ceVUS is a radiation-free and sensitive examination to detect vesicoureteral reflux and image the urethra in children using ultrasound (US) and intravesical administration of an ultrasound contrast agent (UCA). Due to the growing interest to perform ceVUS in children, a urinary bladder phantom was developed to teach the technical aspects of the ceVUS examination. Here we describe the preparation and utility of this reusable phantom as a tool to simulate the UCA administration, distribution and the effect of different US parameters on the UCA appearance in the bladder.

Anorectal malformations (ARMs) are a heterogenous group of congenital anomalies involving the distal rectum and anus that are often associated with other anomalies. Neonates with ARMs may be identified at birth or prenatally and, upon delivery, receive a myriad of imaging tests to characterize the type of ARM and associated anomalies. Recent literature supports the use of transperineal ultrasound in the initial assessment of neonates with ARMs, with the Society of Pediatric Radiology recommending its use in the imaging algorithm for ARMs. Transperineal ultrasound, if adequately performed, allows evaluation of the location of the distal rectal pouch and the anatomy and location of any rectourogenital fistulas. In this educational poster, we review the clinical presentation and classification ARMs and discuss the role of transperineal ultrasound in the initial assessment of cases. We then describe common sonographic findings of ARMs on transperineal ultrasound using examples from our own institution. Our goal is to familiarize pediatric radiologists with this heterogenous group of congenital anomalies and the clinical utility of transperineal ultrasound in characterizing this pathology.

Congenital high airways obstruction sequence (CHAOS) refers to a relatively rare fetal anomaly caused by high airway obstruction (tracheal or laryngeal) caused by atresia or stenosis. Similar imaging findings can be seen with airway obstruction due to oropharyngeal or neck masses such as teratoma. Antenatal imagining findings include but not limited to dilated fluid filled trachea and proximal bronchi, bilateral enlarged echogenic lungs with relative small sized midline heart, flattening or eversion of the diaphragm, feta ascites and anasarca and polyhydramnios. The prognosis is overall poor, however it is improved after planning for delivery and performing EXIT procedure (ex utero intrapartum treatment) with tracheostomy.
We present a case of a 20-year-old female G1P0 at 25 weeks of gestation diagnosed with Congenital high airways obstruction sequence (CHAOS) with typical features on prenatal ultrasound and fetal MR. Delivery was planned and an EXIT procedure was performed and the newborn survived. Read More

Point of Care Lung ultrasound has proven in multiple studies to be superior to CXR to diagnose pneumonia in children especially in limited resource settings. This non-radiating, portable and adaptable technique, brings an opportunity to detect pneumonia with higher accuracy than CXR. Ultrasound imaging interpretation is challenging. To deal with this complexity, we created a "brightness profiles" data reduction technique to identify specific anatomical structures identified by lung ultrasound using artificial intelligence. We use this technique to demonstrate how data reduction can help identify common anatomical landmarks and abnormal findings, and aid in the interpretation of ultrasound diagnosed pediatric pneumonia.

Children and young adults can present with breast complaints in the emergency setting and ultrasound is typically the initial imaging modality of choice for work-up. While many sonographic findings are benign, there are rare presentations of indeterminate and suspicious masses. In these cases, radiologists and clinicians involved in these patient's care may be unfamiliar with the diagnosis and management of lesions that warrant follow-up with dedicated breast imagers. This study is designed to analyze the common characteristics of pediatric breast complaints from the emergency department and if follow-up care was recommended and pursued. Read More

Ultrasound is a common screening examination performed in infants prior to closure of osseous posterior elements. Although radiologists with pediatric neuroradiology subspecialty training may be very familiar with many abnormalities encountered sonographically, pediatric radiologists without pediatric neuroradiology subspecialty training are often less familiar. Further, the ultrasound appearance of abnormalities of infant spine may be less well known than appearance on MRI. The purpose of this educational review is to demonstrate normal appearance of infant spine and illustrate abnormalities that are frequently and infrequently encountered during screening ultrasound evaluation, with MRI for comparison.

Ultrasound is typically the first-line imaging modality for the evaluation of superficial soft tissue masses in the pediatric population. While certain superficial soft tissue masses have a classic appearance on ultrasound, others may have a nonspecific appearance and may vary in their sonographic characteristics. This can make a definitive diagnosis and follow-up recommendations difficult, especially for trainees.

We aim to provide a basic overview of some of the common and less common superficial soft tissue masses that may be encountered in pediatric imaging, and introduce a novel, structured algorithmic approach for evaluating these lesions on ultrasound. The algorithm will assist the radiologist in reaching a definitive diagnosis or narrowing the differential such that a helpful recommendation for further workup can be made. For example, the algorithm will include internal vascularity, border distinctness, cystic or solid components, presence or absence of calcifications, and location in the body and within the superficial soft tissue layers. Pictorial examples of each sonographic feature in the algorithm will provide further assistance.

