The many faces of neuroblastoma.
Neuroblastoma is a common tumor in childhood. It arises in the adrenal gland or in various extraadrenal primary sites of the sympathetic chain. Clinically, it may present as an abdominal mass or as disseminated metastatic disease. We studied 52 patients with neuroblastoma, and the typical and unusual radiographic features of the disease are presented.

Use of low osmolar contrast for gastrointestinal studies in low-birth-weight infants.
Metrizamide is a safe, water-soluble contrast medium suitable for bedside gastrointestinal studies in low-birth-weight infants. We describe our experience with 26 patients and 34 examinations. We present illustrative cases and indicate the clinical applications. Similar results are anticipated when less expensive nonionic contrast agents are approved by the Food and Drug Administration for pediatric use.
Computerized tomography demonstration of an intrarenal teratoma.
The computerized tomographic appearance of an intrarenal teratoma is described. The differential diagnoses, especially from Wilms tumor, are discussed.
Digital subtraction angiography in children.
Preliminary results with digital subtraction angiography in infants and children have shown this to be an excellent screening procedure and often diagnostic. The examination can be performed satisfactorily on outpatients. Sixty patients have undergone this examination for evaluation of suspected abnormalities of the aortic arch and its branches, intracranial arteries, pulmonary arteries, abdominal aorta and its branches, and peripheral vessels. Adequate sedation is mandatory to prevent motion artifacts. While the literature reports increasing use of central venous catheters for delivery of contrast material, the use of short catheters placed in an antecubital vein is satisfactory for the pediatric patient. Techniques of the procedures are described along with seven appropriate case examples.
Computed tomography in the evaluation of chest lesions in the pediatric patient.
The role of computed tomography (CT) in the management of chest masses in the pediatric patient is emphasized and illustrated. Thirty-seven patients with various chest lesions who had both CT and conventional radiologic evaluations are reviewed. CT was the most consistently accurate examination, especially in the evaluation of disease extent and relationship with other organs. CT was the only modality to provide clinically useful information in 27% of the cases, and it provided significant additional information in another 24% of the group.
Radiologic considerations of intensive care in the premature infant. Annual oration in honor of William Henry Neil, M.D., 1924-1972.
Radiology of the premature infant is a relatively new specialty in medicine. Most complications of intensive care in the premature infant are radiologically recognizable, and therefore are frequently first detected by the radiologist. Complications of umbilical catheterization and of pulmonary and cardiovascular systems, alimentary tract, skeletal system, and central nervous system are considered. Radiation exposure and cost of intensive care are also discussed.

Bowel stenosis as a late complication of acute necrotizing enterocolitis.
Bowel stricture as a late complication of acute necrotizing enterocolitis in 10 neonates is discussed with respect to time interval to development, number of strictures, location, sexual and racial distribution and possible contributing factors. This is compared with previous reports in the literature. Differences in the distribution of acute and late sites of involvement are discussed.

Tuberous sclerosis: a case report with aortic aneurysm and unusual rib changes.
An unusual case of tuberous sclerosis with thick sclerotic ribs, thoracic and abdominal aortic aneurysms and sacrococcygeal chordoma is described. The patient has been followed for 17 years and the radiographic features of the ribs and especially the aortic aneurysms are unusual features of this condition.
