Abstract
Non-cirrhotic portal hypertension (NCPH) is a well-recognized clinico-pathological entity, which is associated with clinical signs and symptoms, imaging, and endoscopic features of portal hypertension (PHT), in absence of cirrhosis. In patients with NCPH without known risk factors of PHT or extrahepatic portal vein thrombosis, the condition is called idiopathic non-cirrhotic portal hypertension (INCPH). There are multiple infectious, immune related causes, systemic diseases, drug and toxin exposures, haematological disorders, and metabolic risk factors that have been associated with this INCPH. However, the causal pathogenesis is still unclear. The Vascular liver disorders interest group group recently proposed porto-sinusoidal vascular disease (PSVD) as a syndromic entity, which provides definite histopathological criteria for diagnosis of NCPH (table 1). The three classical histo-morphological lesions specific for PSVD include obliterative portal venopathy, nodular regenerative hyperplasia, and incomplete septal fibrosis. The PSVD definition includes patients with portal vein thrombosis, PVT, and even those without PHT, thus broadening the scope of diagnosis to include patients who may have presented early, prior to haemodynamic changes consistent with PHT. However, this new diagnosis has pros and cons. The cons include mandating invasive liver biopsy to assess the PSVD histological triad in all patients with NCPH, an erstwhile clinical diagnosis in Asian patients. In addition, the natural history of the subclinical forms of PSVD without PHT and linear progression to develop PHT is unknown yet. In this review, we discuss the diagnosis and treatment of INCPH/PSVD, fallacies and strengths of the old and new schema, pathobiology of this disease, and clinical correlates in an Asian context. Although formulation of standardised diagnostic criteria is useful for comparison of clinical cohorts with INCPH/PSVD, prospective clinical validation in global cohorts is necessary to avoid misclassification of vascular disorders of the liver.

Abstract
Biliary atresia is challenging to diagnose because many of the clinical and imaging features of this condition overlap with those of other causes of cholestasis in newborns. When jaundice persists beyond 2 weeks of age, the neonate should be evaluated for cholestasis, and biliary atresia - the most common cause of neonatal cholestasis - should be considered. It is critical to diagnose biliary atresia early because failure to treat can result in hepatic fibrosis and death in less than 1 year. In this paper, we review the current diagnostic imaging methods, differential considerations and treatment options for biliary atresia.

Abstract
Johanson-Blizzard Syndrome (JBS) is a rare autosomal recessive genetic disorder characterized by exocrine pancreatic insufficiency, distinct abnormal facial appearance and varying degrees of growth retardation. Variants in UBR1 gene are considered to be responsible for the syndrome. Here, we describe a 3-year old boy, who visited our clinic for severe growth retardation and frequent oily diarrhea. The physical examination revealed nasal alae aplasia, scalp defect, and maldescent of left testicle. Transabdominal ultrasound and computed tomography scan of his abdomen demonstrated complete fatty replacement of the pancreas. The clinical, laboratory, and imaging findings strongly suggest the diagnosis of hereditary pancreatitis. Whole exome sequencing revealed two rare compound heterozygous variants, c.2511T > G (p.H837Q) and c.1188T > G (p.Y396X), in the UBR1 gene of this boy, so, the diagnosis of JBS was established. This is the first report of Chinese patient with JBS, and our study indicates that transabdominal ultrasound and computed tomography are two useful and noninvasive imaging methods for the diagnosis and evaluation of JBS, and identification of these two novel variants expands the database of UBR1 gene variants. Furthermore, with the availability of the identification technology for these variants, prenatal diagnosis could be offered for future pregnancies.

