    Notes: Conclusions La référence aux coupes anatomiques doit permettre d'éviter les deux principaux écueils de la tomographie des glandes surrénales, à savoir le caractère incomplet de l'exploration et les difficultés d'interprétation de l'imagerie obtenue. Elle fait apparaître une indiscutable asymétrie entre les deux glandes qui s'exprime à la fois sur le plan morphologique et topographique et une situation moins profonde que ne le laisserait supposer la simple anatomie descriptive de ces organes en place.

    Description / Table of Contents: Résumé Les auteurs ont étudié les modifications morphologiques de l'a. poplitée lors de la flexion du genou. L'étude radio-anatomique comporte l'analyse d'artériographies de profil pour différents degrés de flexion articulaire, puis des dissections pour objectiver les structures anatomiques en cause dans l'adaptation morphologique de l'a. poplitée au mouvement articulaire. Chez 5 sujets volontaires, non athéromateux, 15 séquences angiographiques en I.R.M. ont été réalisées au niveau des genoux en position d'extension et de flexion. Les artériographies et l'angio-I.R.M. montrent qu'au fur et à mesure que le degré de flexion articulaire augmente, des flexuosités apparaissent au niveau de l'a. poplitée haute supra-articulaire alors que les parties moyenne et basse de l'a. poplitée gardent une courbure harmonieuse, s'écartant du plan postérieur de l'articulation. Les dissections semblent montrer que cette adaptation artérielle se fait entre deux points fixes, l'un proximal : le canal des adducteurs, l'autre distal : l'origine de l'a. tibiale antérieure. L'angio-I.R.M. paraît une voie d'avenir dans l'exploration des vaisseaux des membres. L'opposition comportementale des différents segments de l'a. poplitée permet de mieux comprendre la physiopathologie des traumatismes et des malpositions de l'axe artériel poplité.
    Notes: Summary We studied the morphological modifications of the popliteal artery during knee flexion. An anatomical, radiological study consisted of analysis of lateral arteriographs in different degrees in joint flexion followed by dissection to reveal the anatomical structures involved in the morphological adaptation of the popliteal artery to joint movement. In five non-atheromatous volunteers, 15 MRI angiographic sequences were done at the level of the knee in extension and flexion. The arteriographs and angio MRI showed that as joint flexion increased tortuosities appeared in the supra-articular upper popliteal artery while the middle and lower parts of the popliteal artery kept an even curve retracted from the posteriror surface of the joint. Dissection seemed to show that this arterial adaptation occurred between two fixed points, one proximal (the adductor canal) and the other distal (the origin of the anterior tibial artery). Angio MRI seems to be a future route for the assessment of the limb vessels. The contrasting behaviour of the different segments of the popliteal artery allows us to understand better the pathophysiology of trauma and malpositions of the popliteal arterial trunk.

    Notes: Abstract The authors report 17 cases of a right non-recurrent inferior laryngeal n. (NRILN) observed during 15 years of practice of thyroid and parathyroid surgery. In their last two cases, the existence of an aberrant right subclavian a., constantly associated with NRILN, was confirmed by MRI angiography. On the basis of the literature and their own experience, the authors review the incidence of this double anomaly, its embryologic explanation and its anatomic and surgical importance. They stress the diagnostic factors and the therapeutic implications, very different in children and adults, of a particular vascular anomaly whose outcome is little understood.

    Description / Table of Contents: Résumé Les auteurs rapportent 17 cas de non recurrence du nerf laryngé inferieur droit, observés en 15 ans de pratique de la chirurgie thyroidienne et parathyroidienne. Dans les deux dernières observations, l'existence d'une artère subclavière droite aberrante — ou arteria lusoria, constamment associée à l'anomalie nerveuse, a pu être confirmée par une angioIRM. S'appuyant sur la revue de la littérature et sur leur expérience personnelle, les auteurs rappellent la fréquence de cette double anomalie, son explication embryologique et son interêt anatomique et chirurgical. Ils insistent sur les circonstances diagnostiques et les conséquences thérapeutiques, très différentes chez l'enfant et chez l'adulte, d'une anomalie notamment vasculaire dont on connait mal les complications évolutives.

    Notes: Abstract A 23-year-old man presented with a 2-week history of intracranial hypertension. CT showed a large, nonenhancing cerebellar mass with surrounding calcification and displacement of the fourth ventricle. MRI revealed a septate lesion, with low signal on T1-weighted and high signal on T2-weighted images. The cerebellar tonsils were displaced below the foramen magnum and there was associated syringomyelia. The MRI features were characteristic of Lhermitte-Duclos (LD) disease (dysplastic gangliocytoma) and the diagnosis was confirmed following surgery. In this case, we emphasise the usefulness of MRI in the diagnosis of LD disease and consider the possible pathogenesis of the associated syringomyelia.

    Notes: Abstract Sonography appears highly sensitive in characterizing the severity of gastroesophageal reflux, screening the infants at risk of esophagitis. Sonography is also useful in evaluating efficacy of treatment. In our experience reflux is only damaging if constantly repeated and related to severe hiatal dysfunction. Ultrasound (US) is a good alternative for the assessment of hiatal function and gives furthermore indispensable morphological data.
