Chronic liver disease is a major disorder worldwide. A better understanding of anatomy, blood flow, and pathophysiology may be a key issue for their proper management. Ultrasound (US) is a simple and non-invasive diagnostic tool in the abdominal field. Doppler mode offers real-time hemodynamic evaluation, and the contrast-enhanced US is one of the most frequently used modalities for the detailed assessment. Further development in digital technology enables three-dimensional (3D) visualization of target images with high resolution. This article reviews the wide ranges of application in the abdominal US and describes the recent progress in the diagnosis of chronic liver diseases.

PURPOSE: The purpose of this study is to evaluate the radiologic features and clinical utility of ultrasonography and mammography in cases of gynecomastia. MATERIALS AND METHODS: This study involved 40 men inwhom gynecomastia had been pathologically diagnosed by surgical incision. In 21 cases, a retrospective analysis of ultrasonographic and mammographic findings was performed. RESULTS: Causative factors of gynecomastia among the 40 pathologically-proven cases were idiopathic or pubertal in 33 cases, related to male hormone deficiency in three cases and to chronic liver disease in four. Bilateral involvement was seen in 14 cases, and unilateral involvementin 26 ; among unilateral cases, right side was involved in 10 cases, and the left side in 16. Mammographically, asubareolar discoid lesion was present in 12 cases, diffuse increased breast density was seen in five cases and dendritic marginated subareolar lesion without microcalcification in one. Ultrasonographically, a round smooth marginated low echogenic lesion in the subareolar region was seen in five cases, a diffuse hyperechogenic pattern without definite mass in two cases and an ill defined low echogenic lesion in one. CONCLUSION: The male breast is small, so in cases of gynecomastia, ultrasonography is an effective diagnostic modality. Mamography will, however, be helpful in the detection of microcalcification in cases of gynecomastia seen on sonography.

Adrenal cysts are a rare disease, and its prevalence is reported to be 0.06~0.18%. Its frequency of being recognized is increasing due to the widespread use of ultrasonography and computed tomography (CT) scans. We report here on a case of adrenal cyst that was mistaken as biliary cystadenoma prio-ocation and features. Laparoscopic exploration was performed via the transabdominal approach and this revealed a right adrenal cystic mass in the retroperitoneum beneath the liver (segment IV). We present here a case of adrenal cyst with endothelial lining along with a review of the literature to address the clinical presentation, histology, imaging features and differential diagnosis of this interesting and rare entity.

Fibrolamellar hepatocelluar carcinoma is a distinct clinicopathologic variant of hepatocellular carcinoma. We describe here the sonographic and CT findings of fibrolamellar hepatocellular carcinoma in a 17-year-old patient that mimicked hepatic malignant lymphoma due to the multiple small hypoattenuating nodules and extensive lymphadenopathy that we observed. We also include a review of the relevant literatures.

Ultrasound is a non-invasive, real-time, inexpensive, radiation-free and easily repeatable method, usually used for liver imaging. In recent years, new ultrasound examination techniques for liver diseases such as contrast-enhanced ultrasound and elastography have been rapidly developed, which can effectively identify intrahepatic space-occupying lesions, assess the degree of liver fibrosis and portal hypertension, and monitor the effects of treatment. Therefore, these technologies play an important diagnostic role in clinical liver diseases and have therapeutic interventional value. This guideline classifies the instrument set-up, patient preparation, and physician examination methods through multimodal ultrasound examinations (gray-scale ultrasound, color Doppler ultrasound, contrast-enhanced ultrasound, elastic ultrasound) for liver diseases. In addition, liver diseases multimodal ultrasound technology diagnostic criteria for diffuse hepatic lesions (inflammatory lesions, fibrosis, and sclerosis), multiple space-occupying lesions, and interventional procedures have been defined and standardized. Concurrently, we also recommend the ultrasound monitoring time interval and diagnostic report writing standard for liver diseases.
