Gadoxetate disodium (Gd-EOB-DTPA) is a relatively new hepatobiliary MRI contrast agent. It is increasingly used in adults to characterize hepatic masses, but there is little published describing its use in children. The purpose of this paper is to describe our pediatric MRI protocol as well as the imaging appearance of pediatric liver lesions using(More)
To build a common controlled vocabulary is a formidable challenge in medical informatics. Due to vast scale and multiplicity in interpretation of medical data, it is natural to face overlapping terminologies in the process of practicing medical informatics [A. Rector, Clinical terminology: why is it so hard? Methods Inf. Med. 38 (1999) 239-252]. A major(More)

Emerging from its initial designation as a type of unilateral multilocular cyst, cystic nephroma has been considered as either a developmental abnormality or a neoplasm or both. Many have viewed cystic nephroma as the benign end of the pathologic spectrum with(More)
BACKGROUND Microphthalmia transcription factor (MITF)-associated (MiT) tumors are a family of rare malignancies, including alveolar soft part sarcoma (ASPS), clear cell sarcoma (CCS), and translocation-associated renal cell carcinoma (tRCC) that have dysregulated expression of oncogenic MITF family proteins. The MET receptor tyrosine kinase gene is(More)
BACKGROUND Local lymph node involvement in adults with renal cell carcinoma (RCC) is associated with poor outcome. The prognostic significance of local lymph node involvement in children with RCC has not been studied systematically. METHODS A retrospective review of patients treated at St Jude Children's Research Hospital (Memphis, TN) and an extensive(More)
Clinical trials in Wilms tumor (WT) have resulted in overall survival rates of greater than 90%. This achievement is especially remarkable because improvements in disease-specific survival have occurred concurrently with a reduction of therapy for large patient subgroups. However, the outcomes for certain patient subgroups, including those with unfavorable(More)
The outcomes of hepatic undifferentiated embryonal sarcoma (HUES) have historically been limited by persistent, unresectable disease and the subsequent development of disease resistance and dissemination. We present our institutional experience with HUES and assess current treatment trends and outcomes in the era of liver transplantation. We conducted a(More)
