Abstract
Benign vascular tumors, or hemangiomas, are common in young children. The most frequent way to identify them on the skin is as bright red surface lesions, although they can also be detected deeper as subcutaneous lesions. Visceral involvement, particularly of the liver, is commonly observed in patients with multiple cutaneous hemangiomas. Since most hemangiomas are self-limited, they can be clinically monitored. Despite this, hepatic hemangiomas can result in significant consequences, such as severe hepatomegaly, which can induce abdominal compartment syndrome, inadequate ventilation, and renal vein compression, as well as significant arteriovenous shunts that compromise the functioning of the heart. Depending on the patient's findings, management may range from routine follow-up to liver transplantation. Here, we present a case of hypothyroidism, hepatomegaly, and cardiac failure in a two-month-old female newborn with infantile hepatic hemangioma. The patient's symptoms were managed with the use of levothyroxine, propranolol, and transcatheter arterial embolization (TAE).

Abstract
An infantile hemangioma is a congenital benign tumor formed by the proliferation of vascular cells during the embryonic stage. It is more common in the skin but can also occur in the mucous membranes, liver, brain and muscle. Hepatic hemangioma appears to be a benign tumor; however, it may lead to poor outcomes because of severe complications, such as high-output cardiac failure. The main treatment of hepatic hemangioma in infants is oral drugs, such as propranolol and glucocorticoids, but the clinical response is not always satisfactory. We describe a rare case of a 2-month-old boy who presented with infantile cutaneous and hepatic hemangiomas. By using dermoscopy and observations of the abdominal color Doppler ultrasound, after 9 months of oral treatment with itraconazole solution, the infantile cutaneous hemangioma complicated with hepatic hemangioma was eventually cured. There was no liver or kidney function damage during the whole treatment period. Itraconazole oral solution for the treatment of infantile cutaneous hemangioma complicated with hepatic hemangioma showed good efficacy, compliance, and safety in this case.

Abstract
Background Infantile hepatic hemangioma (IHH) is a common vascular, fast-growing hepatic tumor that is usually accompanied by multiple cutaneous hemangiomas. Diffuse IHH (DIHH) is a rare type of IHH that exhibits many tumors with nearly complete hepatic parenchymal replacement. At present, there is no specific standardized treatment plan for DIHH. Herein, we present the case of a 2-month-old girl with DIHH and without cutaneous hemangioma who achieved complete remission after undergoing propranolol monotherapy. Case presentation The infant with low birth weight was presented to the pediatric department with a 2-month history of persistent vomiting and feeding difficulty. Ultrasonography and abdominal magnetic resonance imaging revealed hepatomegaly and diffused intrahepatic lesions. A computed tomography-guided percutaneous liver biopsy was performed, and the pathological examination suggested the diagnosis was DIHH. The patient exhibited remarkably response to an increasing dose of oral propranolol, from 0.5 mg/kg to 2 mg/kg every day. The intrahepatic lesions were almost completely regressed after one year of treatment and no distinct adverse reaction was observed. Conclusion DIHH can induce life-threatening complications that require prompt interventions. Propranolol monotherapy can be an effective and safe first-line treatment strategy for DIHH.

Abstract
BACKGROUND Hepatic hemangiomas may be associated with serious complications; however, it is unknown whether ultrasound (US) features can predict complications. OBJECTIVE To analyze initial US features of hepatic hemangiomas predictive of complications. MATERIALS AND METHODS This is a single-center retrospective cohort study of clinical, biological, and imaging data of infants with hepatic hemangioma between 2000 and 2018. Patients were categorized as having or not having any complication(s). Associations between initial US features and complications were analyzed through logistic regression. Receiver operating characteristic (ROC) curve analyses were performed to determine optimal cutoff values for continuous variables. Stepwise forward logistic regression was used to construct risk prediction models with training and validation sets. Model calibration and discrimination were evaluated using Hosmer-Lemeshow tests, area under the ROC curve, and overall accuracy. RESULTS Of 112 infants with hepatic hemangioma, 67 (60%) had focal, 32 (28%) had multifocal, and 13 (12%) had diffuse lesions, with complication rates of 51%, 34%, and 92%, respectively, mostly cardiac (54/57, 95%). The US characteristics of the hemangiomas were diverse. Risk factors for complications included diffuse subtype; large tumor volume (focal forms); elevated peak systolic hepatic arterial velocity (PSV); and hepatic vein dilation. For focal forms, initial tumor volume >40 ml and PSV >100 cm/s had >70% sensitivity and specificity, respectively, to predict complications; a model including these variables had 75% overall accuracy in the validation set. For multifocal/diffuse forms, a PSV >115 cm/s had sensitivity and specificity to predict complications of >70%; a model including this variable had 78% overall accuracy in the validation set. CONCLUSION Diffuse subtype, large tumor volume, elevated hepatic arterial PSV, and hepatic vein dilation are risk factors for complications of hepatic hemangiomas.

Abstract
The World Federation for Ultrasound in Medicine and Biology (WFUMB) is addressing the issue of incidental findings (IFs) with a series of publications entitled "Incidental imaging findings-the role of ultrasound". IFs in the liver of newborns and children are rare and much less commonly encountered than in adults; as a result, they are relatively much more frequently malignant and life-threatening, even when they are of benign histology. Conventional B-mode ultrasound is the well-established first line imaging modality for the assessment of liver pathology in pediatric patients. US technological advances, resulting in image quality improvement, contrast-enhanced ultrasound (CEUS), liver elastography and quantification tools for steatosis have expanded the use of ultrasound technology in daily practice. The following overview is intended to illustrate incidentally detected liver pathology covering all pediatric ages. It aims to aid the examiner in establishing the final diagnosis. Management of incidentally detected focal liver lesions (FLL) needs to take into account the diagnostic accuracy of each imaging modality, the patient's safety issues (including ionizing radiation and nephrotoxic contrast agents), the delay in diagnosis, the psychological burden on the patient and the cost for the healthcare system. Moreover, this paper should help the pediatric clinician and ultrasound practitioner to decide which pathologies need no further investigation, which ones require interval imaging and which cases require further and immediate diagnostic procedures.

