CT of the adrenal gland: the many faces of adrenal hemorrhage.

Adrenal hemorrhage is rarely suspected clinically, exhibits no specific clinical symptoms or laboratory findings, and yet is immediately life-threatening when bilateral. Recognition of adrenal hematomas is complicated by the variable appearance of these lesions. We survey the ways in which adrenal hematomas can appear on CT and provide strategies for differentiating hematomas from other adrenal pathologies.
