Hepatic angiomyolipoma: contrast patterns with SonoVue-enhanced real-time gray-scale ultrasonography.
نویسندگان
چکیده
This study was conducted to retrospectively evaluate the pattern of contrast enhancement with SonoVue on gray-scale ultrasonography of hepatic angiomyolipoma (HAML). Imaging features of 33 pathologically proven HAML lesions in 33 patients who underwent baseline ultrasound and contrast-enhanced ultrasonography (CEUS) were assessed retrospectively. All lesions were enhanced in the arterial phase and showed whole-tumor filling in. Thirty-two of 33 (97%) lesions showed early positive enhancement in the arterial phase. Twenty-three of these exhibited isoechoic or hyperechoic features in the portal phase. HAML demonstrate characteristic manifestations with SonoVue-enhanced real-time gray-scale ultrasonography.

Contrast-enhanced ultrasonography with a new contrast agent (SonoVue®) for characterization of renal tumors
Due to the increased use of imaging techniques such as ultrasound and computed tomography, an increasing number of renal tumors are being diagnosed incidentally. These tumors are often smaller and in an earlier stage, and it is difficult to distinguish benign from malignant tumors. The purpose of this study was to evaluate the value of Contrast-Enhanced Ultrasonography (CEUS) in the characteriz...
متن کاملContrast-enhanced ultrasonography of the liver using SonoVue
This review focuses on the use of contrast-enhanced ultrasonography (CEUS) with SonoVue (Bracco Imaging) for the diagnosis of focal liver lesions (FLLs), guidance during ablative treatment, and follow-up of liver tumors. Multicenter trials have shown that the performance of CEUS for the characterization of FLLs is similar to that of contrast-enhanced computed tomography or contrast-enhanced mag...

BACKGROUND Ultrasonography performed shortly after a direct or indirect muscle trauma may be confusing. The extent of a muscular tear can be difficult to assess because of oedema, intramuscular haematomas and red infarct. The aim of this study was to find out if it is possible to assess the extent of muscular lesions shortly (6 to 48 hours) after a trauma with improved accuracy using contrast-e...

INTRODUCTION A hepatic angiomyolipoma is a rare benign tumor of the liver composed of a mixture of smooth muscle cells, blood vessels and a variable amount of adipose tissue. Differentiating them from malignant liver tumors can often be very difficult. CASE PRESENTATION We report the case of a 43-year-old Caucasian man presenting with a large liver mass in the right lobe. The results of magne...
متن کاملCD68-Positive Cells in Hepatic Angiomyolipoma.
Four resected specimens of hepatic angiomyolipoma in which uptake of Sonazoid was observed in the postvascular phase of Sonazoid-enhanced ultrasonography were analyzed. Macrophage localization in the tumor was revealed pathologically by immunohistochemical staining for CD68. CD68-positive cells were observed in the tumor in all cases. The density of CD68-positive cells was 100/mm2, and the rati...
