Cystic tumors of the adrenal gland are uncommon, but are being increasingly more frequently diagnosed during routine radiological evaluation as "incidentalomas". We discuss the differential diagnosis, therapeutic approach and the existing controversies concerning the management of this tumor type.Two additional cases of adrenal pseudocyst in two women aged 47 and 38 years are presented. In one case the tumor was discovered incidentally, whereas the other case presented with acute pain arising from intracystic hemorrhage.The fist patient had a cystic tumor of 8 cm with some inner walls. Fine needle aspiration biopsy revealed a benign cystic lesion of the right adrenal gland. At laparotomy, an 8.5 x 4.5 cm multiloculated cystic lesion was excised. The second patient presented with abdominal pain due to intracystic hemorrhage. A Doppler US did not disclose any vessel inside the lesion. We performed a lumbotomy and excised a 7.5 x 6 cm cystic tumor located in the right adrenal gland. Both lesions were diagnosed as adrenal pseudocyst; the second case was a hemorrhagic one.The therapeutic approach in adrenal cystic tumors can be based upon the radiological and cytological findings since malignant cystic tumors are uncommon. A clear liquid and a negative cytology practically discard malignant tumors. Furthermore, cystic adenocarcinomas are usually large and the cystic liquid is cloudy with abundant cellularity. Surgical treatment is justified in the symptomatic, big or complex tumors (mixed, non-homogeneous).
