Hepatic cyst

Tomoyuki Iwata, Kensuke Adachi, Manabu Takahashi
BACKGROUND: Peliosis hepatis is an uncommon vascular condition characterized by multiple, randomly distributed, blood-filled, and cyst-like cavities throughout the liver. The unique clinical nature consisting of an asymptomatic, benign, and incidental finding sometimes conceals itself even until autopsy. However, the exact pathomechanism remains as yet unproven. METHOD: We encountered the patient with multiple hypervascular masses in the whole liver and investigated the clinicopathological features underlying this condition...

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...

INTRODUCTION: Fast-growing congenital hepatic cysts with intracystic hemorrhage are rare in clinical practice. Additionally, the clinical manifestations of and laboratory and imaging findings for this condition are often nonspecific and are particularly difficult to differentiate from those of hepatobiliary cystadenoma and cystadenocarcinoma, thus posing great challenges for diagnosis and treatment. The 2 case reports presented here aim to analyze the diagnosis and treatment of 2 rare cases of congenital hepatic cysts with intracystic hemorrhage in the Chinese Han population to provide an important reference for the clinical diagnosis and treatment of this condition...

OBJECTIVE: The objective of treatment for polycystic liver disease is to reduce the liver volume and reduce or resolve compression symptoms such as abdominal fullness and abdominal pain due to hepatomegaly. Liver cysts are treated internally by puncture and aspiration of the cyst contents or hepatic artery embolization and surgically by cyst fenestration or hepatectomy, but no clear consensus has been reached concerning their selection. We introduced monoethanolamine oleate (EO) sclerotherapy therapy for liver cysts in 1999 and reported its effectiveness...

: Hemorrhagic rupture is a very rare complication of a simple hepatic cyst. We report the first case of a totally extraperitoneal rupture of a recurrent cyst, occurred in a 73-year-old man who presented with acute right hypochondralgia. Computed tomography revealed the rupture of a large hemorrhagic cyst in the right liver lobe and the formation of a voluminous hematoma in the retroperitoneal space. Despite the absence of hemoperitoneum, the entity of the bleeding led us to perform an urgent and successful surgical intervention...

Echinococcus granulosus (E. granulosus) and Echinococcus multilocularis (E. multilocularis) infections are the most common parasitic diseases that affect the liver. The disease course is typically slow and the patients tend to remain asymptomatic for many years. Often the diagnosis is incidental. Right upper quadrant abdominal pain, hepatitis, cholangitis, and anaphylaxis due to dissemination of the cyst are the main presenting symptoms. Ultrasonography is important in diagnosis. The World Health Organization classification, based on ultrasonographic findings, is used for staging of the disease and treatment selection...

Unlike its family member p53, the p63 gene is rarely mutated in human cancer. However, ΔNp63α protein levels are often elevated in tumors of epithelial origin, such as squamous cell carcinoma and cholangiocarcinoma. In order to study the oncogenic properties of ΔNp63α in vivo, we generated transgenic mice overexpressing ΔNp63α from the Rosa26 locus promoter controlled by K5Cre. We found that these mice spontaneously develop epidermal cysts and ectopic ΔNp63α expression in the bile duct epithelium that leads to dilatation of the intrahepatic biliary ducts, to hepatic cyst formation and bile duct adenoma...

BACKGROUND: In oncologic patients, the liver is the most common target for metastases. An accurate detection and characterization of focal liver lesions in patients with known primary extrahepatic malignancy are essential to define management and prognosis. OBJECTIVES: To assess the diagnostic accuracy of the split-bolus multidetector-row computed tomography (MDCT) protocol in the characterization of focal liver lesions in oncologic patients. PATIENTS AND METHODS: We retrospectively analyzed the follow-up split-bolus 64-detector row CT protocol in 36 oncologic patients to characterize focal liver lesions...

Echinococcus is the smallest of the major tapeworms. Humans are incidental hosts who become infected by exposure to soil contaminated with ova from the feces of the canine definitive hosts. The major species are E. granulosus (cystic echinococcosis) and E. multilocularis (alveolar or sylvatic echinococcosis), both common worldwide but unusual and not reportable in the United States. Human disease is characterized by slowly growing visceral cystic masses often containing daughter cysts and hydatid sand. In nonendemic areas, the clinical evaluation includes imaging, serology, and surgery; metastatic tumor is a major consideration...

Mucinous cystic neoplasms (MCNs) can occur in the pancreas and liver. Classically, these cystic lesions are lined by columnar mucinous epithelium with underlying ovarian-type stroma. It has been proposed that cysts with ovarian-type stroma and nonmucinous epithelium be considered separate entities in both the pancreas and liver. Using a series of 104 pancreatic and 32 hepatic cases, we aimed to further characterize the epithelium present in MCNs. Mucinous epithelium was defined as pancreatic intraepithelial neoplasia-like columnar cells with pale pink/clear apical mucin...

Uridine 5'-diphospho-glucuronosyltransferase (UGT) liver activity was measured using estradiol-17β as a substrate in dairy cows with follicular cysts. The activity was significantly lower than that in dairy cows with normal estrous cycles (P<0.01). Liver disorders, such as fatty liver and hepatitis, were observed in half cows with follicular cysts, and liver UGT activity was lower than that in cows with normal estrus cycles. In addition, the liver UGT activity was significantly lower in dairy cows with follicular cysts without liver disorders than in dairy cows with normal estrous cycles...

BACKGROUND: Tumour markers are substances produced by the tumour itself, or by the host in response to a tumour. These markers could be measured either in the blood or in body secretions. One of the most common tumour markers used in gastrointestinal diseases is Ca 19-9. It is the marker most used for pancreatic cancer, but can be elevated in many benign processes. Thus, it is not a specific marker. CLINICAL CASE: The case is presented of a male patient with 4 years of moderate abdominal pain, weight loss, and persistent elevation of Ca 19-9...

Cystic Echinococcosis is a parasitic disease with cosmopolitan distribution caused by the tape worm Echinococcus granulosus. Fibrous layer is developed around the cyst as a host immune response reaction. The aim of this study was to evaluate the rate of IL-4 gene expression in fibrous layer of bovine and ovine hepatic hydatid cysts using quantitative technique of Real-Time PCR. In this descriptive study the samples of hydatid cyst fibrous layer were taken from 6 bovine and 6 ovine hepatic hydatid cysts. Samples of normal liver tissue close to the cyst were also taken as controls...
