Caroli's disease incidentally discovered in a 16-years-old female: a case report.

Caroli´s disease is a congenital hepatic disorder characterized by nonobstructive saccular or fusiform dilatation of the intrahepatic bile ducts with the absence of congenital hepatic fibrosis. Caroli´s disease is rare, with few reported cases in the literature, making it hard to distinguish from other liver abnormalities. We present a case of Caroli´s disease discovered indecently in a 16-year-old female who presented with recurrent abdominal pain and intermittent jaundice in the last three years. Abdominal Computed tomography (CT) showed mild liver enlargement with multiple cystic dilatations of the intrahepatic saccular bile ducts cystic dilatations without hepatic fibrosis. The patient was treated conservatively with ursodeoxycholic acid and antibiotic therapy and discharged with regular follow-up. In conclusion, Caroli´s disease should be considered in the differential diagnosis in patients with recurrent abdominal pain and cholangitis without risk factors or relevant history.

Haemostatic radiation therapy for a bleeding intraductal papillary neoplasm of the biliary tree.

Haemostatic radiation was effectively used as a novel rescue therapy in a 60-year-old man who presented with recurrent melaena refractory to all conventional medical and surgical measures. He needed multiple transfusions and was diagnosed to be bleeding from an intraductal papillary biliary neoplasm which was not amenable to surgical resection in view of the background liver disease. He received conventional radiation therapy (RT) of a dose of 3 Gy per fraction for 3 consecutive days after which he stabilised. After cessation of the RT, he did not require transfusion for the next 2 months. His quality of life improved and it gave us time to evaluate for other definitive measures.

Recurrent Cholangitis in a Patient with Autosomal Dominant Polycystic Kidney Disease (ADPKD) and Caroli's Disease.

We herein present a rare case of an autosomal dominant polycystic kidney disease (ADPKD) patient with Caroli's disease, a congenital embryonic biliary tree ductal plate abnormality often associated with autosomal recessive polycystic kidney disease. A 76-year-old woman with ADPKD on hemodialysis was admitted to our hospital with recurrent cholangitis and hepatobiliary stones. Caroli's disease was diagnosed according to typical imaging findings of cystic intrahepatic bile duct dilatation and the central dot sign. Hepatobiliary system abnormalities such as Caroli's disease should be considered in febrile ADPKD patients, even in the absence of typical clinical signs or symptoms.

Clinical classification of Caroli's disease: an analysis of 30 patients.

BACKGROUND: Caroli's disease (CD) is a rare congenital disorder. The early diagnosis of the disease and differentiation of types I and II are of extreme importance to patient survival. This study was designed to review and discuss observations in 30 patients with CD and to clarify the clinical characteristics of the disease. METHODS: The demographic and clinical features, laboratory indicators, imaging findings and pathology results for 30 patients with CD were reviewed retrospectively. RESULTS: Caroli's disease can occur at any age. The average age of onset in the study cohort was 24 years. Patients who presented with symptoms before the age of 40 years were more likely to develop type II CD. Approximately one-third of patients presented without positive signs at original diagnosis and most of these patients were found to have type I CD on pathology. Anaemia, leucopoenia and thrombocytopoenia were more frequent in patients with type II than type I CD. Magnetic resonance cholangiopancreatography (MRCP) and computed tomography (CT) examinations were most useful in diagnosing CD. CONCLUSIONS: No typical symptoms, signs or laboratory indicators are able to distinguish CD from other conditions. Both MRCP and CT were most valuable in diagnosis. The two types of CD may be differentiated by age of onset and routine blood tests.

Caroli's syndrome with autosomal recessive polycystic kidney disease.

Caroli's syndrome (CS) is a rare congenital disorder characterized by multiple segmental cystic or saccular dilatations of the intrahepatic bile ducts and congenital hepatic fibrosis. We report a 9-year-old boy who was diagnosed with CS and autosomal recessive poly-cystic kidney disease. On screening, his 5-month-old asymptomatic sister had multiple dilated biliary radicals with multiple bilateral renal cystic lesions. Both the patient and the affected sibling have been advised regular follow-up for monitoring the progression of the disease. In conclusion, patients with CS should be screened for renal cystic lesions and vice versa even if they are asymptomatic. Also, as the disease is inherited in an autosomal recessive manner, it is important to screen family members for early diagnosis and management.

