Abstract:
PURPOSE: To determine the features of hepatic adenomatous hyperplasia using different imaging modalities. MATERIALS AND METHODS: 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.
