AbstractSystematic and standardized evaluation of superficial venous disease, guided by knowledge of the various clinical presentations, venous anatomy, and pathophysiology of reflux, is essential for appropriate diagnosis and optimal treatment. Duplex ultrasonography is the standard for delineating venous anatomy, detecting anatomic variants, and identifying the origin of venous insufficiency. This article reviews tools and techniques essential for physical examination and ultrasound assessment of patients with superficial venous disease.

The Canadian Association of Radiologists Incidental Findings Working Group consists of both academic subspecialty and general radiologists and is tasked with adapting and expanding upon the American College of Radiology incidental findings white papers to more closely apply to Canadian practice patterns, particularly more comprehensively dealing with the role of ultrasound and pursuing more cost-effective approaches to the workup of incidental findings without compromising patient care. Presented here are the 2021 Canadian guidelines for the management of pancreatic incidental findings. Topics covered include anatomic variants, fatty atrophy, pancreatic calcifications, ductal ectasia, and management of incidental pancreatic cysts.

AbstractAnatomic variants in the head and neck are quite numerous and occur frequently: a minority of them increase the risk of complications during surgical procedures and may be visualized on cross-sectional images. As some of these complications are potentially fatal, awareness (and accurate reporting) of such variants is a basic responsibility of radiologists, particularly when surgery in the pertinent anatomic area is under consideration.

Abstract Background A wide variety of congenital thoracic aortic variants and pathological anomalies could be assessed recently in diagnostic and interventional radiology. Multi-detector computed tomography (MDCT) is one of the most important non-invasive diagnostic tools for their detection. The aim of the study was to evaluate role of MDCT scanning for diagnosis of thoracic aortic anatomic variants and diseases in pediatric patients. Results Thirty patients (15 male and 15 female), mean age (8.49 ± 20.29 months) were diagnosed with different thoracic aortic anomalies by MDCT then confirmed by surgical results. MDCT was more sensitive than echocardiography in detection of hypo plastic arch, vascular rings, interrupted aortic arch anomalies, and aortic coarctation. Both MDCT and echocardiography showed 100% sensitivity in their detection of TGA, TOF, and PDA. MDCT detected 6 cases of right-sided aortic arch while echo missed 2 cases. Different aortic arch branching patterns and coronary origin were better demonstrated by MDCT. Conclusion 320-Multi-detector computed tomography is a reliable tool for optimal detection of thoracic aortic anomalies and preoperative planning.

Proper Interpretation

Keen observation and precise documentation have become increasingly important in the physical evaluation of a child who may have been sexually abused. The task of proper interpretation of these [See table in the PDF file] physical findings depends on the recognition of normal anatomy. Much work has been done to differentiate normal anatomic variants from physical changes resulting from injury.1-7 In a recent study, healthy female newborns were examined to establish the presence of a white midline streak in the posterior vestibule.8 In the initial phase of this study, 123 newborns were examined. A white linear structure in the mid-posterior vestibule, termed linea vestibularis (LV), was found in 10% (n = 13) of the group and a white spot in the mid-posterior vestibule, termed partial linea vestibularis (PLV), was found in 14% (n = 17) of the group.

Cerebrovascular Risk

Introduction : Bilateral ACA strokes are rare, with one stroke registry reporting 2 cases out of 1490 strokes (1). These strokes are even less common in the absence of anatomic variants, such as an azygos ACA. Diagnosis may be difficult given the variability in clinical presentation. Methods : This is a case report. Results : A 51‐year‐old right handed man with no cerebrovascular risk factors on no antithrombotic medications presented two hours from last known well with complaints of generalized weakness, inability to speak or move, and feeling numb all‐over during intercourse. He reported rapid improvement in symptoms. Emergency room exam was notable for right leg weakness (3/5) and left leg plegia with intact sensation. Hoover’s sign was positive in the left leg and the patient was able to bear some weight while standing with a two‐person assist. A computed tomography angiogram (CTA) of his head and neck was preliminarily interpreted as normal. No azygos ACA or single internal carotid artery origin for the ACAs were present. His exam improved to an isolated left foot dorsiflexor and plantar flexor weakness. The decision was made not to use thrombolytics based on his symptoms and exam which were improving and not entirely consistent with acute stroke. Brain magnetic resonance imaging demonstrated bilateral parasagittal acute strokes. It was later noted the that non‐contrast head CT demonstrated bilateral hyperdense ACAs. Conclusions : This case demonstrates the difficulty in diagnosing bilateral ACA infarcts in a previously healthy adult in the setting of whole‐body numbness and positive Hoover’s sign. In retrospect, his transient inability to speak or move may have been transient akinetic mutism or callosal disconnection syndrome. Additionally, this case emphasizes the importance of evaluating for the hyperdense ACA sign (2) in patients complaining of bilateral leg weakness.
