Extracranial cribside sonography in infants.

In 29 real-time ultrasonic studies of infants in the intensive care nursery, the technique either accurately diagnosed or led directly to the correct diagnosis in 27 (93%). Twenty-four of these infants had suspected abnormality in the abdomen or pelvis, three had congestive heart failure and bruits, one had respiratory distress and an opacified hemithorax on chest roentgenogram, and one was a child with ambiguous genitalia in whom sonography identified a uterus. We suggest that portable, real-time ultrasonography is an ideal modality with which to study seriously ill infants whose medical condition precludes transport to the radiology department.

Use of computed tomography in pediatric oncology.

Computed tomography (CT) has dramatically changed the imaging of pediatric oncologic disease. CT precisely displays and characterizes cross-sectional anatomic pathology. This provides important information for diagnosing and staging tumors in infants and children. The principles, techniques, and indications for computed tomography in the evaluation of pediatric extracranial tumors are reviewed in this article. Selected applications of computed tomography for pediatric tumors of the mediastinum, chest wall, lung parenchyma, abdomen, pelvis, and extremities are discussed and illustrated.

Localization of the site of urinary tract infections with the bladder washout test.

The data from 100 bladder washout studies on pediatric patients have been analyzed to derive criteria for interpretation of this test and to define the limitations of this procedure in localization of the site of urinary tract infections. Using the bladder washout test, infection of the upper urinary tract is characterized by an abrupt increase in the concentration of bacteria in urinary specimens collected following urinary bladder sterilization. Infection limited to the lower urinary tract is characterized by scant if any bacterial growth in the specimens of urine collected following bladder sterilization. The site of infection may be incorrectly localized to the lower urinary tract or classified as not determined in patients with scant or intermittent renal bacteriuria.

Congenital saccular anterior urethral diverticulum.

Congenital saccular diverticulum is an uncommon abnormality of the anterior urethra in the male. In seven cases (6 infants and an 8-year-old boy) the diverticulum was well demonstrated by voiding cystourethrography and/or retrograde urethrography. In patients with saccular anterior urethral diverticulum, contrast material fills an oval outpouching of the ventral aspect of the anterior urethra. The clinical presentation, unique radiologic appearance, and differential diagnostic considerations are reviewed.

Ultrasonic diagnosis of obstructed renal duplication and ureterocele.

The diagnoses of complete obstruction in a duplicated renal collecting system and ureterocele can be made with a high degree of confidence by ultrasound. Two children presenting with abdominal masses were examined by gray scale ultrasonography which demonstrated large cystic masses dorsal to and displacing the lower pole of the kidney ventrally and laterally. In one patient the dilated ureter terminated in a ureterocele. Ultrasonography is the appropriate imaging modality for this disease process, though it generally becomes the complementary study to excretory urography in the diagnosis of an obstructed duplicated system. The dilated pelvis and ureter can be imaged to ultrasonography even when their presence is only implied on an excretory urogram. Finally, the cystic nature of a ureterocele, as well as its relationship to the ureter and bladder, makes ultrasonography an ideal technic for evaluating this anomaly.

Radiological observations during transpyloric tube feeding in infants of low birth weight. Perforation of the duodenum and variations in normal duodenal anatomy.

Perforation of the duodenum is a serious complication of transpyloric tube feeding in infants of low birth weight. Polyvinyl chloride and (less commonly) silicone tubes have been implicated. Altered radiographic configuration of the tube in the region of the superior or inferior flexure, associated with clinical deterioration, pneumoperitoneum, peritonitis, or a retroperitoneal fistula, is diagnostic of duodenal perforation. The configuration of the tube may vary during uncomplicated transpyloric alimentation and is frequently incompatible with the expected anatomical course. Contrast examination may demonstrate normal anatomy or mobility of the distal duodenal loop as an adaptation to rigidity of the tube. The possibility of perforation appears to be increased at or adjacent to the flexures.

Ultrasonic diagnosis of renal vein thrombosis in neonates.

Ultrasound findings in four neonates with renal vein thrombosis are described. Three of the patients had unilateral involvement and one had bilateral involvement. Gray scale ultrasonograms showed the affected kidney to be enlarged. Either medium level echoes were distributed evenly throughout the kidney, or there were distinct clumps of echoes randomly scattered within the kidney, sometimes surrounding echofree spaces. The ultrasound findings, combined with appropriate clinical findings, should allow diagnosis of renal vein thrombosis without requiring invasive vascular studies.

Pulmonary sarcoidosis in childhood.

Clinical and radiologic characteristics of pulmonary sarcoidosis in 26 children are presented. Initial nonspecific symptomatology and decreased pulmonary function are almost invariably accompanied by radiologic evidence of pulmonary disease. Bilateral hilar lymphadenopathy frequently associated with bilateral paratracheal adenopathy is characteristic. Other mediastinal lymphadenopathy (subcarinal, anterior, and posterior) is sporadically present, and is invariably associated with the more specific bilateral patterns of thoracic adenopathy. Pulmonary parenchymal involvement is common and predominantly appears radiographically as small irregular densities. Pleural effusion, pneumothorax, and cardiomegaly are unusual findings. Extrathoracic radiographic manifestations are uncommon. Lytic lesions of the tubular bones of the hands and feet are rare in childhood.
