UNASSIGNED: Caroli syndrome or Caroli disease is characterized by focal dilation of the intrahepatic bile ducts, with or without congenital liver fibrosis. Mutations in the WDR19 gene can result in nephropathy, an autosomal recessive cystic kidney disease. However, this genetic mutation is clinically associated with Caroli syndrome or disease. We hypothesize that WDR19 gene mutations may contribute to extrarenal phenotypes such as Caroli disease or syndrome.
UNASSIGNED: The outpatient department received a 1-year-old male patient with persistent dilated bile ducts for over four months. Subsequent ultrasound examination revealed liver cirrhosis, splenomegaly, and cystic dilatation of the intrahepatic bile duct. He was subsequently admitted for comprehensive diagnosis and treatment. Accordingly, we performed computed tomography (CT)-hepatic portal venography, magnetic resonance-cholangiography, and the plain liver scan, the results revealed liver cirrhosis, splenomegaly, cystic dilatation of the intrahepatic bile duct, as well as atypical hyperplasia nodules in the right posterior lobe of the liver and lymphatic hyperplasia and enlargement in the porta hepatis and the space between the liver and stomach. As the possibility of early small liver cancer could not be excluded due to the presence of nodules, surgical resection was performed followed by pathological examination and whole genome exome testing. The pathological findings revealed hepatocyte swelling, hydropic degeneration, and sporadic necrosis. Fibrous tissue hyperplasia was observed in the portal vein area, along with local pseudolobule formation. Also, numerous small bile duct hyperplasia was observed with lymphocyte infiltration, which is consistent with cirrhosis. Moreover, the hepatocytes of the small focal area showed atypical hyperplasia. Considering the above findings, Caroli syndrome was diagnosed. The genetic results showed two heterozygous mutations in the WDR19 gene, c.2290delC (p.Q764Nfs*29) and c.2401G>C (p.G801R). Therefore, the child\'s intrahepatic bile duct dilatation and cirrhosis were considered as the manifestations of Caroli syndrome caused by mutations in the WDR19 gene.
UNASSIGNED: Mutations in the WDR19 gene can manifest as Caroli disease or Caroli syndrome. For the definite diagnosis of liver diseases of unknown etiology, whole exome sequencing may be more conducive.

Caroli\'s disease is also known as Congenital intrahepatic bile duct dilatation, and previously known as a congenital intrahepatic bile duct cyst; it is characterized by single or multiple intrahepatic cystic dilatations. In this article, we report a case of Caroli\'s disease (CT size 21.2 × 16.9 × 19.8 cm). Preoperative abdominal ultrasound and enhanced CT were misdiagnosed as biliary cystadenoma or hepatic echinococcosis, and finally diagnosed as Caroli\'s disease by postoperative histopathological examinations. Most of the disease is single or multiple cystic dilatation of small bile duct. Giant Caroli disease, cystic dilations with diameter >20 cm is very rarely seen in the clinic. The lack of experience of diagnosing giant cystic dilatation makes it difficult to make accurate diagnosis. Therefore, we analyze the causes of imaging misdiagnosis through this case report, and summarize the imaging diagnostic skills of the disease combined with relevant imaging diagnosis experience. The purpose of this study is to deepen the understanding of giant Caroli disease among imaging doctors so as to reduce the misdiagnosis of the disease in the future.

Caroli\'s syndrome is a congenital disease characterized by dilation of intrahepatic bile ducts and congenital hepatic fibrosis. It is a rare condition in clinical work. Typically, the diagnosis of this disease is confirmed through medical imaging. Here, we report a case of atypical Caroli\'s syndrome in a patient who presented with recurrent upper gastrointestinal tract bleeding. The patient underwent imaging examinations, liver biopsy and whole exome sequencing. The results of the imaging examination were non-specific. However, with the aid of pathological examination, the patient was diagnosed with Caroli\'s syndrome. In conclusion, for cases where the imaging presentation of Caroli\'s syndrome is inconclusive, an accurate diagnosis should rely on pathology. By discussing this specific case, our aim is to enhance readers\' understanding of this disease, provide valuable information that can aid in the early detection and appropriate management of Caroli\'s syndrome, ultimately improving patient outcomes.

