Adrenal Cortical Tumors with Low Attenuation Coefficients

Abstract

Four cases of adrenal tumors with unusually low attenuation coefficients are reported. The tumors presented with values ranging 8-17 EMI units (EU: 500 scale) instead of the expected 30-40 EU range of the remainder of adrenal tumors. Two of these patients had primary aldosteronism and 2 had Cushing''s syndrome. An unusually high lipid content may be responsible for the lucent appearance.