A rare case of accessory spleen torsion in a child diagnosed by ultrasound (US) and contrast-enhanced ultrasound (CEUS). J Ultrasound 2019; 22:99-102. [PMID: 30758809 DOI: 10.1007/s40477-019-00359-4] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2018] [Accepted: 01/11/2019] [Indexed: 12/12/2022] Open
Abstract
INTRODUCTION Accessory spleen, also known as supernumerary spleen or splenunculum, is a congenital anomaly of the spleen due to a fusion defect during the embryogenesis. Usually it is detected casually during an ultrasound (US) examination of the abdomen and it is asymptomatic. CASE REPORT RESULTS: We present a case of a 12 years old male patient, with 2-days history of left abdominal pain, without fever, gastrointestinal or genitourinary symptoms. The day before our observation, the patient had gone to another hospital, from where he had been discharged with medical analgesic therapy, without any benefit. Blood tests were normal, the Ultrasound abdominal examination showed normal aspect of abdominal organs, but the presence in the left side of a small round parenchymal structure surrounded by hyperechogenic mesenteric fat. We interpreted this image as an accessory spleen, complicated by torsion. As the torsion of accessory spleen is a quite rare occurrence, we carried out a contrast enhanced ultrasound (CEUS) to get more information. CEUS showed the absence of enhancement of the nodular formation, suggestive for a complete lack of vascularization; the spleen was normally enhanced. While the management in case of accessory spleen torsion is non-operative, in this case the patient underwent surgical exploration, due to the persistence of abdominal pain despite the medical therapy, with clinical signs of peritoneal reaction, mimicking an acute abdomen. Surgery confirmed the diagnosis of accessory spleen torsion. DISCUSSION AND CONCLUSIONS In conclusion, US is the first diagnostic tool in pediatric abdominal pain and allows to direct the diagnosis; the use of CEUS helps to clarify the US reports, without leaving doubts about the parenchymal vascularization of the abdominal organ involved.

Abstract
The pancreas is easily investigated in children thanks to the relative lack of fat tissue and the large left hepatic lobe with an optimal acoustic window. The use of high frequency, even linear transducers, usually results in detailed images of all pancreatic areas. A wide spectrum of pancreatic pathologic conditions can be identified and monitored at ultrasound although they are relatively uncommon during childhood compared to the adult. In this paper we briefly review the anatomy, technique, and sonographic aspects of normal and pathological pediatric pancreas.

Abstract
In infants and children, the spleen is involved in many pathological processes, whether those processes are isolated or related to systemic diseases. Pathology of the pediatric spleen includes congenital anomalies, splenomegaly, trauma, focal lesions, infarction, and tumors. Ultrasonography (US) is a widely available, fast, noninvasive imaging technique to assess the size, shape, and position of the spleen, as well as to define splenic echotexture. US is capable of screening for splenic disorders without the risk of ionizing radiation; it is the initial imaging examination performed to evaluate suspected splenic pathology, providing clinicians with helpful decisional support. US plays an important role in the detection of even very small amounts of hemoperitoneum, a herald of significant abdominal organ injury, in pediatric blunt abdominal trauma. Moreover, contrast-enhanced US may allow early detection of splenic injuries, ideally minimizing children's risk from radiation exposure. This pictorial essay illustrates the normal ultrasound appearance of the pediatric spleen and the sonographic findings which may guide clinicians to a correct diagnosis of pathologic conditions.

Abstract
Congenital aberrant hepatic vascular communications result from intrahepatic or extrahepatic errors in vascular development or involution during the transition from fetal to newborn hepatic circulation. These hepatic vascular shunts can be fortuitously discovered and asymptomatic, or can cause symptoms of varying severity, often presenting diagnostic dilemmas. Some hepatic vascular shunts resolve spontaneously while others require interventional radiologic or surgical closure. Affected patients are often first studied with real-time and Doppler ultrasound, so radiologists should familiarize themselves with the expected ultrasound findings of these vascular shunts for effective diagnosis, triage and management. In this review, the authors focus on ultrasound and Doppler findings of hepatic vascular shunts with underlying embryology, clinical features and management strategies. Broadly, these aberrant hepatic vascular communications include portosystemic venous shunts (which can be intra- or extrahepatic and include persistent patent ductus venosus), arterioportal, arteriovenous or mixed shunts.

Abstract
Congenital portosystemic shunts (CPSS) are rare vascular malformations that create an abnormal connection between portal and systemic veins resulting in complete or partial diversion of the portal flow away from the liver to the systemic venous system. Different anatomic types exist and several classifications have been proposed. They can be associated with other malformations especially cardiac and heterotaxia. The main complications include hepatic encephalopathy, liver tumors, portopulmonary hypertension, and pulmonary arteriovenous shunts. Diagnosis relies on imaging, and prenatal diagnosis is possible. Spontaneous closure of the CPSS is possible in some anatomic forms during the first year of life. When the CPSS remains patent, radiologic or surgical closure of the CPSS may prevent, resolve, or stabilize complications. Interventional radiology plays a key role for both the preoperative evaluation with occlusion test to assess the exact anatomy and to measure portal pressure after occlusion of the CPSS. Endovascular closure is the first option for treatment when possible.
