Ultrasound Imaging of Hepatocellular Adenoma Using the New …
2017年11月15日 · Here we review the new classification scheme and discuss the corresponding features on contrast-enhanced ultrasound imaging. Hepatocellular adenoma (HCA), or hepatic adenoma (HA), is a benign epithelial tumor of the liver (Ishak 2001). It is typically diagnosed in women younger than 50 y of age.
Hepatic Adenomas: Imaging and Pathologic Findings
2001年7月1日 · Most adenomas are not specifically diagnosed at ultrasonography (US) and are usually further evaluated with computed tomography (CT) or other imaging modalities. Color Doppler US may help differentiate hepatocellular adenoma from focal nodular hyperplasia.
Hepatocellular Adenoma (Hepatic Adenoma) Imaging - Medscape
On ultrasound, hepatic adenomas demonstrate variable echogenicity (see the first image below). The lesions may be hypoechoic, isoechoic, or hyperechoic relative to liver parenchyma....

2018年10月10日 · Since contrast-enhanced ultrasonography (CEUS) is nowadays a well-established technique for liver nodule characterization, the aim of our study was to assess CEUS features of HCAs to identify criteria that correlate with different HCA subtypes as compared to histopathologic examination and other imaging modalities.
Hepatocellular Adenoma: Evaluation with Contrast-Enhanced Ultrasound …
2012年7月2日 · To review the contrast-enhanced ultrasonographic (CEUS) and magnetic resonance (MR) imaging findings in 25 patients with 26 hepatocellular adenomas (HCAs) and to compare imaging features with histopathologic results from resected specimen considering the new immunophenotypical classification.
Hepatocellular adenoma: color Doppler US and pathologic …
1994年3月1日 · PURPOSE: To describe the color Doppler ultrasound (US) features of hepatocellular adenoma (HA) and correlate these findings with pathologic findings, with special emphasis on the blood vessels. MATERIALS AND METHODS: Color Doppler US was prospectively performed in eight patients with histologic proof of HA.
Ultrasound features of hepatocellular adenoma and the
This study aimed to evaluate the characteristic features of HCA by conventional ultrasound and contrast-enhanced ultrasound (CEUS) findings. Methods: Twenty-six patients (10 males and 16 females; mean age 36.2+/-5.0 years) with 26 histopathologically proven HCAs were retrospectively identified.