BACKGROUND If a young patient presents with fever, abdominal pain, jaundice and significant imaging abnormalities, especially dilation of the biliary system, it is usually due to obstruction from stones or strictures. However, on very rare occasions, it can be due to complications of congenital cystic dilatation of the biliary system, known as Caroli disease. We present such a patient and discuss the differential diagnosis and implications for long-term management. CASE REPORT A 14-year-old boy presented to the Emergency Department with a sudden onset of high-grade fever and abdominal pain for 2 weeks, accompanied by vomiting of blood. The patient had no relevant medical history. He was malnourished and had moderate pallor, jaundice, and right upper quadrant pain. Imaging revealed cystic dilatation of intrahepatic ducts and a central dot sign. There were no features suggesting advanced liver disease otherwise, and no tumors or cysts in the kidneys. A diagnosis of Caroli disease was made. The symptoms were ascribed to acute cholangitis and improved with antibiotics. He was discharged home 1 week later. No further blood loss was observed. CONCLUSIONS This case study describes a patient with ascending cholangitis, a complication of Caroli disease. This diagnosis should be considered in the differential diagnosis when a child or young adult presents with features of cholangitis, abnormal biliary imaging, and/or upper gastrointestinal bleeding, or portal hypertension. No prior cases of this disease have been encountered, documented, or published in Kenya. This case can increase awareness among primary care clinicians, including pediatricians.

Caroli disease is a rare congenital malformation that predisposes to segmental cystic dilatation of the intrahepatic bile ducts. Banti syndrome is characterized by persistent splenomegaly due to chronic congestion, resulting in a low hematocrit and ultimately leading to pancytopenia. In this report, we describe a 29-year-old woman who presented with a >20-year history of hepatitis B surface antigen positivity and a >1-year history of recurrent fatigue and malaise. On examination, the patient had abdominal distension with marked splenomegaly (7 cm below the ribs) and ascites with tenderness of the abdominal muscles to palpation. A complete blood count showed a low white blood cell count, red blood cell count, and hemoglobin concentration. During the course of treatment, the patient developed multiple symptoms of pancytopenia and concomitant splenomegaly, and she was discharged after total splenectomy with good recovery. The combination of Banti syndrome and Caroli disease results in severe symptoms of portal hypertension.

BACKGROUND: The disease of Caroli is a rare congenital disorder, characterized by the dilated intrahepatic bile ducts, resulting from mutations in the PKHD1 gene. Caroli syndrome, characterized by dilated intrahepatic bile ducts with congenital hepatic fibrosis, is linked to autosomal recessive polycystic kidney disease. The clinical manifestations of Caroli disease are not typical, and Caroli disease is easy to be missed and misdiagnosed. Therefore, we reported this case in the hope of raising awareness of the disease among clinicians.
METHODS: The clinical manifestation of a 10-year-old girl was subcutaneous hemorrhage.
METHODS: Magnetic resonance imaging (MRI ) indicates that the person may have Caroli disease, cirrhosis, splenomegaly, portal hypertension, esophagogastric fundal varices, or sponge kidneys.
METHODS: The patient was advised for liver transplantation.
RESULTS: The patient parents did not take our treatment advice, and they asked to go to a better hospital for further treatment, so we did not give the patient any treatment.
CONCLUSIONS: This case serves as a reminder that if we encounter a patient with hemophilia in our clinic, we should not only consider hematologic diseases and cirrhosis, but also perform an epigastric MRI and magnetic resonance cholangiopancreatography to rule out Caroli disease.

Autosomal recessive polycystic kidney disease (ARPKD) is the rare and usually early-onset form of polycystic kidney disease with a typical clinical presentation of enlarged cystic kidneys and liver involvement with congenital hepatic fibrosis or Caroli syndrome. ARPKD remains a clinical challenge in pediatrics, frequently requiring continuous and long-term multidisciplinary treatment. In this review, we aim to give an overview over clinical aspects of ARPKD and recent developments in our understanding of disease progression, risk patterns, and treatment of ARPKD.

A patient with Caroli disease is described. The authors used 3D modeling and 3D printing when choosing surgical strategy. Advisability of 1.5% meglumine sodium succinate 500 ml IV once a day (courses for 5 and 8 days) is justified. Thanks to antihypoxic mechanism, this drug reduced intoxication syndrome and length of hospital-stay, as well as improved quality of life.
Описано клиническое наблюдение болезни Кароли. Приведен пример использования 3D-моделирования и 3D-печати при выборе хирургической тактики. Обосновано включение в схему терапии сопровождения 1,5% раствора меглюмина натрия сукцината (внутривенно капельно 1 раз в день 500 мл, курсы 5 и 8 дней), который благодаря своему антигипоксическому механизму действия способствовал уменьшению интоксикационного синдрома и, как следствие, сокращению сроков госпитализации и повышению качества жизни пациентки.
