Persisting perfusion defects after bronchoscopic removal or spontaneous expulsion of aspirated foreign objects.

Follow-up lung scans were obtained in 9 children to determine whether perfusion lung scanning could be used to verify completeness of foreign-body removal. In 4 patients, extensive perfusion defects were present 4-19 days after removal of the object. In 1 patient, the area of hypoperfusion was larger than the territory served by a persistently obstructed lobar bronchus. Follow-up lung scans are of limited value for verifying completeness of foreign-body removal and localization of retained fragments.

Cavitating lung nodules and pneumothorax in children with metastatic Wilms' tumor.

Lung metastases evolved into large thin-walled cysts in two children with Wilms' tumor. Histologic examination of one lesion suggested that invasion of a small bronchus or bronchiole, leading to ball-valve obstruction, was responsible. One patient also experienced recurrent pneumothorax, probably on the same basis. The formation of thin-walled cysts has not previously been observed with metastatic Wilms' tumor. Pneumothorax is a rare complication of metastatic Wilms' tumor.

Frontometaphyseal dysplasia: evidence for autosomal dominant inheritance.

Frontometaphyseal dysplasia is a syndrome that encompasses cranial hyperostosis, abnormal tubulation of cylindrical bones, and other skeletal and extraskeletal abnormalities. The most striking features are overgrowth of the supraorbital ridges which results in a Mephistophelian facial appearance and a radiographic configuration of the skull that has been likened to a soldier's helmet. Most patients have severe hearing loss, defective dentition, poorly developed musculature, and joint contractures. Dominant inheritance has been suggested in previous reports, but an appropriate pedigree has been documented in only one family. This paper describes three additional patients in two unrelated families: (1) an 8-year-old boy whose mother has mild metaphyseal dysplasia and several minor skeletal abnormalities that have occurred in patients with the syndrome; and (2) two maternal half-brothers. These cases provide additional evidence that frontometaphyseal dysplasia is an autosomal dominant trait with variable penetrance.

Absence and retention of small bowel gas in infants with midgut volvulus: mechanisms and significance.

The radiographic pattern of high intestinal obstruction--gastric and duodenal distension with absence of small bowel gas (ASBG) or a completely gasless abdomen--may be present in infants with midgut volvulus. In most instances, ASBG is associated with viable small bowel. However, when associated with abdominal distension and tenderness ASBG usually reflects strangulated midgut volvulus and bowel necrosis. In some patients with midgut volvulus there is a radiographic pattern of low small bowel obstruction; this is generally associated with necrotic bowel. These seemingly opposite observations can be explained by reviewing the dynamics of gas absorption in normal bowel and in closed loop intestinal obstruction. Impaired blood supply can result in either gaslessness or gaseous distension under differing conditions. Key words: Infant, intestinal tract, intestinal gas, intestinal obstruction, intestinal volvulus, malrotation, gasless abdomen.

Mediastinal esophageal duplication cyst associated with a partial pericardial defect.

A two-year-old girl with a mediastinal esophageal duplication cyst is the twelfth example of a thoracic cyst of foregut origin or pulmonary "sequestration" (bronchopulmonary foregut malformation according to the expanded definition of Gerle et al.) that has been associated with a partial pericardial defect on the same side, suggesting that anomalous thoracic masses of several morphologic types have a similar pathogenesis.

Retention of small foreign objects in the stomach and duodenum. A sign of partial obstruction caused by duodenal anomalies.

Small round, oval, or cuboidal foreign objects nearly always pass through the gastrointestinal tract promptly, and stasis of such objects in the stomach or duodenum is extremely uncommon. The authors describe 3 cases of prolonged retention in children with no clinical or plain-film evidence of duodenal obstruction. In each case, a barium meal demonstrated a congenital anomaly of the duodenum producing partial obstruction: duodenal stenosis, prolapse of the duodenal diaphragm ("windsock duodenum"), and an annular pancreas.

Sonographic diagnosis of fetal hydrops.

Sonograms obtained during the 32nd and 34th weeks of a pregnancy complicated by severe Rh isoimmunization demonstrated features diagnostic of fetal-hydrops-scalp and body wall edema, ascites, hepatosplenomegaly and placental enlargement. The earliest sign that can be detected sonographically is placental enlargement.

Congenital oesophageal strictures due to cartilaginous rings.

Two cases of distal oesophageal stricture secondary to tracheo-bronchial remnants containing cartilage are presented. The clinical histories and radiographic appearances of these lesions are discussed as is the postulated embryogenesis. A characteristic finding, when present, is the linear collection of barium projecting horizontally from the area of stricture, representing respiratory epithelial ducts.

Chronic eosinophilic pneumonia in a one-year-old child.

Although the literature well describes chronic eosinophilic pneumonia in the adult, there are no reports of this entity in the pediatric age group. We describe a child with chronic eosinophilic pneumonia, emphasizing the specific radiologic features, common conditions in the differential diagnosis, and dramatic response in corticosteroid administration, which is a unique feature of this entity.

"Rectal ears".

"Rectal ears," transitory protrusions of the rectum into the internal inguinal rings, were observed in a 16-month-old girl who also had "bladder ears." Inguinal hernias were not present. The etiology and significance of "rectal ears" has not been determined.
