[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.

[Testicular echography in torsion and epididymitis. Apropos of 2 cases].

We report two cases, one of a long-standing epididymitis with a testicular infarct, the second of testicular tumor with torsion. Scrotal ultra-sound is a quick, easily applied, accurate method to follow cases of subacute epididymitis with atypical evolution. In case of testicular torsion, secondary to tumor, it helps to rule out scrotal exploration and to decide of an orchidectomy with a high located surgical approach.

[MRI in the diagnosis of lissencephaly. Apropos of a case].

In a patient with clinical manifestations suggestive of brain malformation, CT showed lissencephaly with absent opercularization. The child had seizures but not a typical EEG of hypsarhythmia. MRI confirmed the diagnosis and showed heterotopic grey matter and abnormal basal ganglia. High grey-white matter contrast and the possibility of imaging the brain in sagittal, coronal and transverse planes make MRI the methode of choice for the evaluation of lissencephaly and other brain malformations.

[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.

[Right inguino-pelvic cystic lymphangioma].

We report an unusual case of a pelvic cystic lymphangioma. The first symptom was an inguinal mass which evoked a lymph node. Diagnosis was suspected thanks to CT. Surgery confirmed the diagnosis. It is an unusual aspect of a malformation which is itself not frequent.

[Idiopathic laryngotracheobronchial calcifications in children. Apropos of 2 cases].

Calcifications of cartilage in the larynx, trachea and bronchi are rare in children. Two cases reported and listed with 5 similar cases of the literature. Such calcifications are generally discovered in young children and congenital stridor is commonly associated with. Calcifications of bronchi are not present in every case. The blood calcium is normal. Laryngoscopic examination shows in two cases a laryngeal stiffness. The prognosis is good. In two cases, one of the parents of under 40 years old, also had calcifications of the trachea and of the bronchi.

Localised form of spondylo-epiphyseal dysplasia congenita.

We report an unusual case of spondylo-epiphyseal dysplasia congenita which affected only the hips and the thoraco-lumbar spine. The epiphysis of the long bones are normal apart from the hips. Our child has a bilateral epiphyseal dysplasia of both proximal femoral epiphysis discovered incidentally at 11 months and confirmed later on at 8 years, associated with abnormalities of the superior margin of the vertebral bodies from T11 to L2. Very few similar cases have been reported anteriorly.

About one case of vertebral chondroblastoma.

The authors report the case of a 9-year-old child which suffered from a chondroblastoma of the cervical spine. He had clinical signs of superior mediastinum compression with inflammation of the respiratory upper air-way. Surgery was performed. Diagnosis was established by the pathologist. The recurrence one year later was treated again by surgery and also by radiotherapy. Another recurrence four years later was fatal. The difficulties of the diagnosis and the appearance of recurrences in some cases of chondroblastoma are reviewed in the literature.