Abstract
Hepatic hemangiomas (HHs) are the most common benign liver tumors in infancy, but despite their frequent occurrence, their radiologic appearance may be particularly challenging to assess, owing to unique anatomical and development features that distinguish their subtypes in the pediatric population. There are 3 main patterns of the lesions recognized in HHs: focal, multifocal and diffuse. Medical care strategies range from simple observation to surgery, and a timely diagnosis is crucial to establish the most appropriated clinical management and therapy. Ultrasound (US) is typically the first level examination of pediatric vascular anomalies, able to meet a satisfactory diagnosis and has proved very helpful to assess for involution through serial imaging. CT and MRI are second-level methods seldom performed, offering an anatomical panoramic view and clarification when US is non-conclusive. Histologic confirmation is rarely required. HHs show a variable sonographic appearance, with hypoechoic (mostly) or hyperechoic solitary\multifocal mass and wide features. Hepatic vessels assessment reveals an abnormal flow, enlarged vasa, decreased resistive index (RI) values, scarce blood supply distally to lesions and hyper vascular regions inside them. In this pictorial essay, we review HHs subtypes in further details, illustrate US, CT and MRI findings and clarify a recurrent dispute over the existing terminology.

Abstract
OBJECTIVE Hepatic hemangiomas (HH) are the most common vascular tumors of the liver. It is important to distinguish hemangiomas from malignant liver tumors. MATERIALS AND METHODS The patients 0 to 1 years old, were diagnosed with HH and followed up in the oncology outpatient clinic between 2009 and 2020 were included in the study. RESULTS A total of 127 patients with the diagnosis of HH were included in the study. Of the patients, 99 (78%) had focal, 20 (15.7%) had multifocal, and 8 (6.3%) had diffuse HHs. Surgery was performed and the diagnosis was confirmed histopathologically in 6 patients (4.7%). During the follow-up, 16 (12.5%) patients received medical treatment. Thirteen (10.2%) were treated with propranolol, 2 (1.5%) with corticosteroids, and 1 (0.8%) with propranolol and corticosteroids. Complete response was obtained in 9 (9/16) patients and partial response was obtained in 6 (6/16) patients with medical treatment. CONCLUSION Although HH is a benign tumor, it is important to make its differential diagnosis with malignant tumors of the liver. Over the years, the need for histopathologic examination for diagnosis has decreased. The success rate of propranolol is high, and the need for other treatment options with a high side-effect profile has decreased significantly since 2008.

Abstract
Hemangiomas are the most common benign vascular neoplasms of infancy. Congenital hemangiomas proliferate in utero, and are fully formed at birth. They are usually solitary. Generalized forms are exceptional. The liver is the second most common site of hemangiomas after the skin. When >5 cutaneous hemangiomas are present, screening abdominal ultrasound is recommended. Based on the degree of liver parenchyma involvement, 3 hepatic hemangiomas’ subtypes are defined: focal, multifocal, and diffuse. Hepatic hemangiomas’ clinical presentation varies from asymptomatic to life-threatening. High output cardiac failure, consumptive coagulopathy, abdominal compartment syndrome, and liver dysfunction are possible complications. We report an unusual case of symptomatic congenital hemangiomatosis in a male infant born with innumerable generalized cutaneous hemangiomas whose screening abdominal ultrasound revealed multifocal hepatic hemangiomas with extensive mixed shunts. We aim to highlight this unique entity with severe associated complications and stress the role of imaging at initial presentation, for follow-up, and to guide therapeutic choices.

Abstract
Incidental liver lesions are identified in children without underlying liver disease or increased risk of hepatic malignancy in childhood. Clinical and imaging evaluation of incidental liver lesions can be complex and may require a multidisciplinary approach. This review aims to summarize the diagnostic process and follow-up of incidental liver lesions based on review of the literature, use of state-of-the-art imaging, and our institutional experience. Age at presentation, gender, alpha fetoprotein levels, tumor size, and imaging characteristics should all be taken into consideration to optimize diagnosis process. Some lesions, such as simple liver cyst, infantile hemangioma, focal nodular hyperplasia (FNH), and focal fatty lesions, have specific imaging characteristics. Recently, contrast-enhanced ultrasound (CEUS) was Food and Drug Administration (FDA)-approved for the evaluation of pediatric liver lesions. CEUS is most specific in lesions smaller than 3 cm and is most useful in the diagnosis of infantile hemangioma, FNH, and focal fatty lesions. The use of hepatobiliary contrast in MRI increases specificity in the diagnosis of FNH. Recently, lesion characteristics in MRI were found to correlate with subtypes of hepatocellular adenomas and associated risk for hemorrhage and malignant transformation. Biopsy should be considered when there are no specific imaging characteristics of a benign lesion. Surveillance with imaging and alpha fetoprotein (AFP) should be performed to confirm the stability of lesions when the diagnosis cannot be determined, and whenever biopsy is not feasible.

