“…Instead, we found a relatively slow accumulation of the contrast agent resulting in an isoechoic or hypoechoic CEUS pattern in the arterial phase. These results are in accordance with lymphoma infiltration of the liver and spleen where similar enhancement patterns were described [9,10].…”

“…Interestingly, renal lymphoma revealed a hypoechoic enhancement in the parenchymal phase in all cases, and again, this has been described for liver and splenic lymphomas in a very similar manner before [9,10]. Thus, our results show that lymphoma infiltration in different parenchymal organs display almost identical CEUS patterns.…”

“…Trenker et al [23] reported that HML had no specific tendencies in CEUS findings for the early vascular and post-vascular phases. In the present cohort, image findings in the early vascular phase of CEUS for the large group varied, while those for the small group nearly always showed an enhanced homogeneity and a washout pattern in the portal phase, and defect in the post-vascular phase.…”

Aim/Background: Evaluations of abdominal ultrasonography (US) findings of primary and secondary tumor-forming hepatic malignant lymphoma (HML) have not been adequately reported. In this study, we elucidated US and contrast-enhanced US (CEUS) findings in patients with HML. Materials/Methods: From January 2006 to March 2017, 25 patients with HML were enrolled (primary 7, secondary 18), each of whom was diagnosed pathologically. They were divided into 2 groups based on tumor diameter (cutoff, 30 mm). US imaging findings were retrospectively analyzed. Results: All tumors in patients with a small HML (<30 mm in diameter, small group, n = 14) were revealed as homogeneous hypo-echoic type (100%), with penetrating sign observed in only 1 patient. Tumors in 11 patients in the small group, examined with CEUS, showed homogeneous enhancement in the early vascular phase (91%) and a washout pattern in the portal phase (100%), and they were revealed as defective in the post-vascular phase (100%). In the large group (≥30 mm; n = 11), tumors were revealed as a heterogeneous hypo-echoic lesion in 10 (91%) and penetrating sign was observed in 8 (73%). Dilatation of the distal intrahepatic bile duct by the tumor was observed in 4 patients in the large group. In 7 large group patients examined with CEUS, imaging findings in the early vascular phase varied, with 5 (71%) showing a washout pattern in the portal phase and 5 (71%) revealed as defective in the post-vascular phase. Conclusion: We found that US imaging features of HML differ depending on the tumor diameter.

Background:Beside hepatocellular carcinoma, metastasis, and cholangiocarcinoma, the imaging findings of other relatively uncommon hepatic lesions are less discussed in the literature. Imaging diagnosis of these lesions is a daily challenge. In this article, we review the imaging characteristics of these neoplasms.Methods:From January 2003 to December 2014, 4746 patients underwent liver biopsy or hepatic surgical resection in our hospital. We reviewed the pathological database retrospectively. Imaging of these lesions was reviewed.Results:Imaging findings of uncommon hepatic lesions vary. We discuss the typical imaging characteristics with literature review. Clinical and pathological correlations are also described. Primary hepatic lymphoma consists only of 1% of the extranodal non-Hodgkin lymphoma, and is defined as the one involving only the liver and perihepatic lymph nodes within 6 months after diagnosis. Combined hepatocellular and cholangiocarcinoma (cHCC-CC) shares some overlapping imaging characteristics with both HCC and cholangiocarcinoma because of being an admixture of them. Angiosarcoma is the most common hepatic mesenchymal tumor and is hypervascular in nature. Inflammatory pseudotumor is often heterogeneous on ultrasonography and with enhanced septations and rims in the portovenous phase after contrast medium. Angiomyolipoma (AML) typically presents with macroscopic fat components with low signal on fat-saturated magnetic resonance imaging (MRI) and presence of drainage vessels. Intraductal papillary neoplasm of the bile duct (IPNB) is thought of as a counterpart to the pancreatic intraductal papillary mucinous neoplasm. Most of the IPNBs secrete mucin and cause disproportional dilatation of the bile ducts. Mucinous cystic neoplasm (MCN) contains proteinaceous and colloidal components without ductal communication and characterizes with hyperintensity on T1-weighted imaging. Other extremely rare lesions, including epithelioid hemangioendothelioma and inflammatory pseudotumor-like follicular dendritic cell sarcoma, are also discussed. Hepatoblastoma and mesenchymal hamartoma, mostly in children, are also briefly reviewed as well.Conclusion:It is important for radiologists to be familiar with the typical imaging features of the uncommon hepatic neoplasms. If imaging findings are not typical or diagnostic, further biopsy is required.
