Hemobilia refers to bleeding from and/or into the biliary tract and is an uncommon cause of gastrointestinal hemorrhage. Hemobilia has been documented since the 1600s, but due to its relative rarity, it has only been more critically examined in recent decades. Most cases of hemobilia are iatrogenic and caused by procedures involving the liver, pancreas, bile ducts, and/or the hepatopancreatobiliary vasculature, with trauma and malignancy representing the two other major causes. A classic triad of right upper quadrant pain, jaundice, and overt upper gastrointestinal bleeding has been described, but this is present in only 25-30% of patients with hemobilia...

Introduction: Nonfunctional pituitary adenomas are treated surgically, and even partial resection can improve or eliminate clinical symptoms. Notably, progression requires further intervention, which presents an increased risk, especially in older patients. This study investigated whether the histopathological characteristics of nonfunctional adenomas could predict recurrence. Materials and Methods: Data were obtained retrospectively from 30 patients who underwent surgery for the partial resection of pituitary adenomas...

Systemic artery embolism is a rare complication of CT-guided lung biopsy. Immediate clinical and radiological recognitions are crucial for rapid intervention and prevention of fatal outcome. Although hyperbaric oxygen is the suggested treatment of mildly symptomatic systemic artery embolization, aspiration of air should be considered as part of the management in cases of cardiac arrest.

Interventional radiology in veterinary medicine was adapted from techniques developed in human medicine, and has a variety of applications to treat disease in multiple body systems. Fluoroscopy is required for almost all interventional procedures, requiring knowledge of proper safety techniques for working with ionizing radiation. There are a wide variety of catheters, wires, sheaths, stents, and embolics used in veterinary medicine. Familiarity with their indications and sizing compatibility is essential for procedural success...

INTRODUCTION: /Objective: Hydrocephalus is a common neurosurgical disorder that can lead to significant disability or death if not promptly identified and treated. Data on the burden of hydrocephalus in low-income countries is limited given lack of radiological resources for the diagnosis of this condition. Here, we present an analysis of patterns of hydrocephalus from a large sample of head CTs performed at a public hospital in rural Haiti, a low-income country in the Caribbean. METHODS: We analyzed reports from 3614 head CTs performed between July 2013 and January 2016 for findings that were consistent with a diagnosis of hydrocephalus (report indicating "hydrocephalus," "ventriculomegaly," or "enlargement of the ventricles")...

Parotid gland lesions in children can be divided into benign or malignant. The age of the patient helps narrow the differential diagnosis, with vascular and congenital lesions being more frequent in the 1st year of life, while solid tumors are more frequent in older children. Inflammatory disease usually has rapid onset in comparison with that of neoplastic or congenital processes, which have more gradual clinical evolution. Currently, multiple imaging techniques are available to study the parotid region, such as US, CT, and MRI...

Acute pancreatitis is a potentially life-threatening disease, which is morphologically classified into interstitial edematous or necrotizing pancreatitis. According to the revised Atlanta classification, mild, moderate and severe clinical courses are differentiated regarding local and systemic complications as well as concomitant organ failure. In the initial disease phase, the therapeutic measures are focused on (aggressive) volume replacement, early enteral nutrition and adequate analgesia. Characteristic in the course of severe acute pancreatitis are abdominal necroses, which require individualized and interdisciplinary treatment with antibiotic therapy, drainage and definitive necrosectomy...

BACKGROUND: Acute care surgery (ACS) was proposed to improve emergency general surgery (EGS) care; however, the extent of ACS model adoption in the United States is unknown. A national survey was conducted to ascertain factors associated with variations in EGS models of care, with particular focus on ACS use. METHODS: A hybrid mail/electronic survey was sent in 2015 to 2,811 acute care hospitals with an emergency room and an operating room. If a respondent indicated that the approach to EGS was a dedicated clinical team whose scope encompasses EGS (± trauma, ± elective general surgery, ± burns), the hospital was considered an ACS hospital...
