OBJECTIVE Burkitt lymphoma in children can be localized or disseminated and can involve various sites. Our objective is to review the clinical presentation and abdominopelvic imaging findings of Burkitt lymphoma in the pediatric population. CONCLUSION Numerous abdominal and pelvic imaging findings are seen in Burkitt lymphoma affecting the(More)
With the emerging use of ultrasound in the evaluation of children with Crohn disease presenting with acute abdominal symptoms, there is a need to become familiar with the sonographic features of this disease. Our aim is to provide a primer of the characteristic intramural and extramural US findings in children with Crohn disease to serve as a practical and(More)
Intraperitoneal solid tumors are far less common in children than in adults, and the histologic spectrum of neoplasms of the peritoneum and its specialized folds in young patients differs from that in older patients. Localized masses may be caused by inflammatory myofibroblastic tumor, Castleman disease, mesenteric fibromatosis, or other mesenchymal masses.(More)
OBJECTIVE To evaluate the prevalence of sacroiliitis at diagnosis of juvenile spondyloarthritis (SpA) and the accuracy of physical examination and back pain to detect sacroiliitis, using imaging as the reference standard. METHODS We performed a prospective cross-sectional study of 40 children with newly diagnosed juvenile SpA and 14 healthy controls.(More)
OBJECTIVE In adults, gadolinium contrast enhancement does not add incremental value to fluid-sensitive sequences for evaluation of bone marrow edema. This study was undertaken to determine if magnetic resonance imaging (MRI) contrast is necessary to assess lesions consistent with inflammatory sacroiliitis in children. METHODS Patients with clinically(More)
The knee joint is the one of the most common locations for congenital and developmental musculoskeletal abnormalities. Initial imaging of the knee joint should always begin with conventional radiographs. However, evaluation of the bone marrow, cartilaginous, ligamentous, and other soft-tissue components of the knee joint are better characterized with(More)
Although subpleural cysts are known to be associated with Down syndrome, their etiology and prevalence remains unknown. To determine the prevalence of subpleural cysts in children with Down syndrome and the association with prematurity, congenital heart disease (CHD), extracorporeal membrane oxygenation (ECMO), and chronic ventilator support. A review of(More)
Imaging predictors for surgery in children with Crohn disease are lacking. To identify imaging features of the terminal ileum on short-interval bowel ultrasound (US) and MR enterography (MRE) in children with Crohn disease requiring surgical bowel resection and those managed by medical therapy alone. This retrospective study evaluated patients 18 years and(More)
BACKGROUND/PURPOSE Obstructive symptoms in a patient post-Ladd procedure raise the question of recurrent volvulus. Our objective is to determine the incidence and the radiographical evaluation of recurrent volvulus and abdominal complications after a Ladd procedure. METHODS One hundred ninety-five patients who underwent a Ladd procedure for malrotation(More)
Precocious puberty represents a unique diagnostic problem in which imaging plays an important role. Development of secondary sex characteristics may result from inappropriate activation of the hypothalamic-pituitary axis with release of gonadotropin, or from gonadotropin-independent secretion of sex steroids by the adrenal glands or gonads. A variety of(More)