Abstract
Infantile hepatic hemangiomas (IHHs) are common benign tumors seen in the liver of infants. IHHs are true infantile hemangiomas (IHs) and have phases of proliferation and involution parallel to those of cutaneous IHs. The definition and classification of IHH are still confusing in the literature. The mechanisms during the pathogenesis of IHH have yet to be discovered. The clinical manifestations of IHH are heterogeneous. Although most IHH lesions are asymptomatic, some lesions can lead to severe complications, such as hypothyroidism, consumptive coagulopathy, and high-output congestive cardiac failure. Consequently, some patients can possibly encounter a fatal clinical condition. The heterogeneity of the lesions and the occurrence of disease-related comorbidities can make the treatment of IHH challenging. Oral propranolol is emerging as an effective systemic approach to IHH with obvious responses in tumor remission and symptom regression. However, the precise clinical characteristics and treatment strategies for patients with severe IHH have not yet been well established. Here, we summarize the epidemiology, pathogenic mechanism, clinical manifestations, diagnosis, and treatment of IHH. Recent updates and future perspectives for IHH will also be elaborated.

Abstract
OBJECTIVE The aim: To revise the case-series of hepatic vascular tumors (HVT), particularly to identify optimal visualization, management and role of surgical intervention. PATIENTS AND METHODS Materials and methods: Out of 96 children with hepatic tumors who hospitalized in a single center from 2011 to 2020, 20 (20,8%) were diagnosed HVT. Hepatic Hemangiomas (HHs) were presented in 19 patients and Kaposiform hemangioendotelioma (KHE) in one case. To determine the type of HH we used radiological classification. For visualisation contrast-enhanced MRI (n=7, 30%) and cCT (n=15,70%) were used. Follow-up period was 14-77 months. RESULTS Results: All HVT were revealed by sonogram at the age of 0-5 m, with 4 (20%) diagnosed prenatally. Male to female ratio was 3:2. Beta-blockers were prescribed to 12 patients with HHs. Treatment duration was from 6 to 24 month. Steroid therapy was initial in cases when it was impossible to prescribe the curative dose of beta-blockers. Complications of propranolol treatment were transitory bradycardia (n=7) and transitory hypoglycemia (n=2). After vincristine chemotherapy decreases the tumor size by 54%, that allowed a safe liver resection. 4 (20%) patients - two multifocal HHs, one diffuse HH and in patient with KHE manifested congestive heart failure and pulmonary hypertension Mortality rate is 5% (n=1), this patient died against progressive cardiovascular failure. CONCLUSION Conclusions: life-threatening complication of HVT was congestive heart failure. Early treatment is beneficial for complications prevention. Surgical treatment is optional for KHE when can be removed safely.

Abstract
Liver hemangiomas are benign vascular tumors of infancy. They can have vascular shunting mostly arteriovenous and sometimes arterioportal or portosystemic, which improves as hemangiomas involute. In contrast, congenital portosystemic shunts are developmental vascular anomalies that may go undetected for years, with significant sequelae. We describe a child with a history of multiple cutaneous and liver hemangiomas in infancy and later diagnosis of congenital portosystemic shunt. Past experience of a similar patient and a current baby followed for liver hemangiomas with portosystemic shunts, is also shared. Literature is reviewed for known association. We suggest longer-term follow-up for babies with liver hemangiomas.

Abstract
Infantile hepatic haemangioendothelioma (IHH) is the most common benign hepatic tumour in infants. However, experience of managing IHH is lacking and treatments for symptomatic IHH are controversial. Here we report the case of a patient with IHH treated by liver resection. A liver mass was found in a newborn by prenatal ultrasonography. The patient presented with abdominal distention with a tangible mass. Further imaging diagnosis and biopsy were carried out and complete surgical resection of the mass was performed. Histological examination confirmed IHH. The patient recovered uneventfully after surgery, with no additional therapy after discharge and no recurrence during follow-up. We also summarise previously published resected cases of IHH and review the surgical outcomes. Surgical resection and liver transplantation appear to be effective treatments for symptomatic IHH.

Abstract
Contrast-enhanced ultrasound (CEUS) is increasingly being used in children. One of the most common referrals for CEUS performance is characterization of indeterminate focal liver lesions and follow-up of known liver lesions. In this setting, CEUS is performed with intravenous administration of ultrasound contrast agents (UCAs). When injected into a vein, UCA microbubbles remain confined within the vascular network until they dissipate. Therefore, visualization of UCA within the tissues and lesions corresponds to true blood flow. CEUS enables continuous, real-time observation of the enhancement pattern of a focal liver lesion, allowing in most cases for a definite diagnosis and obviating the need for further cross-sectional imaging or other interventional procedures. The recent approval of Lumason (Bracco Diagnostics, Monroe Township, NJ) for pediatric liver CEUS applications has spurred the widespread use of CEUS. In this review article we describe the role of CEUS in pediatric liver applications, focusing on the examination technique and interpretation of main imaging findings of the most commonly encountered benign and malignant focal liver lesions. We also compare the diagnostic performance of CEUS with other imaging modalities for accurate characterization of focal liver lesions.

Abstract
Liver and biliary pathology in the neonate are rare and include a broad range of structural, neoplastic, infectious, genetic, and metabolic diseases. While most conditions present postnatally, antenatal detection is increasing given recent advances in antenatal imaging capabilities. In certain structural or obstructive liver diseases, antenatal detection now proves essential to help guide treatment and prevent morbidity. We review the epidemiology, pathophysiology, common antenatal diagnostic findings, and recommendations for surgical liver and biliary pathology in the neonate.

Abstract
Infantile hepatic hemangioma is the most common liver tumor in children. The most common symptoms are mass in her stomach, anemia and heart failure. According to the findings of the patient, the treatment may vary from the clinical follow-up to liver transplantation. In our study, the details of the surgical technique were presented. An 11-day-old newborn case with giant hepatic hemangioma causing postnatal respiratory arrest was presented in this study. Large and symptomatic patients with infantile hepatic hemangiomas who face us with different clinical behaviors are operated. It will be useful to share the surgical technique for these rarely seen cases for surgeons.

