Children with symptomatic ileocolic or ileo-ileocolic intussusceptions can be successfully managed in one of a number of different ways. The nonoperative enema reduction technique has major advantages over surgical reduction and high success rates can be achieved using pneumatic or hydrostatic reduction techniques under fluoroscopic or sonographic guidance.(More)
A variety of pediatric renal masses may be differentiated from Wilms tumor on the basis of their clinical and imaging features. Wilms tumor is distinguished by vascular invasion and displacement of structures and is bilateral in approximately 10% of cases. Nephroblastomatosis occurs most often in neonates and is characterized by multiple bilateral(More)
The vast majority of symptomatic intussusceptions in children arise in the ileum and are either ileocolic or ileoileocolic. The clinical diagnosis of these "idiopathic" intussusceptions may be difficult to make. Failure to make a prompt diagnosis and initiate appropriate treatment may lead to bowel ischemia, perforation, peritonitis, shock and even death.(More)
Objective. To review the imaging appearances, management and outcome of a large number of children with intussusception owing to pathologic lead points (PLP) in an attempt to define the role of various imaging modalities in this clinical setting.¶Materials and methods. Review of the records and imaging studies of 43 children with intussusception due to PLP(More)
Ultrasonography (US) is of value in the evaluation and characterization of breast masses in children. Most masses represent either normal breast tissue, cysts, or fibroadenomas. Premature thelarche may be unilateral, and normal breast tissue is found at US. Cysts are commonly retroareolar; when they become infected, they appear sonographically as a complex(More)
Background. To analyze the spectrum of clinical features, management and outcome of children with documented spontaneous reduction of intussusception (SROI).¶Materials and methods. Review of records of 50 children (33 boys, ¶17 girls; age range 11 days–15 years; mean age 4 years) with documented SROI, in whom intussusception was initially diagnosed by(More)
In the previous two parts of this review on intussusception, the diagnosis and management of symptomatic, "idiopathic" ileocolic and ileoileocolic intussusceptions, which are considered to result from hyperplasia of lymphoid tissue in the distal ileum, were discussed. In this third part, those intussusceptions with an identifiable cause including pathologic(More)
A wide spectrum of entities may give rise to soft-tissue masses in children, including benign and malignant tumors, pseudotumors, and both neoplastic and nonneoplastic vascular lesions. Because of its excellent tissue contrast, multiplanar capability, and lack of ionizing radiation, magnetic resonance (MR) imaging has become the modality of choice in the(More)
Bone marrow transplantation is frequently performed to restore hematologic and immunologic competence after chemotherapy and radiation therapy for a range of childhood malignancies, as well as to treat various congenital conditions in which hematologic and immunologic functions are depressed or absent. Potentially devastating complications may occur during(More)
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)
