been classified into four groups: 1- Pseudocysts (39%) 2-Parasitic cysts (7%) 3- Epithelial cysts (9%) 4- Endothelial cysts
(45%), the latter are subdivided into angiomatous and lymphangiomatous cysts.
are the most common pathologic subtype of adrenal cyst, accounting for approximately 40% of adrenal cysts.