Abstract
PURPOSE Infantile hepatic hemangioendothelioma (IHHE) is the most common hepatic vascular tumor in children. We report on the treatment outcome of our large single-center experience of patients with IHHE over a 9-year period. MATERIALS AND METHODS A retrospective analysis of all IHHE patients treated at the Children Cancer Hospital Egypt from April 2008 through April 2017. RESULTS In total, 28 patients (18 females, 10 males) were diagnosed with IHHE with a median age at diagnosis of 3 months. The lesions were multifocal (n=12), focal (n=10), and diffuse (n=6). Six (21.4%) patients initially had low T3 and T4. Eleven patients did not receive any treatment, whereas 1 patient underwent resectional surgery. Sixteen patients received drug treatment, 9 of whom responded well to first-line propranolol/prednisolone, whereas 7 patients needed salvage treatment. Twenty-five patients are alive, whereas 3 patients have died. CONCLUSIONS Overall, patients with IHHE do well, a significant percentage of whom do not require drug therapy, particularly for those with small focal lesions. In patients with multifocal/diffuse disease, there is a high incidence of low T3 and T4 and while some of these patients did well without additional therapy, those with rapidly progressive lesions during treatment may do poorly.

Abstract
Infantile hepatic hemangioma (IHH) is a common vascular tumor, distinctive for its perinatal presentation, rapid growth during the first year of life, and subsequent involution. Although they generally follow a benign course, some tumors have been reported to undergo malignant transformation. The diagnosis of IHH is based on patient's medical history, physical examination, and imaging. Moreover, the management of this vascular tumor is based on clinical presentation and includes observational, medical, surgical, and radiological interventional treatment options. The present review presents the currently available data in the literature on the diverse aspects of the terminology, epidemiology, clinical presentation, pathogenesis, diagnosis, indications for surgery, malignant potential, and long-term outcomes of these tumors.Conclusion: No formal guidelines have yet been established for the treatment of these hepatic lesions, and the therapeutic strategies implemented vary widely from simple observation to medical, radiological, and surgical interventions in the prism of multidisciplinary teams.What is Known:• Infantile hepatic hemangioma is the most common benign tumor of the liver in infancy, but despite its benign nature, it can present with life-threatening complications.• The treatment strategies range from simple observation to a series of medical, surgical, and radiological interventions.What is New:• This review gives an overview of the developments and current status about the management of IHH.• The aim of this study is to clear up the confusion and controversy that exists about terminology, diagnosis, and treatment of IHH.

Abstract
OBJECTIVES To describe three cases of giant fetal hepatic hemangioma detected by prenatal ultrasound in the third trimester of pregnancy and further confirmed by fetal magnetic resonance imaging (MRI). An updated review of the literature was also carried out. RESULTS In one case, there was an unexpected intrauterine demise at 35 weeks. The other two women delivered liveborn infants at term. The first of these two neonates had a stormy neonatal course and underwent endovascular embolization with limited clinical success. The infant presented multiple medical complications and was discharged home at five months of age. The second infant had an uneventful postnatal course. Subsequent follow-up scans showed progressive shrinkage of the lesion with no associated complications. A review of the English literature revealed a total of 42 cases prenatally diagnosed by ultrasound. The most relevant clinical and ultrasound findings are presented and the diverse perinatal outcomes related to this condition are discussed. CONCLUSIONS Fetal hepatic hemangiomas are exceedingly rare vascular tumors; however, they can be associated with several life-threatening conditions. They are usually detected by ultrasound, either incidentally or in the context of nonimmune hydrops secondary to high-output cardiac failure. Our review documents the increasing role of fetal MRI in the prenatal diagnosis and management of these cases. However, the improvement in prenatal diagnostic imaging techniques has not been associated with a better perinatal prognosis in the reported cases.

Abstract
Mesenchymal tumors in childhood comprise benign and malign entities and differ regarding typical sites of manifestation, age peak and clinical symptoms. In some cases biopsy is mandatory. If nephroblastoma is a possible diagnosis, biopsy must be avoided by all means in order to avoid biopsy tract metastasis. Imaging is used to narrow the differential diagnosis, describe the exact extent of the lesion and deliver complete staging. In pediatric patients sonography and MRI are the most important imaging modalities. Low-dose CT of the thorax serves for assessment of possible pulmonary metastases.

Abstract
Proper nomenclature is a major obstacle in understanding and managing vascular anomalies. Often the same term is used for totally different types of lesions or, conversely, the same lesion may be labeled with different terms. Although in recent times there has been a greater understanding of the problems concerning vascular anomalies, episodes of improper use of terminology still remain. The aim of this article, starting from the most recent classification of vascular anomalies, is to provide a clinical and instrumental approach to identifying these lesions and to converge towards a clear and unambiguous terminology that must become univocal among the various operators to avoid diagnostic misunderstandings and therapeutic errors.

Abstract
Although liver tumors are rare in the pediatric population, they are common in the setting of children with specific risk factors requiring increased awareness and, in some instances, screening. The evaluation of a liver mass in children is largely driven by the age at diagnosis, the presence of any medical comorbidities, and initial testing with alpha fetoprotein and imaging. Specific guidelines for the management of different tumors have been implemented in recent years such that a multidisciplinary approach is ideal and care should be provided by centers with experience in their management.

Abstract
Magnetic resonance imaging (MRI) is commonly used to characterize focal liver masses in the pediatric population. MRI is the preferred modality because of its superior contrast resolution and utility for obtaining functional sequences such as diffusion-weighted imaging (DWI). MR exams performed with a hepatocyte-specific gadolinium-based contrast agent can characterize focal liver lesions, which helps in differentiating a common benign entity such as focal nodular hyperplasia from other liver pathology when the background liver is normal. The most common benign focal lesion is a hemangioma, and metastases followed by hepatoblastoma are the most common malignant lesions. This article can help radiologists become familiar with the pre- and post-contrast imaging features of common pediatric liver masses.