Management of adults with paediatric-onset chronic liver disease: strategic issues for transition care.

Advances in the management of children with chronic liver disease have enabled many to survive into adulthood with or without their native livers, so that the most common of these conditions are becoming increasingly common in adult hepatology practice. Because the aetiologies of chronic liver disease in children may vary significantly from those in adulthood, adults with paediatric-onset chronic liver disease may often present with clinical manifestations unfamiliar to their adulthood physician. Transition of medical care to adult practice requires that the adulthood medical staff (primary physicians and subspecialists) have a comprehensive knowledge of childhood liver disease and their implications, and of the differences in caring for these patients. Pending still unavailable Scientific Society guidelines, this article examines causes, presentation modes, evaluation, management, and complications of the main paediatric-onset chronic liver diseases, and discusses key issues to aid in planning a program of transition from paediatric to adult patients.

Rare cystic liver lesions: a diagnostic and managing challenge.

Cystic formations within the liver are a frequent finding among populations. Besides the common cystic lesions, like simple liver cysts, rare cystic liver lesions like cystadenocarcinoma should also be considered in the differential diagnosis. Thorough knowledge of each entity's nature and course are key elements to successful treatment. Detailed search in PubMed, Cochrane Database, and international published literature regarding rare cystic liver lesions was carried out. In our research are included not only primary rare lesions like cystadenoma, hydatid cyst, and polycystic liver disease, but also secondary ones like metastasis from gastrointestinal stromal tumors lesions. Up-to date knowledge regarding diagnosis and management of rare cystic liver lesions is provided. A diagnostic and therapeutic algorithm is also proposed. The need for a multidisciplinary approach by a team including radiologists and surgeons familiar with liver cystic entities, diagnostic tools, and treatment modalities is stressed. Patients with cystic liver lesions must be carefully evaluated by a multidisciplinary team, in order to receive the most appropriate treatment, since many cystic liver lesions have a malignant potential and evolution.

Abernethy malformation with multiple aneurysms: incidentally found in an adult woman with Caroli's disease.

Abernethy malformation is a rare anomaly with partial or complete congenital absence of the portal vein and subsequent development of extrahepatic portocaval shunts. We present the case of a 28-year-old woman who was incidentally diagnosed with type II Abernethy malformation and multiple aneurysms during an investigation for nonspecific abdominal pain and fever. The patient had been diagnosed with Caroli's disease at the age of 10 and liver cirrhosis, portal hypertension a few years before. To the best of our knowledge, this is the first case reported with all such congenital anomalies associated together. Ultrasound, computed tomography, including three-dimensional reconstruction, and magnetic resonance imaging were performed which revealed a side-to-side shunt between the extrahepatic portal vein and the inferior vena cava, multiple aneurismal cystic dilation of the spleen artery and left renal artery, and extensive intrahepatic bile duct cysitic dilation with calculus formation. Etiology, clinical significance and management strategies with regard to these abnormalities are discussed.

Fibropolycystic disease of the liver and kidney in Oman.

