BACKGROUND: There are limited data on utility of diffusion-weighted imaging (DWI) in the evaluation of pediatric liver lesions. OBJECTIVE: To determine whether qualitative and quantitative DWI can be used to differentiate benign and malignant pediatric liver lesions. MATERIALS AND METHODS: We retrospectively reviewed MRIs in children with focal liver lesions to qualitatively evaluate lesions noting diffusion restriction, T2 shine-through, increased diffusion, hypointensity on DWI and apparent diffusion coefficient (ADC) maps, and intermediate signal on both, and to measure ADC values...

BACKGROUND: The popularity of laparoscopic liver resection (LLR) is spreading, worldwide, because the intraoperative blood loss is less than for open hepatectomy and it is associated with a shorter hospitalization period [1-6]. During LLR, intraoperative hemostasis is difficult to achieve, unlike during laparotomy where bleeding can be stopped instantly [7-10]. Our LLR method for the treatment of hepatocellular carcinoma (HCC) includes maximal control of intraoperative bleeding using a monopolar soft-coagulation device...

The hypervirulent K1 serotype Klebsiella pneumoniae is responsible for a new invasive syndrome, typically associated to hepatic abscesses with extra-hepatic complications. Initially described in Taiwan, it has significantly spread to several Asian countries and more recently to Europe and North America, thus constituting an emerging and global problem. The authors describe a case report of a 64-years-old portuguese caucasian woman without any previous diseases or epidemiological risk factors such as trips or contact with Asian products or population, diagnosed with a pyogenic liver abscess with pleural effusion caused by this hyper-virulent strain...

Liver abscesses constitute a prominent concern regarding animal health and profitability of the beef industry. Our objective was to evaluate potential biliary and blood indicators of liver abscesses. Twenty-nine beef bulls (initially averaging 356±70.5 kg and 253±30 days of age) were fed a high-concentrate diet during a performance test of 112 days, during which blood was collected at nine time points spaced 0.5-13 days apart within 56 days before slaughter. At the abattoir, blood and bile were collected and livers were inspected for liver abscesses...

BACKGROUND: "Hilar en bloc resection" using a no-touch technique has been advocated as a standard procedure in right-sided hepatectomies for treatment of perihilar cholangiocarcinoma (PHC). In principle, it has never been reported for left-sided tumors. The aim is to describe the procedures of total hilar en bloc resection with left hemihepatectomy and caudate lobectomy (THER-LH) for advanced PHC and discuss feasibility and clinical significance of this novel technique. METHODS: A retrospective study using a prospectively maintained database was performed to identify eight patients who had received THER-LH for advanced PHC from January 2013 to December 2015...

This report describes a 77-year-old man with cutaneous mycosis caused by Scedosporium dehoogii while taking oral betamethasone and tacrolimus for the treatment of rheumatoid arthritis. At examination in our clinic, the patient had multiple cystic lesions and nodules with slight tenderness, varying in size up to 4 cm, on his left knee and shin. He had not noticed any traumatic injury at the site of the lesions. Fungal cultures of samples taken from the abscesses, scales, and crusts of the lesions yielded white, later grayish brown, fluffy surfaced colonies...

Bile duct hamartoma (BDH) is a rare liver disease with a rising incidence in recent years. A retrospective study on BDH patients between June 2007 and December 2015 was conducted. All the medical records, including clinical, imaging and pathological characteristics, were retrieved. Follow-up data were obtained by telephone communication. The majority of the patients had no symptoms and the laboratory tests were normal. The appearance on ultrasound examination was variable. The lesion exhibited low density on plain computed tomography and no enhancement in 4 cases, and inhomogeneous enhancement in 1 case...

The development of pyogenic hepatic abscess resulting from perforation of the gastrointestinal tract is a rare pathologic finding. It is a condition that can be fatal making early detection and subsequent removal of the inciting foreign body critical to avoid more deleterious sequela. Yet, its initial presentation tends to be nonspecific and typically is only discovered once surgical investigation into the cause of persisting abscess formation is performed. In this study, laparoscopic treatment of a 52-year-old male with a non-resolving hepatic abscess due to transmural gastrointestinal perforation of a toothpick is presented...

In the context of medical three-dimensional (3D) printing, in addition to 3D reconstruction from cross-sectional imaging, graphic design plays a role in developing and/or enhancing 3D-printed models. A custom prototype modular 3D model of the liver was graphically designed depicting segmental anatomy of the parenchyma containing color-coded hepatic vasculature and biliary tree. Subsequently, 3D printing was performed using transparent resin for the surface of the liver and polyamide material to develop hollow internal structures that allow for passage of catheters and wires...

OBJECTIVE: This study aimed to investigate the correlation between the transient segmental enhancement (TSE) of liver abscesses on contrast-enhanced ultrasound (CEUS) imaging and contrast-enhanced computed tomography (CT) scans. METHODS: In total, 42 abscesses in 38 patients were evaluated with real-time CEUS and contrast-enhanced CT imaging. The CT imaging and CEUS examinations were performed within one to 2 days of each other in all cases. The initial reports of the observations of TSE on CEUS scans were correlated later with the findings of TSE on contrast-enhanced CT images...

BACKGROUND: Definitive treatment for late hepatic artery thrombosis (L-HAT) is retransplantation (re-LT); however, the L-HAT-associated disease burden is poorly represented in allocation models. METHODS: Graft access and transplant outcome of the re-LT experience between 2005 and 2016 was reviewed with specific focus on the L-HAT cohort in this single-center retrospective study. RESULTS: Ninety-nine (5.7%) of 1725 liver transplantations were re-LT with HAT as the main indication (n = 43; 43%) distributed into early (n = 25) and late (n = 18) episodes...

BACKGROUND: Follicular nodular hyperplasia (FNH) is a common benign liver tumor for which conservative management is indicated. Surgical or interventional management is indicated in symptomatic cases. Transarterial embolization (TAE) has been extensively used to manage unresectable liver tumors. Sublimation describes a change of physical state from solid to gas. Hepatic tissue sublimation following TAE has so far not been reported in medical literature. CASE PRESENTATION: A 30 year - old male patient presenting with pain to the upper abdomen due to a large FNH was managed with TAE...

Fusobacterium species are well described as the causative pathogen in Lemierre's syndrome, a suppurative thrombophlebitis of the jugular vein. However, they are less recognized for a unique variant of Lemierre's syndrome presenting with invasive intraabdominal infection and associated portal vein thrombosis. We describe a case of Fusobacterium nucleatum with hepatic abscess and septic pylephlebitis.

The most common extraintestinal complication of Entamoeba histolytica is amoebic liver abscess (ALA). Hepatic vein and inferior vena cava (IVC) thrombosis are rare but well-documented complications of ALA, typically attributed to mechanical compression and inflammation associated with a large abscess. We present a case of a previously healthy 43-year-old Canadian man presenting with constitutional symptoms and right upper quadrant abdominal pain. He was found to have thrombophlebitis of the IVC, accessory right hepatic vein, and bilateral iliac veins...