Abstract
A number of benign and malignant neoplasms may arise from the vascular elements within the liver parenchyma. Lesions discussed in this article include angiosarcoma, epithelioid hemangioendothelioma, solitary fibrous tumor (hemangiopericytoma), infantile, and cavernous hemangiomas. Despite a common theme of vascular origin, the pathologic and imaging appearance of these entities can be heterogeneous. Angiosarcomas are bizarrely enhancing, highly aggressive tumors, which often present with metastatic disease. When solitary, epithelioid hemangioendothelioma lesions can exhibit a concentric ring or target appearance on contrast-enhanced CT and at MR and when numerous may be indistinguishable from angiosarcoma except for a more slowly advancing course. Primary solitary fibrous tumors of the liver are exceedingly rare solid masses and most often initially diagnosed on imaging as other entities such as cholangiocarcinoma. Infantile hemangiomas consist of benign proliferation of the vascular endothelium and in the absence of flow-related complications, are usually clinically silent, and may be detected incidentally as T1 hypointense, T2 hyperintense, centripetally enhancing lesions. Cavernous hemangiomas are extremely common hepatic lesions and when classic rarely offer a challenge in diagnosis, though atypical variants may mimic more serious diseases. The purpose of this review is to provide an overview of important vascular tumors of the liver in order to aid the radiologist in providing a broad differential diagnosis for focal liver lesions, and when classic, suggest specific uncommonly seen diagnoses in order to more accurately guide clinical management.

Abstract
Hepatic hemangiomas are the most common benign liver tumor of infancy and are divided into two main types: rapidly involuting congenital hemangiomas (RICH) and non-involuting congenital hemangiomas. RICH typically involute by 12 months and are often asymptomatic. Surgical resection is rare. Indications for surgical resection include rupture, rapid growth, consumptive coagulopathy, and abdominal pain. We present two patients from different institutions who both developed clinically significant ascites as the RICH involuted, prompting surgical resection. This is a new indication for resection.

Abstract
OBJECTIVES To investigate the combined use of ultrasound together with clinical features to differentiate infantile hepatic hemangioma (IHH) from other focal liver lesions (FLLs) in children and to compare the efficacy of the combined method to that of CECT/MRI. METHODS The location, number, size and appearance of the tumors were evaluated in 45 children with IHH. Another 45 children with FLL were randomly selected as a control group. Independent factors for predicting IHH versus FLLs were evaluated. The diagnostic performance of the clinical and ultrasound features was compared with CECT/MRI. RESULTS Compared with the control FLL group, the IHH group had a younger age at diagnosis (P = 0.008), lower alpha-fetoprotein (AFP) levels (P = 0.000), smaller lesion sizes (P = 0.000), and a higher tumor proportion with a resistance index (RI) of <0.7. Multiple logistic regression analysis showed that age, size, RI and AFP were independent factors for predicting IHH. Receiver operating characteristic (ROC) curve analysis showed that the AUC (area under the curve) of the four combined independent factors was 0.881 (95% CI: 0.744-0.960), while the AUC for the CECT/MRI method was 0.905 (95% CI: 0.774-0.973), and the combined AUC for the independent factors and CECT/MRI was 0.929 (95% CI: 0.805-0.985). There were not statistically significant among the three AUCs (P > 0.05). CONCLUSIONS CECT/MRI was the effective diagnostic indicator for IHH. However, the combined clinical and ultrasound diagnoses, including age at diagnosis, lesion size, RI and AFP, can achieve the same effectiveness as CECT/MRI.

Surveillance Recommendations for Children with Overgrowth Syndromes and Predisposition to Wilms Tumors and Hepatoblastoma. Clin Cancer Res 2018; 23:e115-e122. [PMID: 28674120 DOI: 10.1158/1078-0432.ccr-17-0710] [Citation(s) in RCA: 109] [Impact Index Per Article: 18.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2017] [Revised: 04/23/2017] [Accepted: 05/09/2017] [Indexed: 12/13/2022]
Abstract
A number of genetic syndromes have been linked to increased risk for Wilms tumor (WT), hepatoblastoma (HB), and other embryonal tumors. Here, we outline these rare syndromes with at least a 1% risk to develop these tumors and recommend uniform tumor screening recommendations for North America. Specifically, for syndromes with increased risk for WT, we recommend renal ultrasounds every 3 months from birth (or the time of diagnosis) through the seventh birthday. For HB, we recommend screening with full abdominal ultrasound and alpha-fetoprotein serum measurements every 3 months from birth (or the time of diagnosis) through the fourth birthday. We recommend that when possible, these patients be evaluated and monitored by cancer predisposition specialists. At this time, these recommendations are not based on the differential risk between different genetic or epigenetic causes for each syndrome, which some European centers have implemented. This differentiated approach largely represents distinct practice environments between the United States and Europe, and these guidelines are designed to be a broad framework within which physicians and families can work together to implement specific screening. Further study is expected to lead to modifications of these recommendations. Clin Cancer Res; 23(13); e115-e22. ©2017 AACRSee all articles in the online-only CCR Pediatric Oncology Series.

