Background. Fascioliasis is a disease caused by the trematode Fasciola hepatica. Cholangitis is a common clinical manifestation. Although fascioliasis may show various radiological and clinical features, cases without biliary dilatation are rare. Case report. We present unique ultrasound (US) and magnetic resonance cholangiopancreatography (MRCP) findings of a biliary fascioliasis case which doesn’t have biliary obstruction or cholestasis. Radiologically, curvilinear parasites compatible with juvenile and mature Fasciola hepatica within the gallbladder and common bile duct were found. The parasites appear as bright echogenic structures with no acoustic shadow on US and hypo-intense curvilinear lesions on T2 weighted MRCP images. Conclusions. Imaging studies may significantly contribute to the diagnosis of patients with subtle clinical and laboratory findings, particularly in endemic regions.

Chronic pancreatitis (CP) describes long-standing inflammation of the pancreas, which leads to irreversible and progressive inflammation of the pancreas with fibrosis. CP also leads to abdominal pain, malnutrition, and permanent impairment of exocrine/endocrine functions. However, it is difficult to assess CP pathologically, and imaging modalities therefore play an important role in the diagnosis and assessment of CP. There are four modalities typically used to assess CP. Pancreatic duct features are assessed with magnetic resonance cholangiopancreatography (MRCP) and endoscopic retrograde cholangiopancreatography (ERCP). However, ERCP is a rather invasive diagnostic modality for CP, and can result in adverse events such as post-ERCP pancreatitis. Computed tomography (CT) is often the most appropriate initial imaging modality for patients with suspected CP, and has high diagnostic specificity. However, CT findings typically only appear in advanced stages of CP, and it is difficult to detect early CP. Endoscopic ultrasonography (EUS) provides superior spatial resolution compared with other imaging modalities such as CT and magnetic resonance imaging (MRI), and is considered the most reliable and efficient diagnostic modality for pancreatic diseases. The EUS-based Rosemont classification plays an important role in diagnosing CP in clinical practice. Evaluation of tissue stiffness can be another option to assess the diagnosis and progression of CP, and MRI and EUS can be used to assess CP not only with imaging, but also with elasticity measurement. MR and EUS elastography are expected to provide new alternative diagnostic tools for assessment of fibrosis in CP, which is difficult to evaluate pathologically.

Us Findings

This study aimed to evaluate the diagnostic accuracy of magnetic resonance cholangiopancreatography (MRCP) and Ultrasound (US) images for the diagnosis of biliary system stones, as well as to assess the consistency between MRCP and US findings. The study sample included 200 cases (90 males and 110 females) with symptomatic biliary system stones between 14 and 82 years. All cases underwent both the US and MRCP imaging for biliary system diagnosis. The study revealed that the most prominent age group with symptoms of biliary system stones was the 33-60-year-old group. It also found that the accuracy of US and MRCP in detecting gallbladder (GB) stones compared with the final diagnosis was 94% and 91%, respectively, with moderate conformity between their results. The accuracy of US and MRCP images in detecting common bile duct (CBD) stones was 61% and 98%, respectively, with fair conformity between their results. In addition, there is a significant agreement between the MRCP and US results in detecting the GB and CBD stones with an agreed percentage of 74% and 71%, respectively. The study concluded that US is the preferred imaging technique for patients with symptomatic gallbladder stones, whereas MRCP is a trustworthy investigation for common bile duct stones.

Primary sclerosing cholangitis (PSC) is a chronic liver disease in which there are inflammation and scarring of the bile ducts leading to fibrosis, destruction and narrowing of the bile ducts, resulting in cholestasis. In the long run, PSC can cause liver cirrhosis and failure. In clinical practice, the diagnosis of PSC is generally based on blood tests and imaging studies (currently preferably magnetic resonance cholangiopancreatography). To make a diagnosis of PSC it is necessary to exclude secondary causes of sclerosing cholangitis. The most common MRI features of PSC concerning bile ducts are: bile duct dilatation, beading, extrahepatic bile duct stenosis, wall enhancement and thickening. The most common MRI features of PSC concerning hepatic parenchyma are: rounded shape of the liver caused by hypertrophy of caudate lobe and left liver lobe, atrophy of the right lobe, enlargement of portal and/or portacaval lymph nodes, peripheral parenchymal inflammation, wedge-shaped confluent fibrosis, heterogeneity of the liver parenchyma, periportal oedema, cirrhosis with indirect signs of portal hypertension such as splenomegaly, ascites and collateral vasculature.