BACKGROUND AND STUDY AIMS: Fibropolycystic disease of liver and kidney (FPCDLK) is an uncommon group of conditions inherited in an autosomal fashion. The group encompasses autosomal dominant polycystic disease of the kidney (ADPDK), autosomal recessive polycystic disease of the kidney (ARPDK), congenital hepatic fibrosis (CHF) and Caroli's disease (CD). There are limited data of this disease in the world. We report our experience in the Royal Hospital (RH) in Oman and data regarding long-term follow-up. The aim of the study was to document the frequency of encounter, clinical presentation and outcome of FPCDLK in Division of Child Health in RH, Muscat. PATIENTS AND METHODS: Charts of patients diagnosed with ARPDK, ADPDK, CHF and CD were reviewed from the period of 16 February 2006 till 31 December 2011. Parameters including anthropometry, liver function tests, renal function tests, presence of oesophageal varices, hypersplenism, renal or liver transplantation and performance of porto-systemic shunt surgeries were all investigated. RESULTS: A total of 33 patients were identified, including 19 males and 14 females. The frequency of encounter of FPCDLK in RH was 1.5/1,000,000 population. The mean age of patients was 7.4years. The mean age at diagnosis was 27months. The mean duration of follow-up was 5.5years. A total of 31% of patients had an incidental finding of hepatomegaly, and 25% were detected by antenatal screening. Three children presented with renal failure, and 13 children in total had renal function abnormalities by the end of the study period. One child presented with haematemesis at the age of 1year. Two children underwent renal transplant and one child required splenectomy with a splenorenal shunt. A total of 54% had endoscopic variceal screen and two required banding on first endoscopy. The demise of one patient was observed during the study. CONCLUSION: FPCDLK is uncommon in Oman but carries major mortality and morbidity for the patient and family. The gene is present in the Gulf countries. Management is mainly through portal hypertension and renal supportive care until definitive dual organ transplant. This disease needs to be further investigated in the Arab world.

Caroli's syndrome in a post renal transplant patient: case report and review of the literature.

Caroli's syndrome is characterized by bile duct ectasia in association with hepatic fibrosis. It is usually transmitted in an autosomal recessive fashion and has been well documented to be associated with autosomal recessive polycystic kidney disease and occasionally with autosomal dominant polycystic kidney disease. However, there has been only few case reports published with Caroli's syndrome diagnosed postrenal transplantation.

[Caroli's syndrome in a patient on hemodialysis: diagnostic and therapeutic difficulties]. / Sindrome di Caroli in paziente emodializzato: difficoltà diagnostiche e terapeutiche.

We present the case of a 65-year-old male patient without any family history of renal or hepatic disease. He had been on maintenance hemodialysis for 4 months because of autosomal recessive polycystic kidney disease. At the start of the hemodialysis session he reported general malaise, abdominal pain, fever and diarrhea occurring in the last two days. Laboratory workup showed neutrophilic leukocytosis and increased serum amylase and C-reactive protein. Abdominal contrast-enhanced CT scan and MRI cholangiography showed hepatic cysts with marked dilatation of the intra- and extrahepatic bile ducts. The patient underwent cholecystectomy with hepaticojejunal Rouxen- Y anastomosis and was discharged with oral ciprofloxacin. Histology confirmed marked cystic dilatation of the bile ducts. Because of persistent episodes of septic fever, administration of ciprofloxacin was continued. After 4 months retrograde endoscopic pancreatography was performed which led to a diagnosis of Caroli's syndrome associated with polycystic kidneys. Given the rarity of the disease and its difficult diagnosis, when patients with polycystic kidneys and liver cysts experience recurrent episodes of septic fever of unknown origin, Caroli's disease should be taken into account and the appropriate tests should be carried out to confirm the diagnosis.

Síndrome de Caroli: relato de caso clínico / Caroli´s syndrome: clinical case report

Objetivo: apresentar caso clínico de paciente internada em um hospital em Belém do Pará, no qual foi diagnosticado Síndrome de Caroli e sua evolução após terapêutica adequada. Relato do Caso: paciente do sexo feminino, 37 anos, com quadro de hemorragia digestiva alta volumosa, internada de urgência em hospital de grande porte. Ao exame apresentava-se desidratada, descorada, com distensão abdominal e hepatoesplenomegalia. À endoscopia digestiva detectaram-se varizes esofagianas com sangramento ativo, as quais foram submetidas à escleroterapia. A investigação hospitalar posterior constatou hepatopatia crônica e dilatações saculares das vias biliares intra-hepáticas, com fibrose hepática difusa, consolidando-se o diagnóstico de Síndrome de Caroli. A paciente atualmente está em seguimento ambulatórial, aguardando realização de transplante hepático. Considerações finais: o caso de Síndrome de Caroli estudado ratifica a importância da doença como diagnóstico diferencial em pacientes que apresentam quadro clínico compatível com síndrome de hipertensão portal e colangite, com necessidade de diagnóstico precoce devido ao risco caracteristicamente aumentado de colangiocarcinoma, sendo muitas vezes o transplante hepático a melhor opção terapêutica.

