Prognostic role of magnetic resonance imaging of the abdomen with intravenous contrast and magnetic resonance cholangiopancreatography in primary sclerosing cholangitis.

Objective: To evaluate the usefulness of Anali scores, determined by magnetic resonance imaging, for predicting the prognosis of primary sclerosing cholangitis (PSC) and to analyze interobserver variability, as well as to assess the impact of periportal edema and heterogeneous signal intensity on diffusion-weighted imaging of the liver.

Materials And Methods: This was a retrospective cohort study of 29 patients with PSC and baseline magnetic resonance imaging. Anali scores, without gadolinium (0-5 points) and with gadolinium (0-2 points), were calculated by two radiologists.

Enhancing ACLF prediction by integrating sarcopenia assessment and frailty in liver transplant candidates on the waiting list.

Background & Aims: Malnutrition, sarcopenia, and frailty are prevalent in cirrhosis. We aimed to assess the correlation between assessment tools for malnutrition, sarcopenia, and frailty in patients on the liver transplant (LT) waiting list (WL), and to identify a predictive model for acute-on-chronic liver failure (ACLF) development.

Methods: This prospective single-center study enrolled consecutive patients with cirrhosis on the WL for LT (May 2019-November 2021).

Radiomics and Machine Learning for prediction of two-year disease-specific mortality and KRAS mutation status in metastatic colorectal cancer.

Purpose: Colorectal cancer is usually accompanied by liver metastases. The prediction of patient evolution is essential for the choice of the appropriate therapy. The aim of this study is to develop and evaluate machine learning models to predict KRAS gene mutations and 2-year disease-specific mortality from medical images.

[Epidemiology of patients with hepatocellular carcinoma in a University hospital].

Hepatocellular carcinoma is the most common primary liver tumor, with 905 677 diagnosed cases and 830 180 deaths, in 2020 worldwide. In Argentina, it accounts for the 9th cause of death for cancer in men and the 10th in women. Unlike other highly-prevalent tumors, scientific evidence for most therapeutic options is limited mainly to small cohorts and retrospective studies.

Hydatid liver disease with portal vein invasion, cavernous transformation and portal biliopathy.

Hydatid disease is a zoonotic parasitic disease, most commonly affecting the liver, lungs and nervous system. Portal vein involvement by hydatid cyst disease is very rare with only few cases published to our knowledge. We describe a case involving a 53-year-old woman with portal vein invasion, cavernous transformation and portal biliopathy.

Sarcopenia HIBA score predicts sarcopenia and mortality in patients on the liver transplant waiting list.

Sarcopenia is a prevalent condition that predicts prognosis in patients awaiting liver transplantation (LT). The gold standard for the diagnosis of sarcopenia is the assessment of the muscular area at L3 with computed tomography (CT) scan (skeletal muscle index [SMI]), but the routine use of CT scan is limited in clinical practice. Thus, we designed a single-center observational study aimed to evaluate the clinical factors associated with the presence of sarcopenia by SMI, and to build a score capable of predicting or excluding the presence of sarcopenia in patients on the LT waiting list (WL).

Bowel angioedema induced by iodinated contrast media.

We present the case of a patient with small bowel angioedema induced by iodinated contrast media during computed tomography. It is important to know this entity and to differentiate it from other intestinal diseases in order to avoid inappropriate treatment.

Follicular Cholecystitis Mimicking Xanthogranulomatous Cholecystitis and Malignancy: A Case Report.

Chronic follicular cholecystitis (CFC) is a rare pathology characterized by prominent lymphoid follicles in the lamina propria distributed throughout the gallbladder wall. It has also been mentioned in the literature as lymphoid hyperplasia and pseudolymphoma. CFC represents less than 2% of cholecystectomies.

Assessment of SE-MRE-derived shear stiffness at 3.0 Tesla for solid liver tumors characterization.

Objectives: To evaluate the feasibility and diagnostic value of using a 2D spin-echo MR elastography (SE-MRE) sequence at 3.0 Tesla for solid focal liver lesions (FLL) characterization.

Methods: This prospective study included 55 patients with solid FLL (size > 20 mm), who underwent liver SE-MRE at 3 Tesla between 2016 and 2019.

Argentinian clinical practice guideline for surveillance, diagnosis, staging and treatment of hepatocellular carcinoma.

The A.A.E.

Cystatin C and Sarcopenia Predict Acute on Chronic Liver Failure Development and Mortality in Patients on the Liver Transplant Waiting List.

Background: Cystatin C (CysC) is an early biomarker of renal dysfunction scarcely studied in patients awaiting liver transplantation (LT). Sarcopenia is frequent in cirrhosis and impacts prognosis. We aimed to assess the capability of these factors to predict survival and acute-on-chronic liver failure (ACLF) in patients awaiting LT, as well as early post-LT outcomes.

Early pancreatic cancer in IgG4-related pancreatic mass: A case report.

Background: IgG4-related disease can manifest diversely, including autoimmune pancreatitis and IgG4-related cholangiopathy. We are reporting a very unusual cause of pancreatic cancer triggered in a previously unknown IgG4-related disease.

