ABSTRACT
PURPOSE:
To determine the features of hepatic adenomatous hyperplasia using different imaging modalities. MATERIALS ANDMETHODS:
Twenty-two patients with 29 adenomatous hyperplastic nodules of the liver (0.9-3.1 cm) underwent sonography (29 lesions), CT (24 lesions), angiography (11 lesions), MR (12 lesions), and Lipiodol CT(seven lesions). Each lesion was analyzed for echogenicity, attenuation, vascularity, signal intensity, and Lipiodol uptake.RESULTS:
On sonograms, echogenicity was high in 16, low in 11, and iso- in 2 of 29 lesions. On contrast enhanced CT scans, attenuation was high in 4, low in 14, and iso- in 6 of 24 lesions. On hepatic angiograms, vascularity of lesions was avascular in 9 and slightly vascular in 2 of 11 lesions. On MR images, signal intensity was high in 11 and iso- in 1 of 12 lesions on T1-weighted MRI, and iso- in 7, and low in 5 of 12 lesions on T2-weighted MRI. On iodized-oil CT scans, retention of Lipiodol was present in 3 and absent in 4 of seven lesions.CONCLUSION:
Common imaging findings of adenomatous hyperplasia of the liver are high echogenicity on sonography, low attenuation on CT, hypovascularity on angiography, high signal intensity on T1-weighted MRI, and iso- or low signal intensity on T2-weighted MRI.
