OBJECTIVE. The purpose of our study was to retrospectively evaluate the sonographic, CT, and MRI findings (number, diameter, lobar location, depth from the hepatic capsule, and appearance of lesions) in a series of nine patients with pathologically proven solitary necrotic nodules of the liver and the natural'evolution at follow-up in four of the nine patients.
CONCLUSION. Solitary necrotic nodules are usually small, solitary lesions, mainly located under the liver capsule of the right lobe. They are hypoechoic on sonography, hypoat-tenuating on CT, have low signal intensity on both Tl- and T2-weighted MRI with lack of enhancement after IV contrast administration, and at follow-up have a tendency to show calcification and involution toward reduction in size.
