Hemangiosarcoma of the adrenal glands: CT findings in two cases

Hemangiosarcomas of the adrenal gland, both benign and malignant, are excee dingly rare; only a dozen of them have been reported in literature to our k nowledge. We describe herein the findings at CT of 2 primary hemangiosarcom as of the adrenal glands. We also discuss their etiology, incidence, and di fferential diagnosis, particularly in relation to more frequent primary adr enal lesions, such as adrenal adenomas and carcinomas. CT will generally sh ow a heterogeneous mass with frequent necrosis, contrast-enhancement, and o ccasional calcifications. A prospective diagnosis cannot be made by imaging alone, and pathology represents the discriminating method for a correct di agnosis.