Pathologies will include but not be limited to: pilomatricoma, glanuloma annulare, epidermal inclusion cyst, ganglion cyst, abscess/infection, lipoma, hematoma, lymph nodes, vascular anomalies, and soft tissue sarcomas. When a definitive diagnosis is not achievable, this algorithm will help the radiologist determine the likelihood of benignity, a short differential diagnosis, and a recommendation for any further imaging workup.

Radiographic bone age determination is part of the routine evaluation of suspected growth disorders. Simplicity and low cost are its major advantages but ionizing radiation should be taken into consideration. Conventional ultrasonography (US) has proven effective to identify ossification centers of the hand and wrist between 0 and 24 months of age. It may become an innocuous follow-up tool for patients with growth disorders. We aimed to asses the chronological US emergence of the ossification centers of the hand and wrist in healthy infants between 2 and 4 years of age. Read More

The practice of performing dedicated breast ultrasounds in the pediatric emergency department varies according to institution. In the adult population, breast ultrasounds are commonly interpreted by dedicated breast imagers and/or radiologists appropriately qualified to interpret mammograms. Children's hospitals with dedicated pediatric radiology faculty are less likely to have such individuals on staff. This paper examines the practice of breast ultrasounds ordered in the emergency department throughout a large children's health system. Read More

Ultrasound carries high sensitivity in diagnosing acute appendicitis in pediatric patients and is increasingly being used as the preferred method of diagnosis since it does not use ionizing radiation. Although an enlarged diameter of the appendix and non-compressibility are the primary indicators of appendicitis, they do not have perfect specificity. Therefore, secondary features of appendicitis are crucial in supporting the diagnosis of appendicitis. The most sensitive secondary finding of appendicitis is inflammatory echogenic periappendiceal fat. Other secondary signs of appendicitis are either infrequently present, like wall hyperemia, or entirely nonspecific, like periappendiceal free fluid. Improving diagnostic accuracy of appendicitis with additional secondary supportive signs would be helpful. We have subjectively observed that appendix shape may be a helpful secondary sign of appendicitis, and that in certain cases it forms a C-shape or curved appearance when inflamed. It mimics the appearance of the letter ‘C’ and hence, we termed it, the “C sign.” Retrospective review of 999 ultrasound appendix studies that were conducted in our hospital from January 1, 2022, to March 31, 2022, with 150 sonographically positive acute appendicitis cases, we found 10 patients with the positive C sign and deemed positive by US and pathologically to be acute appendicitis. It seems by observation that this sign is not sensitive but specific when found, for acute appendicitis. One probable explanation for this configuration is loop separation that occurs when the proximal and distal ends of the appendix are separated either by inflamed fat or wall thickening. Herein, we show a few examples of the appendiceal “C-sign”, describe our observations, and suggest its potential use as an additional secondary sign of appendicitis. Read More

The female anatomic equivalent of the male processus vaginalis is the canal of Nuck. The canal is formed from a small peritoneal protuberance from the round ligament that extends through the inguinal ring, into the inguinal canal, and terminates in the labia majora. Obliteration of the canal occurs in a superior to inferior direction and usually completes within the first year of life. Non-closure results in a persistent canal of Nuck. Very rarely herniation of abdominal and pelvic contents into the canal of Nuck can occur, much less commonly in females than in the male equivalent. Hernias can present at any age but are most common in children. Recognition of this entity is especially important in cases of ovarian herniation due to the risk of incarceration.
We will provide a review normal anatomy, potential canal contents, the imaging appearance on ultrasound, CT, as well as MRI, and discuss differential diagnosis using cases of canal of Nuck hernia in 4 patients aged 22 days though 17 years. Read More

Accurate diagnosis of Polycystic Ovary syndrome (PCOS) in adolescents relies on clinical, biochemical and radiographic criteria. The traditionally utilized Rotterdam criteria define polycystic ovarian morphology (PCOM) as the presence of 12 or more follicles, measuring 2-9 mm in either ovary and/or an ovarian volume >10 cm³. Due to advancement in imaging techniques and resolution, it has been proposed by the Androgen Excess Society Taskforce to update criteria for diagnosis of PCOM to presence of 25 or more follicles per ovary. The aim of this study was to correlate the diagnosis of PCOM using ovarian volume and follicle number criteria in adolescents with confirmed PCOS based on NIH criteria. The NIH criteria are stringent and require the presence of both menstrual irregularity and clinical or biochemical evidence of hyperandrogenism for a diagnosis of PCOS. Read More

Congenital portosystemic shunts represent a rare congenital malformation which diverts portal blood to the systemic circulatory system. These malformations can either be intrahepatic or extrahepatic. The intrahepatic portosystemic shunts have been classified into four types. Intrahepatic congenital portosystemic shunts demonstrates a persistent communication between the portal and hepatic venous structures, which were derived from the embryonic vitelline veins or between the vitelline and subcardinal veins. A ductus venosus, a normal structure in neonates, represents an intrahepatic congenital portosystemic shunt between the left portal vein and left hepatic vein. It typically closes between 2-17 days of postnatal life. In our institution, since April 2020, there have been five separate cases of intrahepatic congenital portosystemic shunts in newborns. We will review the imaging for each of these cases, as well as review the current literature and classification of portosystemic shunts. Read More
