Contribution of computed tomography in the aetiology and prognosis of cerebral palsy in children.

Retrospective analysis of computed tomographic (CT) examinations in 76 children with cerebral palsy without any severe intellectual handicap has revealed abnormalities in 63% of these children; abnormalities were present in 88% of former pre-term infants. This study highlights the significant pathogenic role of periventricular leucomalacia in cerebral palsy, since in 45% of the cases of this series this diagnosis had been reached as a result of a characteristic CT appearance associated with a history of premature birth and very specific clinical deficits. The CT abnormalities, mostly posterior and generally bilateral and symmetrical, affect the contours of the lateral ventricles, which become straight and angular, and often involve ventriculomegaly (85%). Localized juxtaventricular hypodensities were only found in a few cases (6%). The cognitive and intellectual sequelae in these children were more severe than in those children whose CT examination was normal, and were also more pronounced when the longitudinal fissure of the cerebrum was enlarged.

Sonographic hepatic arterialisation in newborns receiving parenteral nutrition.

Two cases of severe liver disease with portal hypertension in the newborn are reported. Such complications occurred after necrotizing enterocolitis requiring total parenteral nutrition and digestive exclusion for a long time. Ultrasonography showed an hepatic arterialisation with portal hypertension.

[Malignant bone tumors in children. Is there still a role for arteriography?].

The authors have studied retrospectively 32 children with malignant bone tumor. All patients underwent conventional arteriography just before surgery. Distal foci of hypervascularisation and venous thrombosis, not seen at CT, may alter surgical treatment. When large extension to soft tissues is present, the arteriography remains unchallenged to evaluate the venous involvement.

[Diagnostic difficulties of isolated symptomatic unilamellar periosteal appositions. Uncommon form of fatigue fracture in children].

We describe five cases of painful periosteal reaction occurring in children. The initial radiographic appearance of stress fracture may be troublesome since the new bone formation may be confused with malignant bone lesion. Because of the importance of making a correct diagnosis multiple imaging techniques will often be employed. We discuss the radiographic signs and their usefulness in the differential diagnostic of periosteal reaction.

[A radio-endoscopic case: Barrett esophagus in children].

The authors report a case of Barrett's oesophagus in a child. This observation is characterized by the extent of the lesion which is of three types of metaplasic epithelium usually seen in this disease (fundic, cardial and intestinal tissue); the difficulties in differential diagnosis from uncomplicated hiatal hernia justify radiological and endoscopical examinations with multiple biopsies. The discussion centers on the risk of malignant transformation with its therapeutical consequences and the long term follow-up of such patients.

[Post-traumatic arthritis of the wrist caused by an intra-articular foreign body].

The authors report the case of a 12 year-old child presenting with post-traumatic arthritis of the wrist with intra-articular metallic foreign bodies. The trauma was initially considered to be benign, not operated on and forgotten by the child and its family. Excision of a synovial granuloma was followed by a favorable outcome.

[Radiologic approach to endocrine pathology in childhood].

The new imaging techniques (ultrasound, CT, digital subtraction angiography) have greatly modified the diagnostic approach to the endocrinopathies in pediatric age, notably if of surgical interest. The main clinical indications to the ultrasound and/or CT study of hypophysis, thyroid, adrenals and female internal genital tract are synthesized in this paper. A diagnostic flow-chart is also suggested for each clinical entity.