Case Summary: A 75-year-old man was diagnosed with a 43 mm × 33 mm pancreatic head tumor after consulting for abdominal pain and jaundice.

Malignant transformation of hepatocellular adenoma in a young female patient after ovulation induction fertility treatment: A case report.

Background: Hepatocellular adenoma (HCA) is a rare benign liver tumor usually affecting young women with a history of prolonged use of hormonal contraception. Although the majority is asymptomatic, a low proportion may have significant complications such as bleeding or malignancy. Despite responding to the hormonal stimulus, the desire for pregnancy in patients with small HCA is not contraindicated.

Expected and Unexpected Imaging Findings after Y Transarterial Radioembolization for Liver Tumors.

Transarterial radioembolization (TARE), also called radioembolization or selective internal radiation therapy, is an interventional radiology technique used to treat primary liver tumors and liver metastases. The aim of this therapy is to deliver tumoricidal doses of radiation to liver tumors while selecting a safe radiation dose limit for nontumoral liver and lung tissue. Hence, correct treatment planning is essential to obtaining good results.

Endoscopic Ultrasound in the Diagnosis of Pancreatoduodenal Groove Pathology: Report of Three Cases and Brief Review of the Literature.

The pancreatoduodenal groove is a small area where pathologic processes involving the distal bile duct, duodenum, pancreatic head, ampulla of Vater, and retroperitoneum converge. Despite great advances in imaging techniques, a definitive preoperative diagnosis is challenging because of the complex anatomy of this area. Therefore, surgical intervention is frequently required because of the inability to completely exclude malignancy.

Hepatic metastasis of thymoma: case report and immunohistochemical study.

Thymomas are rare tumours characterised by their slow growth and capacity to invade directly by contiguity. While distant dissemination is infrequent, all sub-types of thymoma have the capacity to metastasise to extrathoracic organs. We present here the case of a female patient with a liver mass discovered 13 years after the removal of a mediastinal thymoma and after ten years from thyroidectomy for papillary carcinoma.

[Bilateral pneumothorax complicating cavitary pulmonary metastases in angiosarcoma].

Metastatic pulmonary angiosarcomas are a common complication of a rare condition. Generally, they are presented as peripheral solid nodules, infiltrates, and pleural effusions. We report the case of a 65 year-old man with bilateral recurrent pneumothorax secondary to metastatic cavitary lesions from angiosarcoma of the scalp.

Groove pancreatitis vs groove pancreatic adenocarcinoma. Report of two cases and review of the literature.

Groove pancreatitis (GP) is a rare form of segmental chronic pancreatitis affecting the groove area (anatomic space between the head of the pancreas, the duodenum and the common bile duct). Its clinical and radiological presentation may be similar to groove pancreatic adenocarcinoma (GPA). Nevertheless, treatment and prognosis are totally different.

Focal nodular hyperplasia and hepatic adenoma: current diagnosis and management.

Benign liver tumors are common lesions that can be classified into cystic and solid lesions. Cystic lesions are the most frequent; however, they rarely represent a diagnostic or therapeutic challenge. In contrast, solid lesions are more difficult to characterize and management remains controversial.

New surgical strategy to induce liver hypertrophy: role of MDCT-volumetry to monitor and predict liver growth.

Background/aims: To describe the role of MDCT-volumetry to monitor and predict liver hypertrophy in a recently introduced surgical technique in patients needing hepatectomy.

Methodology: This prospective study was approved by the local research and ethics committee and patient informed consent was obtained. Twelve consecutive patients were selected for associating liver partition and portal vein ligation for staged-hepatectomy procedure.

MDCT findings after hepatic chemoembolization with DC-beads: what the radiologist needs to know.

Transcatheter arterial chemoembolization with drug-eluting beads (TACE-DC-beads) is a new local treatment for primary or metastatic liver tumors. Despite technical efforts to achieve highly selective embolization of the tumor-supplying vessels, small, or large insults to the non-tumorous parenchyma are inevitably induced by the embolic materials or procedure itself. Parenchymal changes following TACE-DC-beads include bile duct injuries (bile duct dilatation, periportal edema, and bilomas), obliteration of intrahepatic portal vein branches, hypodense ill-defined areas, and perilesional parenchymal enhancement.

Radiological versus histopathological diagnosis of usual interstitial pneumonia in the clinical practice: does it have any survival difference?

Background: Recent studies have shown that quantification of specific histopathologic features found in usual interstitial pneumonia (UIP) are useful in defining a prognosis, suggesting the need of biopsy in all patients.

Objectives: This study examines whether UIP-associated mortality is different in patients diagnosed by high-resolution computed tomography (HRCT) features considered definite of UIP and in patients with no definite radiological diagnosis that required histological confirmation of diagnoses.

Methods: Forty-five patients were included (30 males, mean age 65.

[Multiple rib fractures associated with cough].

Cough is a common symptom in ambulatory practice and in general does not require specific treatment. When the cough is chronic it can provoke complications such as syncope, pneumothorax or, rarely, rib fractures. We report a case of a patient with multiple rib fractures caused by cough.
