Liposarcomas are rare mesenchymal tumors that usually develop in lower extremities or retroperitoneum; cervico-mediastinal presentation is quite uncommon. These neoplasms are commonly diagnosed at a late stage because they remain asymptomatic until nearby structures are compressed. This makes radical excision particularly challenging. To date, alternative chemoradiotherapy protocols have not yet been standardized. We report a case of a 55-year-old man with a right laterocervical mass and without substantial symptoms...

The goal of this study was to extract features from radial deviation and radial gradient maps which were derived from thoracic CT scans of patients diagnosed with lung adenocarcinoma and assess whether these features are associated with overall survival. We used two independent cohorts from different institutions for training (n= 61) and test (n= 47) and focused our analyses on features that were non-redundant and highly reproducible. To reduce the number of features and covariates into a single parsimonious model, a backward elimination approach was applied...

I Cases Susarte, A Sánchez González, J M Plasencia Martínez
Chest radiography for pneumothorax screening is a frequently employed test. However, there is some controversy about which radiographic technique to choose. Posteroanterior chest radiography taken during expiration has been the technique used for many decades because several experts in classical thoracic radiology, such as Greene and Felson, recommended it. However, chest radiography, with posteroanterior and lateral projections, taken during deep breath is the appropriated technique to initially assess the whole thoracic pathology...

INTRODUCTION: Pulmonary neuroendocrine cells (PNEC) are present in the normal lungs with the incidence of 1 in 2500 epithelial cells. They usually proliferate in the presence of reactive processes related to inflammation and fibrosis of the lung parenchyma. The division of pulmonary neuroendocrine cell hyperplasia proposed by Travis et al. additionally distinguished diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) or proliferation that occurs in people without reactive hyperplasia risk factors...

Isolated aneurysms of the iliac arteries are rare. The diagnoses of these aneurysms become easier with non-invasive radiologic investigations. The development of endovascular treatment is a recent alternative to surgical treatment. We report our experience in the management of 8 cases of isolated iliac aneurysms in the department of cardiovascular and thoracic surgery of the Habib Bourguiba Hospital of Sfax.

Temminck's ground pangolin is the only pangolin present in South Africa. It is a myrmecophagous mammal with a bipedal gait. The thoracic limbs are used to break open ant nests, dig for food and expand previously occupied burrows. This study describes the osteology and radiological anatomy of the thoracic limbs of this threatened species. Thoracic limbs from four Temminck's ground pangolins, which succumbed from electrocution or natural causes, were digitally radiographed in situ. The individual bones were then cleaned, described and digitally radiographed...

Sarcoidosis is a multisystem chronic inflammatory disease of unknown etiology characterized by widespread growth of non-caseating granulomas. The diagnosis of sarcoidosis is based on clinical and imaging presentation, histologic confirmation and the absence of alternative diseases. Radiology and Nuclear Medicine play an essential role in the diagnostic work-up of patients with sarcoidosis to assess disease extent and activity. In addition, imaging modalities have shown their potential in managing these patients in terms of treatment response and prognostic assessment...

Optimizing radiologists' performance is a major priority for managers of health services/systems, since the radiologists' reporting activity imposes a severe constraint on radiology productivity. Despite that, methods to optimize radiologists' reporting workplace layout are scarce in the literature. This study was performed in the Radiology Division (RD) of an 850-bed University-based general hospital. The analysis of the reporting workplace layout was carried out using the systematic layout planning (SLP) method, in association with cluster analysis as a complementary tool in early stages of SLP...

By nature, idiopathic interstitial pneumonias, have been diagnosed in a multidisciplinary manner. As classifications have been subject to significant refinement over the last decade, the importance of correlating clinical, radiologic, and pathologic information in order to arrive at a diagnosis, which will predict prognosis in any given patient, has become increasingly recognized. In 2013, the American Thoracic Society and European Respiratory Society updated the idiopathic interstitial pneumonias classification scheme, addressing the most recent updates in the field...

Hypophosphatasia (HPP) is an autosomal recessive metabolic disorder with impaired bone mineralization due to mutations in the ALPL gene. The genotype-phenotype correlation of this disorder has been widely described. Here, we present two affected siblings, whose fetal phenotypes were discordant. A 31-year-old Japanese woman, G0P0, was referred to our institution because of fetal micromelia. After obstetric counseling, the pregnancy was terminated at 21 weeks' gestation. Post-mortem radiographs demonstrated severely defective mineralization of the skeleton...
