We present a pictorial review of anomalous origin of the left vertebral artery observed in 5 patients imaged in our after-hours trauma radiology unit within a period of 7 days. We raise the question of whether the incidence of anomalous origin of the left vertebral artery quoted in the radiology literature as 5% is really that low, and suggest that the current increased frequency of cross-sectional imaging could elevate the observed incidence of this anomaly in practice. We discuss the implications of vertebral artery anomalies in the endovascular treatment of aortic arch injuries.

AbstractBackgroundMastoiditis is an otological emergency, and cross-sectional imaging has a role in the diagnosis of complications and surgical planning. Advances in imaging technology are becoming increasingly sophisticated and, by the same token, the ability to accurately interpret findings is essential.MethodsThis paper reviews common and rare complications of mastoiditis using case-led examples. A radiologist-derived systematic checklist is proposed, to assist the ENT surgeon with interpreting cross-sectional imaging in emergency mastoiditis cases when the opinion of a head and neck radiologist may be difficult to obtain.ResultsA 16-point checklist (the ‘mastoid 16’) was used on a case-led basis to review the radiological features of both common and rare complications of mastoiditis; this is complemented with imaging examples.ConclusionAcute mastoiditis has a range of serious complications that may be amenable to treatment, once diagnosed using appropriate imaging. The proposed checklist provides a systematic approach to identifying complications of mastoiditis.

AbstractDue to the growing use of cross-sectional imaging in emergency departments, acute gynaecologic disorders are increasingly diagnosed on urgent multidetector computed tomography (CT) studies, often requested under alternative presumptive diagnoses in reproductive-age women. If clinical conditions and state-of-the-art scanner availability permit, magnetic resonance imaging (MRI) is superior to CT due to its more in-depth characterisationof abnormal or inconclusive gynaecological findings, owing to excellent soft-tissue contrast, intrinsic multiplanar capabilities and lack of ionising radiation.This pictorial review aims to provide radiologists with a thorough familiarity with gynaecologic emergencies by illustrating their CT and MRI appearances, in order to provide a timely and correct imaging diagnosis. Specifically, this second instalment reviews with examples and emphasis on differential diagnosis the main non-pregnancy-related uterine emergencies (including endometrial polyps, degenerated leiomyomas and uterine inversion) and the spectrum of pelvic inflammatory disease.

Cross-sectional imaging techniques are becoming increasingly important for the evaluation of foot and ankle disorders. Computed tomography affords superior depiction of osseous anatomy, and is useful in the assessment of acute fractures, degenerative joint disease, and postoperative alterations. Magnetic resonance imaging is particularly well suited to soft tissue disease, including neoplasms, tendinitis, myopathy, and infection, owing to its excellent contrast discrimination capabilities.

Recognition of key concepts of structural and functional anatomy of the cerebellum can facilitate image interpretation and clinical correlation. Recently, the human brain mapping literature has increased our understanding of cerebellar anatomy, function, connectivity with the cerebrum, and significance of lesions involving specific areas. Both the common names and numerically based Schmahmann classifications of cerebellar lobules are illustrated. Anatomic patterns, or signs, of key fissures and white matter branching are introduced to facilitate easy recognition of the major anatomic features. Color-coded overlays of cross-sectional imaging are provided for reference of more complex detail. Examples of exquisite detail of structural and functional cerebellar anatomy at 7 T MRI are also depicted. The functions of the cerebellum are manifold with the majority of areas involved with non-motor association function. Key concepts of lesion–symptom mapping which correlates lesion location to clinical manifestation are introduced, emphasizing that lesions in most areas of the cerebellum are associated with predominantly non-motor deficits. Clinical correlation is reinforced with examples of intrinsic pathologic derangement of cerebellar anatomy and altered functional connectivity due to pathology of the cerebral hemisphere. The purpose of this pictorial review is to illustrate basic concepts of these topics in a cross-sectional imaging-based format that can be easily understood and applied by radiologists.

Abstract Objective The Inflammatory Bowel Disease (IBD) Medical Home is a care delivery model that provides a comprehensive, patient-centered, coordinated care environment, previously shown to lead to an approximate 50% reduction in unplanned care. However, the frequency and nature of IBD medical home patient phone calls to gastroenterology (GI) fellows after-hours, and the contribution to unplanned care from these encounters, is unknown. Methods We included all patients that were seen in the IBD medical home between 7/1/2015 to 6/30/2016 (n = 293) and examined all phone call activity in the subsequent year: 7/1/2016 to 6/30/2017. After-hours phone calls were defined as documented calls that were routed to on-call GI fellows when the clinic is closed. The details of each after-hours encounter were reviewed, and were categorized by the reason for call, training year of the GI fellow, advice given to patient, and unplanned care outcomes. For comparison, we also tracked frequency of patient calls for symptoms during clinic hours. Demographic information, disease type, disease activity index, quality of life (QoL), and depression/anxiety scores documented most recently to the start of the observation period were included in the analysis. Comparisons were made using Chi-square, T-tests and non-parametric median tests. Results 259 of 293 patients (86.7%) had any documented phone interaction. Only 36 patients (12.3%) placed a total of 63 after-hours phone calls to GI fellows, with calls for symptoms representing the majority (71.4%). Among calls for symptoms (n = 45), patients were advised by GI fellows to present to the emergency department (ED) 44.4% of the time. There was no significant difference in ED recommendations by fellow training level (p = 0.17). Of the 20 ED encounters advised by fellows, 9 (45%) did not result in admission; and 2 patients had new cross-sectional imaging. Of the 11 admissions, 10 also had new cross-sectional imaging, with generation of 10 inpatient IBD consults, as well as 1 surgery for seton placement. After-hours callers were more likely to have Crohn’s disease and higher GAD-7 scores, with trends towards lower SIBDQ scores and higher PHQ-9 scores, but similar disease activity index scores, number of clinic visits, and demographics, compared to patients who called with symptoms during clinic hours (Table 1). Conclusions Among patients established within an IBD medical home model, a small population of patients called after hours resulting in frequent recommendation to present to the ED from GI fellows, however it is unknown if these encounters meaningfully changed their IBD care. Higher psychosocial complexity may influence this care behavior. Further studies of triage processes and educational initiatives aimed at GI fellows may help minimize unplanned ED and inpatient care in this patient population.

The increasing availability of cross-sectional imaging, incredibly magnetic resonance imaging, detects ndings in the patient's scan unrelated to the reason the scan is initially acquired. These ndings refer to the so-called incidental ndings mentioned in the radiology report as "Note made of" without any good impression about their clinical signicance or further management. This type of report leads to anxiety among patients. The radiologist is the rst person to encounter these incidental ndings. Therefore, it is an essential duty of the radiologist to communicate to the clinician about the signicance and urgency/non-urgency of these ndings so that clinicians can decide timely appropriate management. Therefore, this review discusses the prevalence and spectrum of these incidental ndings and the available guidelines for their management.