Objective: to report the clinical case of a patient admitted to a hospital in Belem, which was diagnosed Caroli's syndrome, and her evolution after appropriate therapy. Case report: A female patient, 37 years old with a massive upper gastrointestinal bleeding was referred for emergency admission in a large hospital. She was referred for gastrointestinal endoscopy, detecting active bleeding from esophageal varices, which were submitted to sclerotherapy. The subsequent investigation confirmed chronic liver disease and diffuse saccular dilatation of intrahepatic bile ducts with diffuse hepatic fibrosis, consolidating the diagnosis of Caroli`s Syndrome. Currently, the patient is in follow up, awaiting liver transplantation. Final considerations: the study of this Caroli's syndrome case confirms the importance of this disease as a differential diagnosis in patients presenting with clinical syndromecompatible with portal hypertension and cholangitis, requiring early diagnosis due to increased risk of cholangiocarcinoma, and often the liver transplant is the best treatment option.

[Caroli's syndrome].

OBJECTIVE: Caroli's syndrome is a rare autosomal recessive hereditary disease. Here a case of Caroli's syndrome associated with medullary sponge kidney was reported. The patient was a 2-years and 10 months-old boy. He presented with hepatosplenomegaly. Fever, abdominal pain or jaundice was not found. The imaging examination showed intrahepatic bile duct dilation, splenomegaly, medullary sponge kidney and nephrocalcinosis. After introduction of the case, this paper reviewed the clinical characteristics, diagnosis and treatment of Caroli's syndrome.

Successful liver transplantation in a child with Caroli's disease.

CD is a rare autosomal recessive disease, characterized by multifocal cystic dilatation of intrahepatic bile ducts. The course of the disease is characterized by intrahepatic cholelithiasis, recurrent episodes of cholangitis, because of cholelithiasis, hepatic abscesses often ending in death caused by uncontrolled infection. Other conditions such as choledochal cyst and renal cystic disease are frequently associated, and patients have a higher risk for the development of cholangiocarcinoma. Endoscopic drainage of the bile duct is palliative and ineffective. OLT appears to be the treatment of choice. In monolobar cases partial liver resection has been shown to be a curative therapeutic option. We report on the course of disease in a Turkish girl who was diagnosed with CD in the neonatal period. At the age of 8.2 yr, she received OLT and is in good health 57 months post-transplantation.

In 1958 Caroli described a rare disease with multifocal, segmental and saccular dilation of the large intrahepatic bile ducts which causes stagnation of bile and formation of bile sludge and stones. This results in recurrent abdominal pain, cholangitis and hepatic abscesses. The diagnosis is confirmed with endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous transhepatic cholangiography (PTC) and the purpose of treatment is to restore normal bile flow. Partial resection of the liver has given good results in patient with localized disease. The prognosis is poor despite drainage of bile and 46% of patients die from sepsis, hepatic abscesses, hepatic failure or portal hypertension. There is more than a hundred fold risk of cholangiocarcinoma. We report a case where a male who had a history of recurrent bouts of abdominal pain and pancreatitis was diagnosed with Caroli's disease. He later developed cholangiocarcinoma. Caroli's disease has not, to our knowledge, been reported in Iceland before.

Caroli's disease: identification and treatment strategy.

Caroli's disease is a rare congenital disease of the liver characterized by cystic dilation of the intrahepatic bile duct. Classic Caroli's disease involves malformations of the biliary tract alone, whereas Caroli's syndrome refers to the presence of associated congenital hepatic fibrosis. Caroli's disease usually presents during childhood and early adulthood. The clinical features of Caroli's disease include jaundice, right upper abdominal pain, and fever due to the associated complications of hepatolithiasis or bacterial cholangitis. Endoscopic or percutaneous cholangiography is the traditional method of diagnosis, but magnetic resonance cholangiopancreatography is emerging as the diagnostic modality of choice. The treatment for Caroli's disease includes supportive care with antibiotics for cholangitis and ursodeoxycholic acid for hepatolithiasis. Surgical resection has been used successfully in patients with monolobar disease. For patients with diffuse involvement, the treatment of choice is orthotopic liver transplantation.
