Although Tuberculosis (TB) is very common in early childhood, we see an increased incidence of TB in adolescents due to increased susceptibility. It is also important to note that adolescent TB affects those living in low/middle income countries where TB is very common. There is a paucity of literature regarding the sequelae of TB disease in adolescents based on advanced cross-sectional imaging. We aimed to review the imaging features seen on CT imaging of the chest post adolescent TB in a cohort of patients from Peru. 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

The incidence of e-cigarette, or vaping, product use associated lung injury (EVALI) has been increasing since the summer of 2019. At least seven distinct patterns of lung injury have been described with this emerging disease (1). A recent report from the United States Centers for Disease Control and Prevention indicates that approximately 15% of patients diagnosed with EVALI have been in the pediatric age group (2). Because of the potential legal and social repercussions of vaping and cannabis use, pediatric patients may be disinclined to admit to use of electronic cigarettes. As such, recognition of the potential imaging patterns of this disease may allow the pediatric radiologist to raise the possibility of EVALI to facilitate timely diagnosis and appropriate management of the disease.

This educational exhibit will review the imaging findings seen in the various patterns of lung injury identified with this increasingly common lung disease. We will also discuss the indications for obtaining imaging studies in patients with suspected EVALI. In addition, we will describe the potential clinical presentations in these patients.

Cancer is the most common cause of disease-related mortality for adolescent patients, 13-19 years of age. Primary liver neoplasms are relatively uncommon entities in this population accounting for 0.5-2.0% of all neoplasms as per the current literature. The most common primary liver malignancy in adolescent patients is hepatoblastoma, which accounts for approximately two thirds of liver tumors. Benign tumors of the liver in the adolescent population include adenomas, focal nodular hyperplasia, hamartomas, and vascular tumors. Hepatic neoplasms in adolescent patients are typically not detected clinically until they reach a large size. While there are many exceptions, these patients generally have normal liver function as well as normal growth and development. In this case series, we examine the imaging characteristics across multiple modalities of several large primary hepatic neoplasms in the adolescent population encompassing both benign and malignant as well as common and uncommon entities. We will also review how the underlying pathophysiology of these neoplasms relates to their imaging appearances. Cross-sectional imaging with MRI or CT, similar to evaluation in adult patients, is considered the best method of evaluating the character and extent of hepatic masses. However, initial workup usually includes plain film x-ray or ultrasound. Benign and malignant hepatic neoplasms in the adolescent population share many similar radiographic features, and therefore, knowledge of these entities and their imaging appearances is essential in order to develop an appropriate differential diagnosis.

There is significant variation in the approach to diagnosing PCOS (polycystic ovarian syndrome), particularly in adolescents. PCOS, more recently referred to as hyperandrogenic anovulation, is a classic tried of oligomenorrhea and/or anovulation, hirsutism, and obesity. The Rotterdam criteria are widely used in the adult population, with diagnostic criteria including 2 of the following 3: ovulatory dysfunction, clinical and/or biochemical signs of hyperandrogenism, polycystic ovarian morphology on ultrasound. Although it is acknowledged that ultrasound is not necessary for diagnosing PCOS in adults if the first 2 criteria are met, there is sufficient controversy in adolescent literature that classic morphologic appearance in addition to one other criterion may not be diagnostic.
Polycystic ovarian morphology (PCOM), the imaging correlate typically associated with the clinical diagnosis of PCOS, can be a normal finding in adolescents. Given that the criteria for the polycystic ovarian morphology (PCOM) remains controversial, it is important for a pediatric radiologist to understand the significance of PCOM in adolescents, and how radiology can best and most significantly add to the clinical picture.
This presentation will provide a review of consensus guidelines for PCOS and PCOM, and best practices of describing findings of PCOM in adolescents. Novel approaches will also be discussed, including ongoing research in follicle counts and stromal volume with 3D ultrasound. Read More
