    Description / Table of Contents: Résumé Les ligaments de la cheville sont superficiels et aisément accessibles à l'échographie. Par contre, la fiabilité de cette technique pour l'étude de ces ligaments n'a, à notre connaissance, jamais été validée. Dans ce but, dix chevilles firent l'objet d'une corrélation écho-anatomique. Les cinq faisceaux ligamentaires principaux (trois sur le versant latéral et deux sur le versant médial) ont mesurés à l'échographie et les valeurs été vérifiées après dissection. Cette étude montre que les ligaments de la cheville peuvent être analysés en échographie et que les mesures effectuées sont valables et d'une précision de l'ordre de 2 mm pour le faisceau antérieur et le faisceau moyen du plan ligamentaire latéral. L'échographie paraît donc, par sa simplicité et son faible prix, constituer en élément important du bilan ligamentaire et de la gravité des entorses de la cheville.
    Notes: Summary The ligaments of the ankle are superficial and easily accessible at ultrasonography. Suprisingly, the reliability of this technique has never been proven. With this goal in mind, ten ankles were subjected to a ultrasono-anatomic comparison. The five principle ligamentous fascicles (three on the lateral side and two on the medial side) measured at ultrasonography and the values verified after dissection. This study shows that the ligaments of the ankle are analyzed with ultrasonography and that the measures done are valid and have a precision of 2 mm for the anterior fascicle and the lateral fascicle of the lateral ligamentous plane Due to its simplicity and its low price, ultrasonography appears to be an important method in evaluating the ligaments and the degree of seriousness of ankle sprains.

    Atypical aspects of intrathoracic posttransplantation lymphoproliferative disorders (1995)

    Notes: Abstract Posttransplant lymphoproliferative disorders (PTLD), developing after immunosuppressive therapy in human organ-graft recipients, are, for the most part, Epstein-Barr virus-induced. The earlier the diagnosis is made, the greater the potential for reversibility. The chest radiographs and CT scans of 10 patients with thoracic locations of PTLD were reviewed. Mediastinal (n = 3) and hilar adenopathy (n = 2), pulmonary nodules (n = 8), and pleural thickening or effusion (n = 4) were encountered. The incidence of partial resolution with clinical remission (n = 4) appears to be noteworthy, and in all likelihood is related to the extensive necrosis (n = 5) that is frequently seen. Slow regression, transitory deterioration in one case, and localization only on the graft side in two cases, were observed. These morphological and evolutionary peculiarities must be known in order to optimize the diagnosis, and thus the prognosis, of these very original disorders.

    Congenital anomalies of tracheobronchial branching patterns: spiral CT aspects in adults (1998)
    Springer

    Notes: Abstract. Congenital abnormalities of the bronchi have been classically described with chest X-rays, conventional tomography, bronchography, CT and MR imaging. Recently, the capacity of spiral CT to explore a complete volume with no gap and excellent multiplanar reformations has been emphasized. The contribution of this technique to the analysis of congenital anomalies of tracheobronchial branching patterns encountered in adult patients is illustrated. Agenesis, aplasia, and hypoplasia are discussed, followed by bronchial atresia and abnormalities of bronchial divisions. In most cases spiral CT permits a full and correct evaluation of the malformation as well as its associated anomalies. It appears therefore to be the preferable technique for studying such anomalies of the tracheobronchial tree. Moreover, knowledge of CT aspects of the main congenital bronchial abnormalities along with complete visualization of the tracheobronchial tree will probably lead to detection of more incidental anomalies.

    Regional distribution of gas and tissue in acute respiratory distress syndrome. I. Consequences for lung morphology (2000)

    Notes: Abstract Objective: To compare the computed tomographic (CT) analysis of the distribution of gas and tissue in the lungs of patients with ARDS with that in healthy volunteers. Design: Prospective study over a 53-month period.¶Setting: Fourteen-bed surgical intensive care unit of a university hospital. Patients and participants: Seventy-one consecutive patients with early ARDS and 11 healthy volunteers. Measurements and results: A lung CT was performed at end-expiration in patients with ARDS (at zero PEEP) and healthy volunteers. In patients with ARDS, end-expiratory lung volume (gas + tissue) and functional residual capacity (FRC) were reduced by 17 % and 58 % respectively, and an excess lung tissue of 701 ± 321 ml was observed. The loss of gas was more pronounced in the lower than in the upper lobes. The lower lobes of 27 % of the patients were characterized by “compression atelectasis,” defined as a massive loss of aeration with no concomitant excess in lung tissue, and “inflammatory atelectasis,” defined as a massive loss of aeration associated with an excess lung tissue, was observed in 73 % of the patients. Three groups of patients were differentiated according to the appearance of their CT: 23 % had diffuse attenuations evenly distributed in the two lungs, 36 % had lobar attenuations predominating in the lower lobes, and 41 % had patchy attenuations unevenly distributed in the two lungs. The three groups were similar regarding excess lung tissue in the upper and lower lobes and reduction in FRC in the lower lobes. In contrast, the FRC of the upper lobes was markedly lower in patients with diffuse or patchy attenuations than in healthy volunteers or patients with lobar attenuations. Conclusions: These results demonstrate that striking differences in lung morphology, corresponding to different distributions of gas within the lungs, are observed in patients whose respiratory condition fulfills the definition criteria of ARDS.

    Perirenal textiloma: MR and serial CT appearance (1998)

    Notes: Abstract. We describe changes in imaging features of a textiloma (retained surgical sponge or retained foreign body) left in the renal fossa after exploratory renal surgery. One year after the initial surgery, the MR aspect of the textiloma was not specific, with a homogeneous low signal intensity on T1-weighted images. Serial CT examinations over 4 years demonstrated progressive growth and calcification of the mass which appeared pseudocystic with a peripheral inflammatory wall. Granulomas caused by a retained surgical sponge should be considered as a cause of retroperitoneal mass in patients with a history of prior surgery.