Abstract
Propranolol was first used in 2008 to treat hemangioma; its efficacy and safety have since changed the classical treatment indications. Infantile hepatic hemangioma presents as a spectrum of clinical conditions varying from simple asymptomatic lesions to lethal complications. Tufted hemangioma and Kaposiform hemangioendothelioma are congenital vascular tumors that lead to Kasabach-Merritt syndrome. Hemangiomas, like pure arteriovenous malformations, can cause hyperdynamic heart failure, and diffuse nodular-type hemangiomas can present with hypothyroidism. Respiratory problems and hepatic failure can be associated with diffuse nodular-type liver hemangiomas. There is a spectrum of approaches to management, varying from "watchful waiting" to liver transplant. In the age of propranolol, there has been a prominent change in the infantile hepatic hemangioma treatment algorithm. Our suggestion is early treatment with 3 mg/kg/day propranolol plus 1.0 to1.5 mg/kg/day prednisolone in all patients. This protocol is the most effective strategy for type 3 infantile hepatic hemangioma. Approximately one-third of patients with abdominal compartment syndrome in the era before propranolol treatment required liver transplant; this new treatment obviates transplant for many of these patients.

Abstract
Screening of infants with five or more cutaneous infantile hemangiomas with abdominal ultrasound is often recommended. However, diffuse hepatic hemangioma can develop even in patients with single cutaneous hemangioma. This highlights the importance of physical examination and screening ultrasound in these patients.

Abstract
Space occupying liver lesions usually present with abdominal pain or abnormal physical findings, such as a palpable abdominal mass or distention. Liver lesions identified in children include benign and malignant neoplasms, inflammatory masses, cysts and metastatic lesions. Two-thirds of liver lesions in children are malignant. Hepatoblastoma accounts for two-thirds of malignant liver tumors in children. Benign lesions of the liver in children include vascular lesions, hamartomas, adenomas, and focal nodular hyperplasia. Although benign and malignant liver masses share some clinical manifestations, however treatment and prognosis differ. Evaluation involves physical examination, imaging evaluation and laboratory investigations such as serological markers [alpha-fetoprotein (AFP)] for malignant liver lesions. Ultrasound is the initial imaging modality of choice because it can detect, characterize, and provide the extent of liver lesions. However, CT or MRI are often subsequently performed for further characterization, assessment of precise extent, and detection of associated metastatic disease in cases of malignant hepatic neoplasm. Serological markers (such as alpha fetoprotein) can be useful in narrowing the differential diagnosis when they are markedly elevated but a substantial number of patients unfortunately do not have high levels of these markers at the time of presentation or cautious interpretation is warranted as AFP level is frequently elevated in infants up to 6 mo of age and may be slightly elevated with benign tumors and with hepatic insult or regeneration. Therefore, a tissue diagnosis is often required to guide subsequent management. The histology and anatomy of a pediatric liver tumor guides the treatment and prognosis.

Abstract
This article aims to give an overview of pediatric liver tumors; in particular of the two most frequently occurring groups of hepatoblastomas and hepatocellular carcinomas. Focus lays on achievements gained through worldwide collaboration. We present recent advances in insight, treatment results, and future questions to be asked. Increasing international collaboration between the four major Pediatric Liver Tumor Study Groups (SIOPEL/GPOH, COG, and JPLT) may serve as a paradigm to approach rare tumors. This international effort has been catalyzed by the Children's Hepatic tumor International Collaboration (CHIC) formation of a large collaborative database. Interrogation of this database has led to a new universal risk stratification system for hepatoblastoma using PRETEXT/POSTTEXT staging as a backbone. Pathologists in this international collaboration have established a new histopathological consensus classification for pediatric liver tumors. Concomitantly there have been advances in chemotherapy options, an increased role of liver transplantation for unresectable tumors, and a web portal system developed at www.siopel.org for international education, consultation, and collaboration. These achievements will be further tested and validated in the upcoming Paediatric Hepatic International Tumour Trial (PHITT).

Abstract
Infantile hemangiomas are the most common vascular tumors of infancy. A multidisciplinary approach including dermatologists, otolaryngologists, plastic surgeons, hematologists/oncologists and interventional/diagnostic radiologists is crucial for appropriate management of children with complicated infantile hemangiomas. Since its unforeseen discovery in 2008, propranolol has become the first-line treatment for infantile hemangiomas, eclipsing systemic corticosteroids and radiologic intervention. There are still, however, uncommon indications for more aggressive interventional management. We review the 2014-updated International Society for the Study of Vascular Anomalies (ISSVA) classification for vascular anomalies. Additionally, we suggest management algorithms for complicated lesions, including recommendations for radiologic and surgical intervention.

Abstract
Multifocal hepatic hemangioma (MHH) is a benign hepatic tumor that is commonly diagnosed in children with multiple cutaneous infantile hemangiomas (IHs). We present a review of all children with MHH at our institutions. Of the 42 patients, the median age at presentation of MHH was 2.5 months. Thirty-six (85.7%) patients had cutaneous IHs. Twelve (28.6%) patients were symptomatic at presentation. There was no significant association between the number of hepatic hemangiomas and the number of cutaneous IHs. Fourteen (33.3%) patients received some form of treatment for hepatic hemangiomas. The most common type of treatment was oral prednisone in 8 patients, followed by oral propranolol in 6 patients. Two patients were totally resistant to prednisone treatment. They died from congestive heart failure or respiratory distress and coagulopathy. Two patients with problematic facial IH were treated with intralesional triamcinolone injection. The remaining 26 patients were managed with imaging surveillance. On follow-up, all of the survivors had a favorable outcome. Our study suggests that the clinical features of MHH are variable. Our data emphasize the treatment strategy that aggressive treatment is indicated in symptomatic or progressive MHHs, whereas observation management of asymptomatic patients with a few small lesions is safe and appropriate.

