Tonsillar herniation and coning is a rare and often late presentation of meningoencephalitis, and is associated with poor neurological outcome. We report the case of a 16-year-old female who presented unresponsive with radiological evidence of tonsillar herniation secondary to meningoencephalitis. She underwent an emergency foramen magnum decompression and C1 laminectomy with full recovery and no residual neurological deficit.

Scrotal pain is a common acute presentation for medical care. Testicular torsion and epididymo-orchitis are two diagnoses for which early detection is critical and their sonographic imaging features have been thoroughly described in the radiologic literature. Other important conditions for which radiologists must be aware have received less attention. This article will highlight key traumatic and non-traumatic causes of acute scrotal pain other than testicular torsion and epididymo-orchitis that may present in the emergency department setting...

To develop an outcome-based NeuroImaging Radiological Interpretation System (NIRIS) for acute traumatic brain injury (TBI) patients that would standardize the interpretation of non-contrast head CTs and consolidate imaging findings into ordinal severity categories that would inform specific patient management actions and that could be used as a clinical decision support tool. We retrospectively identified all patients transported to our emergency department by ambulance or helicopter, for whom a trauma alert was triggered per established criteria and who underwent a non-contrast head CT due to suspicion of TBI, between November 2015 and April 2016...

OBJECTIVE: The ability of emergency physicians (EP) to identify hydronephrosis using point-of-care ultrasound (POCUS) has been assessed in the past using CT scans as the reference standard. We aimed to determine the ability of EP for identifying and grading of hydronephrosis on POCUS using the consensus interpretation of POCUS by emergency radiologists as the reference standard. METHODS: The study was conducted at an urban academic emergency department (ED) as a secondary analysis of previously collected ultrasound data from the EP performed POCUS-databank...

With an ever-expanding use of cross-sectional imaging for diagnostic and therapeutic purposes, there has also been an increase in the need for exposure to such radiological and anatomical views at the undergraduate and postgraduate level to allow for early familiarisation with the relevant anatomy. Cadaveric cross-sections offer an excellent link between the two-dimensional radiological images and the three-dimensional anatomical structures. For such cross-sections to be useful and informative within educational settings, they need to be: (i) safe for students and trainees to handle and (ii) robust enough to withstand repeated handling; as well as (iii) displaying anatomy clearly and accurately...

OBJECTIVE: Our aim was to review the results of pelvic arterial embolization (PAE) performed in the interventional radiology suite. METHOD: The data of all patients in whom pelvic angioembolization was performed was collected from July 2011 to June 2017. Procedures were performed by an experienced interventional radiologist. The clinical and laboratory data, as well as the outcome data, were obtained from the medical records of our hospital. The following parameters were collected for each patient, including the age, gender, presenting symptoms, site of bleeding, catheters used for embolization, material used for embolization, previous computed tomography (CT) scan and/or focused assessment with sonography for trauma (FAST) ultrasound, average hemoglobin before the procedure, and patient clinical status on discharge...

ST-elevation myocardial infarction (STEMI) is a fatal condition. Prompt primary percutaneous coronary intervention is associated with lower mortality. However, community hospitals in Japan lack human and medical resources, and implementation of the same strategies as those used in the USA, such as an on-call cardiologist at the hospital, to achieve a door-to-balloon time of ≤ 90 min appears particularly challenging. Therefore, we used Training for Effective and Efficient Action in Medical Service-Better Process (TEAMS-BP) to develop a new process and assessed its effectiveness in reducing door-to-balloon time...

Current multiparameter MRI protocols integrate structural, physiological, and metabolic information about cancer. Emerging techniques such as arterial spin-labeling (ASL), blood oxygen level dependent (BOLD), MR elastography, chemical exchange saturation transfer (CEST), and hyperpolarization provide new information and will likely be integrated into daily clinical practice in the near future. Furthermore, there is great interest in the study of tumor heterogeneity as a prognostic factor and in relation to resistance to treatment, and this interest is leading to the application of new methods of analysis of multiparametric protocols...

REVIEW
Adam Morton, Stephanie Teasdale
Accurate assessment of the pregnant patient in the ED depends on knowledge of physiological changes in pregnancy, and how these changes may impact on pathology tests, appearance on point-of-care ultrasound and electrocardiography. In addition the emergency physician needs to be cognisant of disorders that are unique to or more common in pregnancy. Part 1 of this review addresses potential deviations in laboratory investigation reference intervals resulting from physiological alterations in pregnancy, and the important causes of abnormal laboratory results in pregnancy...

Committee 2 of the International Commission on Radiological Protection (ICRP) has constructed mesh-type adult reference computational phantoms by converting the voxel-type ICRP Publication 110 adult reference computational phantoms to a high-quality mesh format, and adding those tissues that were below the image resolution of the voxel phantoms and therefore not included in the Publication 110 phantoms. The new mesh phantoms include all the necessary source and target tissues for effective dose calculations, including the 8-40-µm-thick target layers of the alimentary and respiratory tract organs, thereby obviating the need for supplemental organ-specific stylised models (e...

BACKGROUND:  Primary pineal malignant melanoma is a rare type of primary central nervous system melanoma with only 19 cases reported in the literature. CASE REPORT:  We present a case of a 53-year-old man with primary melanoma of the pineal region. He presented to the emergency department with gait unsteadiness and ataxia. Magnetic resonance imaging (MRI) revealed a 22 × 17 × 22-mm mass in the pineal region. On MRI the tumor was hyperintense in T1, isointense in T2, and on T1-weighted images with gadolinium enhancement it appeared homogeneously hyperintense with hypointense spots...

INTRODUCTION: Gallbladder torsion is a rare condition of increasing prevalence in recent years. It is often difficult to diagnose pre-operatively and delayed intervention can lead to significant complications. PRESENTATION OF CASE: We present a case of an 81 year old lady who presented with symptoms of cholecystitis for 24 h with no evidence of cholelithiasis on imaging. She deteriorated within 24 h of admission despite intravenous antibiotics; Emergency laparoscopy was performed which showed the gallbladder malrotated 180 ° with features of necrosis...

The International Commission on Radiological Protection (ICRP) recognises three types of exposure situations: planned, existing, and emergency. In all three situations, the release of radionuclides into the natural environment leads to exposures of non-human biota, as well as the potential for exposures of the public. This paper describes how the key principles of the ICRP system of radiological protection apply to non-human biota and members of the public in each of these exposure situations. Current work in this area within ICRP Task Group 105 is highlighted...
