ABSTRACT
To study the clinical and pathological features of hepatocellular adenomas.History and comprehensive imaging features in 6 patients with confirmed hepatocellular adenomas were reviewed retrospectively and correlated with pathological findings.The results showed that all six patients had solitary adenomas. Of the 6 patients, 4 were men and 2 were women. The diameter of tumors ranged from 4 to 11 centimeters, with an average of 8.5 centimeters. All the adenomas were hypervascular, and were nearly isoattenuating to normal liver on nonenhanced, portal vein period and delayed images except for areas of necrosis, hemorrhage, or focal fatty degeneration. Six lesions showed heterogeneously high signal intensity on T1 weighted images of MRI. All tumors were resected completely, and there were no serious complications and death. It suggested that these tumors may have some common features on CT and MRI images that should allow us to improve our diagnostic ability, if we could contrast imaging features with pathological characters. The surgical operation is effective.
