A baby with two lower cervical tracheoesophageal fistulas was evaluated with a barium esophagram and computerized tomography (CT). The esophagram identified both fistulas. Axial CT demonstrated the esophageal attachment of the upper fistula and completely displayed the lower fistula. A change in caliber of the esophagus from a collapsed to a distended state marked the site of the fistulas.

Angiography of azygos continuation of inferior vena cava in situs ambiguus with left isomerism (polysplenia syndrome).
We have in our records 11 patients with situs ambiguus and left isomerism (polysplenia). Ten had an interruption of the inferior vena cava (IVC) with azygos continuation; in eight cases the continuation was to the left superior vena cava (LSVC), in one case to the right superior vena cava (RSVC) and in one case to both the LSVC and RSVC. ⋯ The angiographic confirmation of the azygos system anatomy is important in planning the surgical correction of patients with left isomerism. Clinically, given the same heart defects with normal pressures, the right-sided drainage is probably more favorable, producing less peripheral desaturation.

Case ReportsHypoxic/ischaemic cerebral injury in the neonatal brain. A report of sonographic features with computed tomographic correlation.
Ultrasound has been used in 11 neonates whose history or clinical features suggested the possibility of hypoxic/ischaemic lesions. The ultrasound findings were correlated with computed tomographic findings in nine infants and with pathological findings in two. On ultrasound scan, areas of increased echoes represented both hypoxic/ischaemic and haemorrhagic lesions. ⋯ Computed tomography failed to clearly demonstrate the cystic changes. Three types of lesions, viz. diffuse, focal and periventricular were based on the location of brain injury, the former two occurring in term infants and the latter in premature infants. Ultrasound has been shown to be of value for definition of the site and extent of hypoxic/ischaemic cerebral lesions in the newborn and for observation of their evolution.

Case ReportsPolyarteritis nodosa: regression of arterial aneurysms following immunosuppressive and corticosteroid therapy.
Angiographic illustration of aneurysmal involvement of renal, hepatic, and splenic arteries in a 10-year-old boy, led to correct diagnosis of polyarteritis nodosa. A follow-up study one year after cyclophosphamide and prednisone therapy showed near complete resolution of the arterial lesions and a marked improvement of renal blood flow.

Case ReportsBronchial rupture in children following blunt chest trauma. Report of five cases with emphasis on radiologic findings.
We present five patients with fracture of the bronchus, in whom the diagnosis of bronchial rupture was first suggested because of persistent leakage of air, atelectasis of a segment of the lung or of the entire lung, mediastinal and deep cervical emphysema. In all patients the bronchoscopy was essential to confirm the diagnosis and to determine the full extent of injury.
