Hypo-echogenic pseudolesions of the liver examined by CT.
Successive hypo-echogenic focal lesions of the liver tentatively interpreted sonographically as benign were collected over a 3-year period and analyzed. All of these patients had undergone a CT examination and had been followed up. Lesions ranging in size from 2 to 13 cm were seen in about 0.1% of the patients. None of the 16 homogeneous hypo-echogenic nonexpansive and well-demarcated lesions bordering upon anatomic structures with a partly straight or concave contour turned out to be malignant. CT was able to give little additional information.
