title: Large adrenal pseudocyst.
abstract: Cystic lesions of the adrenal gland are rare entities. Pseudocysts account for 40% of all cystic tumors of the adrenal glands, and are a consequence of hemorrhage and degeneration. Clinical signs are aspecific. On US and CT, a well defined large mass with cystic appearance is found. Thickening and irregularity of the cystic wall areas of different attenuation values within the cyst and central calcifications are due to hemorrhage. The more complex pseudocysts should be distinguished from cystic degeneration in adrenal malignancy and from cystic hypernephroma in the renal upper pole.