Abstract
We aim to provide an up-to-date summary of infantile hepatic hemangioma (IHH) and its misnomers and to dialectically present the differential diagnosis of these rare entities of the liver. Eligible peer-reviewed articles on hepatic infantile hemangiomas, published between 2000 and 2015, were reviewed for this study. IHH is the most common hepatic vascular tumor in children. Once a liver mass is identified in an infant, the differential diagnosis ranges from vascular malformations to benign and malignant tumors including mesenchymal hamartoma, hepatoblastoma, metastatic neuroblastoma, so careful physical examination, imaging studies, and, if indicated, tumor markers and biopsy, are of pivotal importance to ascertain the correct diagnosis. Despite the benign nature of IHHs, some of these lesions may demand medical and/or surgical intervention, especially for multiple and diffuse IHH. Complications can include hepatomegaly, hypothyroidism and cardiac failure. Therefore, a close follow-up is required until complete involution of the lesions. We propose an algorithm to guide the physicians towards the proper management of hepatic lesions.

Abstract
In the pediatric patient, computed tomography (CT) scan as an imaging modality for evaluation of the abdomen is to be used judiciously. The use of correct scanning protocols, single phase scanning, scanning only when required are key factors to minimize radiation doses to the child, while providing diagnostic quality. CT is the preferred modality in the evaluation of trauma, to assess extent of solid organ or bowel injury. It is also useful in several inflammatory conditions such as inflammatory bowel diseases and acute pancreatitis. CT also has an important role in evaluating intra-abdominal tumors, although magnetic resonance imaging (MRI) can be used as an alternative to CT.

Abstract
Although primary hepatic neoplasms are less common than other intra-abdominal tumors in children, these neoplasms are a significant source of morbidity and mortality in the pediatric population. MRI is increasingly relied upon in the diagnostic evaluation of these lesions, both before and after treatment, and familiarity with the MRI findings associated with these neoplasms is a must for pediatric radiologists. Advances in MRI technology, particularly the advent of hepatocyte-specific gadolinium-based MRI contrast agents, have allowed for accurate characterization of several types of hepatic neoplasms on the basis of imaging appearance. In this review, we provide an overview of the approach to imaging hepatic neoplasms in children using MRI, including a sample imaging protocol. We also discuss the relevant clinical features and MRI findings of the most clinically relevant entities, including their appearance on post-contrast imaging using hepatocyte-specific gadolinium-based MRI contrast agents.

Abstract
BACKGROUND Congenital intrahepatic shunts in children are rare and precise treatment strategies have not been established. OBJECTIVE The purpose of this study was to present our experience with transcatheter embolization in a descriptive case series of congenital intrahepatic shunts in children. MATERIALS AND METHODS We retrospectively studied 10 children with symptomatic congenital intrahepatic shunts who were treated with embolization at our institute between January 2008 and December 2014. RESULTS Seven children had arteriovenous shunts in association with hepatic hemangiomas, two had arterioportal shunts and one had portosystemic shunts. The major presentations were congestive heart failure and severe anemia in the groups with arteriovenous and arterioportal shunts, respectively. Following embolization, two children died in the arteriovenous group, one from progressive liver dysfunction and the other from abdominal compartment syndrome. One child in the arterioportal group required liver transplantation after initial embolization. With mean post-procedure follow-up of 15 months (range 4-54 months), all the remaining children were well, with resolution of the symptoms. CONCLUSION Interventional embolization provides an alternative to surgical ligation or hepatic resection in children with clinically significant intrahepatic shunts. For lesions with complex morphology, embolization may be inadequate and liver transplantation might be the only therapeutic option.

Abstract
Infantile hepatic hemangioendothelioma (IHH) is the most common vascular tumor of the liver in infancy. Adult with IHH is extremely rare. We presented a diffuse IHH in an adult patient with computed tomography (CT) and magnetic resonance image (MRI) findings.A 39-year-old man was admitted to our hospital because of a 2-year history of abnormal liver function tests and a 7-day history of jaundice. Physical examination revealed enlarged liver. Unenhanced abdominal CT showed enlargement of the liver with diffuse hypodensity. Enhanced CT on the arterial phase revealed multiple centrally enhanced lesions diffusely involved the enlarged liver. The enhanced areas of the lesions became larger on the portal phase and all the lesions became homogeneous enhanced on the delayed phase. These lesions showed heterogeneously hyperintense on T2-weighted image, hypointense on T1-weighted image, and early centrally enhanced on dynamic gadolinium-enhanced MRI, with complete tumor enhancement after 180 s. The patient underwent orthotopic liver transplantation. IHH type 2 was confirmed by pathology. The patient died of tumor recurrence in the liver 4 months after transplantation.Unlike the previously described imaging appearances of IHH, this case showed diffuse nodules with early central enhancement on CT and MRI. Considering the importance of the ability to differentiate IHH from other hepatic tumors, radiologists should be aware of these imaging appearances to establish knowledge of the entire spectrum of IHH.

Abstract
Infantile hepatic hemangioendothelioma (IHH) is rare which can regress spontaneously. Arteriovenous shunts within hemangiomas, however, may result in pulmonary artery hypertension (PAH) and congestive heart failure (CHF).The authors report 2 young infants suffering from multifocal IHH associated with CHF were both treated with glucocorticoid and transcatheter arterial embolization (TAE), but had different outcomes. The PAH decreased immediately and the symptoms of CHF were alleviated after TAE for both of them. For the Tibetan infant, the development was normal with tumor regression by follow-up. For the Han ethnic neonate, PAH increased again in the seventh day with progressive cardiovascular insufficiency. Ultrasound showed a persisting perfusion caused by collateralization around occluded main feeders. Furthermore, a pulmonary infection occurred and ventilation was performed. As a result, the infant died from multiorgan failure caused by CHF and infection.TAE is a treatment of reducing shunting for hemangiomas. Fistula recanalization in multifocal IHH, however, might be an important risk factor affecting the outcome of TAE. TAE should be further evaluated with special attention to anatomy of feeding and draining vessels, and cardiopulmonary conditions. In addition, the patients were susceptible to secondary pulmonary infection because of lung congestion. As well, the infant from the high altitude area showed better adaptability to hypoxia.