Abstract Introduction Morphological variants of the pancreatobiliary system can predispose to chronic pancreatitis. The goal of the present study is to assess the prevalence of pancreatic duct patterns in the Indian population, both by cadaveric dissection and by magnetic resonance cholangiopancreatography (MRCP). Materials and Methods A total of 15 adult pancreas specimens of unknown age and gender, and 5 fetal pancreas specimens of different gestational ages with the intact second part of duodenum, were dissected by the piecemeal method. For clinical relevance, MRCP images of 103 clinically-diagnosed chronic pancreatitis patients irrespective of their etiology were obtained retrospectively from the existing database and studied. The anatomical patterns were classified as five different types based on the course of the main pancreatic duct and the accessory pancreatic duct and their openings into the duodenal wall, including variants like pancreas divisum and ansa pancreatica. Results In the cadaveric study, the main pancreatic duct was single with a straight course in 46.67% of the adult specimens, and in the MRCP study, the main pancreatic duct showed a descending course in 77.66% of the cases. The most common pattern was type III in both the cadaveric (80%) and radiological (55.33%) studies, and the accessory duct was absent on the MRCP in all type-III cases, while it ended blindly in the cadaveric specimens. Ansa pancreatica (type V) was observed in 1 adult specimen (6.7%), but not in the radiological study. Pancreas divisum (type IV) was observed in the 8 cases (7.76%) cases in the radiological study. Conclusion Knowledge of the anatomical variants of the pancreatic ductal system may be helpful for the radiologists during diagnostic and therapeutic interventional procedures.

Latar Belakang: hepatolitiasis adalah batu empedu pada saluran empedu liver dengan insidensi 20-30% dari semua pasien yang menjalani operasi untuk penyakit batu empedu. Ada beberapa pilihan operasi hepatolitiasis, seperti hepatektomi, eksplorasi common bile duct (CBD), dan drainase saluran intrahepatik atau cholangioenterostomy (access loop procedures), dan teknik perkutaneus. Pada laporan kasus serial ini, akan dibahas aspek pemilihan operasi pada pasien dengan hepatolitiasis. Kasus: kasus pertama adalah laki-laki, 60 tahun, dirawat di Rumah Sakit Dr. Soetomo dengan nyeri abdomen kuadran kanan atas sejak 2 minggu. Diagnosis dengan USG (ultrasonografi) abdomen dan MRCP (magnetic resonance cholangiopancreatography) menunjukkan terdapat beberapa batu di IHBD (intra hepatic bile duct), CHD (common hepatic duct), CBD, GB (gall bladder), dan sistem bilier yang melebar. Pada pasien dilakukan tindakan kolesistektomi, eksplorasi duktus, dan by pass bilio-digestive Roux en Y (access loop procedures). Kasus kedua adalah perempuan, 45 tahun, dirawat di Rumah Sakit Dr. Soetomo dengan didiagnosis batu IHBD dan CBD. Penderita telah dilakukan kolesistektomi sejak 12 tahun yang lalu. Durante operasi ditemukan atrofi lobus kiri hati. Pada pasien, dilakukan operasi dengan eksplorasi duktus, by pass bilio-digestive Roux en Y (access loop procedures), dan hepatektomi lobus kiri. Simpulan: kasus hepatolitiasis jarang terjadi di Rumah Sakit Dr. Soetomo Surabaya. Diagnosis lengkap memerlukan kombinasi modalitas pencitraan. Pembedahan tetap menjadi pilihan utama pengobatan definitif. Menurut strategi terapeutik saat ini untuk hepatolitiasis, hepatektomi tampaknya merupakan pengobatan yang paling efektif untuk pasien dengan hepatolitiasis kiri yang terisolasi jika prosedur pembedahan lain tidak dapat mengatasi semua lesi terkait. Perawatan yang baik dapat memberikan luaran yang baik.
