[CT findings in bilateral adrenal enlargement]

CT findings in ten patients with bilateral adrenal enlargement (six cases of adrenal metastasis, two cases of malignant lymphoma, one case of pheochromocytoma and one case of adrenal hemorrhage) reviewed. Four of six cases of adrenal metastasis showed asymmetrical adrenal enlargement on initial CT scans. Ring enhancement on postcontrast CT was recognized in one case of adrenal metastasis and one case of adrenal hemorrhage (subacute stage). Ring enhancement in the case of adrenal hemorrhage was more clear and smooth than that in the case of adrenal metastasis. One case of malignant lymphoma and one case of adrenal hemorrhage had Addison's disease.
