In neonates and children, sonographic examinations of the renal pyramids may depict a spectrum of unique changes in echogenicity due to the effects of physiologic processes or a wide variety of pathologic processes that may affect the collecting ducts or interstitium of the pyramids. Focused sonographic evaluation of the pyramids with high-frequency(More)
Standardized evaluation of all newborns with antenatally recognized hydronephrosis (ANH) at The Hospital for Sick Children (HSC) has included voiding cystourethrography (VCUG). This paper reviews this protocol to determine: (1) the prevalence of vesicoureteral reflux (VUR) in isolated ANH and (2) the value of performing VCUG in cases of mild hydronephrosis,(More)
OBJECTIVE On radiographs of the abdomen and pelvis, phleboliths often have a characteristic radiolucent center that helps to distinguish them from ureteral stones. On unenhanced CT, the distinction between pelvic phleboliths and distal ureteral stones can be problematic. The objective of this study was to compare the appearance of phleboliths on routine(More)
OBJECTIVE To describe the long-term outcomes of pediatric pleural empyema. DESIGN Prospective observational study from October 2008 to October 2011. SETTING Tertiary care children's hospital. PARTICIPANTS Children with pleural empyema (loculations and/or septations identified on radiologic imaging or frank pus on thoracentesis). MAIN OUTCOME(More)
PURPOSE To examine predictors of a false-positive (FP) result on contrast enema (CE) for the diagnosis of Hirschsprung disease (HD). METHODS Retrospective analysis, over a 5-year period (1999-2004), of infants (<6 months of age) with suspected HD undergoing rectal biopsy following abnormalities identified on CE (transition zone [TZ], abnormal rectosigmoid(More)
PURPOSE To evaluate the current practice of and job market for pediatric radiologists in the United States and Canada with a 1998 survey and compare findings with those of surveys from 1980 and 1989. MATERIALS AND METHODS Surveys were mailed to the 728 active members of the Society for Pediatric Radiology. Questions covered professional practice,(More)
Anaplastic sarcoma of kidney (ASK) is a rare neoplasm recently associated with DICER1 mutations. We report a child with germline DICER1 mutation who developed ASK in preexisting septated renal cysts, which were likely cystic nephroma. From age 2.5 to 6 years, sonographic imaging illustrated changes in the size and number of renal cysts, followed at age 8.8(More)
Embryonal rhabdomyosarcoma (ERMS), a soft tissue sarcoma, is one of the most common pediatric cancers. Certain ERMSs are associated with the DICER1 syndrome, a tumor predisposition syndrome caused by germ-line DICER1 mutations. Characteristic somatic mutations have also been identified in DICER1-associated tumor types. These "hotspot" mutations affect the(More)
OBJECTIVE The purpose of this study was to illustrate the spectrum of sonographic findings in testicular torsion in a large series of neonates and infants. These patterns and their evolution have, to our knowledge, not been described previously. CONCLUSION The sonographic appearance of testicular torsion in neonates and infants can be divided into three(More)
OBJECTIVE The purpose of this study was to assess the safety of power injector use in peripheral IV injections for CT examinations of children by measuring the incidence of contrast extravasation and to review the management of extravasation as reported in the literature. SUBJECTS AND METHODS At a tertiary pediatric center, we prospectively collected data(More)
