Les pneumopathies interstitielles diffuses chroniques: un mariage de raison entre pathologiste, clinicien et radiologue [Diffuse parenchymal lung disease, multidisciplinary approach and role of pathology]

The diagnostic approach to diffuse parenchymal lung disease (DPLD) and especially to the idiopathic interstitial pneumonias has changed over the last two decades, mostly thanks to the development of high resolution CT. Though far from replacing pathology, this additional tool has contributed to the definition of new and more precise diagnostic criteria especially for idiopathic interstitial pneumonias, integrating data provided by the three main contributors: lung specialist, radiologist and pathologist. The purpose of this article is to review the role of histopathology in the multidisciplinary approach of the diagnosis of DPLD and idiopathic interstitial pneumonias

Is tomography of intervertebral disc calcification useful in children?

In the past ten years, we have found cervical intervertebral disc calcifications in three children on plain films of the cervical spine made because of cervical pain. In each case, we required further radiological investigations, antero-posterior and lateral linear tomography for two children and an axial computed tomography for one child. In each case, tomography revealed no supplementary useful information. On retrospect, we think that these examinations caused unnecessary irradiation and that they should only be carried out in the rare circumstances when disc calcification is associated with neurological symptoms

Linear opacities on HRCT in bronchiolitis obliterans organising pneumonia.

The aim of this study was to report the high-resolution computed tomography (HRCT) appearances of linear opacities that may occur in isolation or in combination with other changes in bronchiolitis obliterans organising pneumonia (BOOP). Eleven patients with BOOP and linear opacities on HRCT were identified at three independent teaching hospitals. The HRCT images and clinical course of each patient were reviewed. Two distinct types of linear opacity were identified. The type-1 opacity extended in a radial manner along the line of the bronchi towards the pleura and was usually intimately related to bronchi. The type-2 opacity occurred in a sub-pleural location and bore no relationship to the bronchi. Both types occurred most commonly in the lower lobes, frequently were associated with multi-focal areas of consolidation and usually completely resolved with treatment. There was no associated bronchiectasis, irreversible volume loss or a reticular or honeycomb pattern. In 2 patients linear opacities were the sole abnormality on HRCT. Bronchiolitis obliterans organising pneumonia may occur in a pure "linear form" or HRCT may demonstrate linear opacities in addition to multi-focal consolidation

Magnetic resonance imaging of nontraumatic shoulder instability in children.

Nontraumatic shoulder instability is infrequent in children. We examined prospectively with high-field magnetic resonance imaging (MRI) 11 patients with this disorder, including 2 with Holt-Oram syndrome and 11 healthy control subjects. The MR findings in the glenohumeral joint in normally growing children are presented. Two patients with shoulder instability were considered as normal, one presented with type 2 (Zlatkin) labral lesions, three, type 3 and one, type 4 lesions. Close attention to the normal imaging patterns of the maturing glenohumeral joint is required to avoid pitfalls in the interpretation of the images

Nonoperative management of traumatic splenic injuries: is there a role for proximal splenic artery embolization?

OBJECTIVE: The objective of our study was to evaluate our experience with transcatheter proximal (i.e., main) splenic artery embolization (TPSAE) in the nonsurgical management of patients with grade III-V splenic injuries, according to the American Association for the Surgery of Trauma (AAST) guidelines, and patients with splenic injuries associated with CT evidence of active contrast extravasation or blush (or cases meeting both criteria). MATERIALS AND METHODS: The records of patients with traumatic splenic injuries admitted during a 52-month period were retrospectively reviewed for patient age and sex, mechanism of injury, injury severity score (ISS), RBC transfusion requirements, AAST splenic injury CT grade, presence of active contrast extravasation or blush on CT examination, and amount of hemoperitoneum on CT examination. Demographics, CT findings, transfusion requirements, and outcome were compared using the Student's t test or chi-square test in patients undergoing standard nonoperative management and nonoperative management TPSAE-that is, TPSAE followed by nonoperative management. RESULTS: Of the 79 identified patients with splenic trauma, 67 were managed nonoperatively. Thirty-seven patients (28 men, nine women; mean age, 40 years; mean ISS, 28.8) underwent nonoperative management TPSAE and 30 patients (27 men, three women; mean age, 37 years; mean ISS, 25.1) underwent nonoperative management. Age, sex, and ISS were not significantly different between the two groups. TPSAE was always technically feasible. Splenic injuries were significantly more severe in the nonoperative management TPSAE group than in the nonoperative management group with respect to the mean splenic injury AAST CT grade (3.7 vs 2, respectively; p < 0.0001), active contrast extravasation or blush (38% [14/37] vs 3% [1/30], respectively; p = 0.0005), and hemoperitoneum grade (1.6 vs 0.8, respectively; p = 0.0006). Secondary splenectomy rate was lower in the nonoperative management TPSAE group (2.7% [1/37] vs 10% [3/30]). No procedure-related complications were encountered during early and delayed clinical follow-up. CONCLUSION: TPSAE is a feasible and safe adjunct to observation in the nonoperative management of severe traumatic splenic injuries. The secondary splenectomy rate using nonoperative management TPSAE (2.7%) is among the lowest reported despite a selection of severe injuries
