[Eosinophilic granuloma of bones in children].

Eosinophilic granuloma of bone or Langerhans cell histiocytosis is mostly unifocal. It appears on plain X Ray as a solitary destructive lesion of long bones or flat bones. CT is useful to define the extension to the cortical bone and also to precisely localize the lesion when the anatomy is complex (hip, spine, base of the skull). MR is very useful in case of more aggressive lesions when there is extension to soft tissues. Differential diagnosis includes circumscribed osteitis and tumors in the case of extensive destruction. The natural course of solitary lesions is favorable, spontaneously or with therapy. The prognosis is more serious in the case of multiple lesions.

[Imaging of bronchogenic cysts in children].

The authors report a retrospective series of 22 cases of bronchogenic cysts in children. The development of antenatal ultrasonography allowed the diagnosis in 3 cases. When the diagnosis is suggested for the time first postnatally, chest x-ray and oesophagography remain the essential initial investigations. Thoracic ultrasonography needs to be developed, as in some cases it can reveal the cystic nature of the tumour. In difficult cases, the work-up should be completed by CT scan, while keeping in mind that not all bronchogenic cysts present in the form of low-density images. A detailed review of the literature shows that mediastino-pulmonary opacities are more frequent than exclusively pulmonary images in the form of hyperlucent, fluid level or solid opacity images.

Osteoid osteoma of the rib: a case report.

A case of a 6-year-old boy with a painful dorsal scoliosis secondary to an osteoid osteoma in a rib is described. Surgical excision was performed and the scoliosis decreased. Such cases are very rare.

[Striated osteopathy].

Striated osteopathy, a roentgenological entity characterized by longitudinal striations, can occur concomitantly with a number of disorders which should be routinely looked for. There are three types of striated osteopathy. The pure form without severe bone disorders is the form originally reported by Voorhoeve. In the second form, there is a concomitant fibrous dysplasia, such as Jaffe-Lichtenstein-Uehlinger disease, Ollier enchondromatosis, sponastrism dysplasia, or osteopetrosis. This group also includes bone dysplasias with sclerosis such as melorheostosis, osteopecilia, and sclerosis of the base of the skull which is sometimes seen in patients with striated osteopathy. In the third form, striated osteopathy occurs concomitantly with a skin disease such as patchy dermal hypoplasia or hyperpigmented skin lesions.

[Cholelithiasis in childhood].

Ultrasound examination of the abdomen permits us to diagnose in childhood much more bile duct calculi than before. Surgery is not necessary in all cases but a follow-up with ultrasound is usefull.

[Peptic esophagitis and scoliosis in children].

Four pediatric cases of peptic esophagitis in patients with severe dorsolumbar scoliosis including three with a history of neurological disease provide the opportunity to point out that curvature of the spine fairly often causes development of gastroesophageal reflux. By displacing the anchoring points of the stomach and stretching the lower esophageal sphincter, scoliosis can be responsible for malposition of the cardia and fundus and for gastroesophageal reflux. Furthermore, plaster corsets increase intraabdominal pressure and may therefore promote gastroesophageal reflux.

[Separation of the distal humeral epiphysis in young children. Radiologic features].

Separation of the distal humeral epiphysis is infrequent in young children. Diagnosis is difficult since the entire condylar region is almost completely composed of cartilage. Marked sequelae occur if the diagnosis is not promptly made and arthrography is required to evaluate the extent of lesions. Two cases in children aged 2 1/2 years and one day are reported.

[Tillaux's fracture].

Tillaux fracture or fracture of the antero-lateral portion of the distal tibia has a vertical fracture line either at the middle of the epiphysis or close to the external malleolus. It is seen around 13-14 years. Distance from the fracture line to the external malleolus depends of the degree of closure of the epiphyseal plate. When the medial aspect of the physis is open, the fracture line is more medial. The location of the fracture line in the epiphysis therefore depends on the maturity of the physis as shown by closure of its medial portion. Tomography is frequently necessary to see the fracture line and mainly to appreciate the fracture gap. If the gap is less than two millimeters non operative treatment with plaster cast is sufficient.

[X-ray computed tomography and MRI in Krabbe's disease].

Krabbe's disease whose CT appearance is well known should benefit of the development of MRI as this method is more accurate. MRI permits early diagnosis of leucodystrophy. Yet it must be emphasized that abnormal white matter patterns are not sufficient to permit the diagnosis of Krabbe disease. In the case reported atrophy of the brain, the cerebellum and the brain-stem, demyelination of the white matter and necrosis of corpus callosum were observed. The abnormalities of the brain on MRI pictures help in the diagnosis as they may alert clinicians to the possibility of Krabbe disease in infants with progressive encephalopathy. A definitive diagnosis can be established thanks to the laboratory tests.

[Contribution of MRI to the diagnosis of double aortic arch].

The authors present a case of double aortic arch explored by MRI and discuss the advantages and disadvantages of MRI as compared to other noninvasive imaging methods, such as ultrasounds and digital angiography, in congenital pathology of the aorta. Because it provides good quality images, can explore the aorta in all three dimensions, has optimal vascular contrast without contrast injection and carries no risk, MRI is indispensable in all cases where ultrasonography finds its limitations. Besides, the subjective factor inherent in the operator is very small, and MRI is the best available method to study the relations between the aorta and the surrounding organs; this is particularly important in case of double aortic arch owing to compression of the neighbouring organs with, notably, stridor. However, the vascular map is less accurate than with angiography, and the cost, the problem of access to the machines and the long time required for acquisitions limit the use of MRI.
