E-cigarette, or vaping, product use-associated lung injury in adolescents: a review of imaging features.
There has been a recent increase in recognition of lung disease related to the use of electronic cigarettes (called "vaping"). These patients present with acute respiratory illness following exposure to vaporized cannabis or nicotine products and sometimes require hospitalization and intensive care. We describe the imaging findings of this disease entity in the pediatric population. ⋯ As seen in our teenage population, e-cigarette, or vaping, product use-associated lung injury (EVALI) is characterized by centrilobular ground-glass nodules and ground-glass opacities with subpleural sparing. The imaging findings are most consistent with acute lung injury resulting from toxic inhalation. Because adolescent pediatric patients might not be forthcoming with their history of electronic cigarette use, it is important for the pediatric radiologist to be aware of the imaging patterns of this disease.

Case ReportsImaging diagnosis of epipericardial fat necrosis in children.
Epipericardial fat necrosis is a benign, self-limited entity increasingly recognized as a cause of chest pain in adults. Epipericardial fat necrosis typically presents with acute pleuritic chest pain or abdominal pain and affects otherwise healthy individuals who characteristically have negative physical exams, laboratory tests and other ancillary tests such as electrocardiograms. We report the imaging findings of epipericardial fat necrosis in a 15-year-old boy and additional images of a case in an 8-year-old boy. Pediatric radiologists should be cognizant of this condition to ensure appropriate diagnosis and avoid unnecessary invasive procedures.

The impact of 18F-FDG PET on initial staging and therapy planning of pediatric soft-tissue sarcoma patients.
Soft-tissue sarcomas in children are a histologically heterogenous group of malignant tumors accounting for approximately 7% of childhood cancers. There is a paucity of data on the value of 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) for initial staging and whether PET influenced management of these patients. ⋯ 18F-FDG PET proved to be a valuable tool for precise initial staging of pediatric soft-tissue sarcoma patients, especially in detecting lymph node metastasis, and could be included in their initial work-up. Given the relative rarity and heterogeneity of this group of tumors, additional investigations are required to definitely establish a role for 18F-FDG PET in the initial staging and therapy planning of soft-tissue sarcoma in the pediatric population.
