Torsion of an abdominal organ often leads to an acute abdomen requiring emergency surgery. This report describes the rare case of an acute liver torsion in a 76-year-old man. Surgery revealed dislocation of the left liver lobe, which was flipped over to the right upper abdomen. There was a hypermobile and long falciform ligament and absence of the triangular ligaments. The liver was manually flipped back with subsequent fixation of the umbilical ligament to the diaphragm to prevent reoccurrence. The patient had an uneventful recovery and is doing well 3 months after surgery with good liver function...

High-pressure paint injection injury to the orbit is a rare type of orbital trauma. We present an unfortunate case of high-pressure paint injury to the right orbit of a young patient. High-pressure injection injury presents with a unique injury mechanism and resultant deep tissue damage. The superficial appearance of the entry site injury is deceiving; therefore, a thorough evaluation is necessary. Debridement is usually required if foreign body material is present. Antibiotics and steroids are commonly used in such cases...

Active extravasation into the upper aerodigestive tract is a dramatic and potentially life-threatening complication in patients with head and neck cancers. It prompts presentation to the emergency room and subsequent urgent imaging to identify the source of hemorrhage. Imaging of these patients may be complicated by treatment-altered anatomy, posing a challenge to the emergency radiologist who needs to rapidly identify the presence of active hemorrhage and the potential source vessel. This retrospective review summarizes the clinical and imaging findings of 6 oropharyngeal and oral cavity squamous cell cancer (SCC) patients with active upper aerodigestive tract hemorrhage...

Contrast-enhanced magnetic resonance imaging is considered the imaging modality of choice for invasive fungal sinusitis (IFS); however, it is not feasible to perform emergency CEMRI especially in the setting of COVID-19. The CECT protocol for evaluation of suspected IFS can be modified by using split-bolus, single-phase CT as it provides an optimal soft tissue demonstration of sinonasal disease; extrasinus spread to orbit, and intracranial involvement along with simultaneous opacification of the internal carotid artery and cavernous sinus...

PURPOSE: Ultrasound of the right lower quadrant for appendicitis requires specific training and practice. Improved visualization of the appendix can result in decreased utilization of computed tomography. Increasing the sensitivity of ultrasound for appendicitis thus decreases radiation exposure, reduces cost, and improves the patient healthcare experience in accordance with the three principles of the triple aim designated by the Institute for Healthcare Improvement. The purpose of this study was to examine the effect of a structured training program supplemented by technologist feedback on sonographic visualization of the appendix in a large pediatric health system...

PURPOSE: Gastrointestinal perforation is a significant injury that originates mainly from gastrointestinal ulcers. It is associated with a high rate of morbidity and mortality. The height of the column of the air under the diaphragm can be used to estimate the amount of peritoneal soiling due to viscus perforation. This study aimed to determine the correlation between this estimate and the incidence of morbidity and mortality. METHODS: To achieve this aim, a prospective cohort study was conducted on 83 patients at Kasr al ainy hospital who, between March 2021 and March 2022, presented to the emergency department with free air under the diaphragm at chest X-ray and required surgical intervention for a perforated viscus...

BACKGROUND: The American Association for the Surgery of Trauma (AAST) splenic organ injury scale (OIS) is the most frequently used CT-based grading system for blunt splenic trauma. However, reported inter-rater agreement is modest, and an algorithm that objectively automates grading based on transparent and verifiable criteria could serve as a high-trust diagnostic aid. PURPOSE: To pilot the development of an automated interpretable multi-stage deep learning-based system to predict AAST grade from admission trauma CT...