Abstract
PURPOSE Benign liver tumors in children are rare and data regarding the surgical outcomes are deficient. We reviewed our experience in the management of these tumors particularly the extent, safety, and effectiveness of surgical resection. METHODS Between March 2005 and March 2014, 10/90 liver resections were performed for benign liver tumors. Three other patients received conservative treatment. Demographic characteristics, operative management, morbidity, and mortality were analyzed. RESULTS The median age of the patients was 12 months. The distribution of pathology was infantile hepatic hemangioendothelioma/hemangioma (n = 7), mesenchymal hamartoma (n = 4), adenoma (n = 1) and focal nodular hyperplasia (n = 1). Median tumor size was 12.25 cm (range 3.5-21 cm) with a median tumor volume of 576.64 cm(3) (range 13.9-1822.64 cm(3)). Non-anatomic resection was performed in 6/10 patients and the median blood loss was 100 ml (range 10-850 ml). Median length of hospital stay was 7 days (range 5-9 days). There were no mortality, none of the patients had a local recurrence, and all are alive at a median follow-up of 33 months. CONCLUSIONS Two-third patients with benign liver tumors were managed with surgical excision, which comprised 11% of our resectional practice. Non-anatomical resection whenever feasible can be performed safely and does not compromise the oncological outcomes.

Abstract
OBJECTIVES Hepatic hemangiomas are often found in association with multiple cutaneous infantile hemangiomas. Screening abdominal ultrasonography has been recommended for patients with five or more cutaneous lesions. We sought to determine whether hemangiomas found through screening had improved clinical outcomes. METHODS Patients entered into our hepatic hemangioma registry between 1995 and 2012 were reviewed. RESULTS Seventy-two patients with multiple cutaneous and hepatic hemangiomas were identified; 43 (60%) were detected through screening. The median age at diagnosis was 41 days for screened patients and 53 days for those not screened. Screening detected 40 (93%) multifocal and 3 (7%) diffuse hemangiomas, compared to 18 (62%) and 11 (38%), respectively, in the nonscreened group. Patients identified by screening had lower incidences of congestive heart failure and hypothyroidism and were less likely to receive treatment for their hemangiomas. The mortality rate in the children not screened was 28% (n = 8). None of the patients found by screening died (p < 0.001). Multivariate analysis of treated patients demonstrated that screening was a significant predictor of reduced mortality (p = 0.04). CONCLUSION Hepatic hemangiomas found through screening ultrasonography are less likely to develop serious clinical sequelae. Although the reasons for this may include detection of hemangiomas that are less likely to progress to symptomatic disease, it appears that it also allows for earlier intervention for more concerning (e.g. diffuse) subtypes. Screening may allow for closer surveillance and earlier treatment before life-threatening progression in a subset of infants with liver hemangiomas, preventing complications and reducing mortality.

Abstract
Infantile hemangiomas (IHs) are the most common tumors of childhood. Unlike other tumors, they have the unique ability to involute after proliferation, often leading primary care providers to assume they will resolve without intervention or consequence. Unfortunately, a subset of IHs rapidly develop complications, resulting in pain, functional impairment, or permanent disfigurement. As a result, the primary clinician has the task of determining which lesions require early consultation with a specialist. Although several recent reviews have been published, this clinical report is the first based on input from individuals representing the many specialties involved in the treatment of IH. Its purpose is to update the pediatric community regarding recent discoveries in IH pathogenesis, treatment, and clinical associations and to provide a basis for clinical decision-making in the management of IH.

Abstract
Abstract
We report a case of uncomplicated giant fetal hepatic hemangioma with a good outcome. A 57×38 mm heterogeneous hepatic mass, mostly hypoechogenic was observed post prenatal ultrasound, at 33 weeks’ gestation (WG) and 5 days. Color Doppler confirmed the vascular pattern of the mass. The image size stayed stable, with no associated complications, and a cesarean birth at 37 WG was performed for fetal protection. Subsequent postnatal follow-up showed spontaneous regression of the tumor. Antenatal diagnosis and management of fetal liver masses are discussed in this paper. This case supports the hypothesis that complications of giant fetal hepatic hemangioma are not related only to its size. Prognostic factors and guidelines for follow-up need to be determined.

Abstract
Objective: The purpose of this study is to present our experience with MRI evaluation of multifocal liver lesions in children and describe the MRI characteristics of these lesions. Patients and Methods: A retrospective review of consecutive MRI exams performed for the evaluation of multiple liver lesions between 1 January 2007 and 31 December 2012 was done to note the number of lesions, the size of the largest lesion, MR signal characteristics, and background liver. Final diagnosis was assigned to each case based on pathology in the available cases and a combination of clinical features, imaging features, and follow-up in the remaining cases. Results: A total of 48 children (22 boys, 26 girls; age between 3 months and 18 years with average age 10.58 years and median age 11 years) were included in the study. Totally 51 lesion diagnoses were seen in 48 children that included 17 focal nodular hyperplasia (FNH), 8 hemangiomas, 7 metastases, 6 regenerative nodules, 3 adenomas, 3 abscesses, and one each of angiomyolipoma, epithelioid hemangioendothelioma, focal fatty infiltration, hepatocellular carcinoma, hepatic infarction, nodular regenerative hyperplasia, and hepatic cyst. Background liver was normal in 33, cirrhotic in 10, fatty in 3, and siderotic in 2 children. Most FNH, hemangiomas, and regenerative nodules showed characteristic MRI features, while metastases were variable in signal pattern. Conclusion: Many commonly seen multifocal liver lesions in children have characteristic MRI features. MRI can help to arrive at reasonable differential diagnoses for multifocal liver lesions in children and guide further investigation and management.
