Abstract
Objective: The purpose of this study was to describe the high-resolution computed
tomography (HRCT) findings in patients with hantavirus pulmonary syndrome
(HPS). Materials and Methods: We retrospectively reviewed HRCT findings from eight cases of HPS. All
patients were men, aged 19-70 (mean, 41.7) years. Diagnoses were established
by serological test (enzyme-linked immunosorbent assay) in all patients. Two
chest radiologists analyzed the images and reached decisions by
consensus. Results: The predominant HRCT findings were ground-glass opacities (GGOs) and smooth
inter- and intralobular septal thickening, found in all eight cases;
however, the crazy-paving pattern was found in only three cases. Pleural
effusion and peribronchovascular thickening were observed in five patients.
The abnormalities were bilateral in all patients. Conclusion: The predominant HRCT findings in patients with HPS were GGOs and smooth
inter- and intralobular septal thickening, which probably correlate with the
histopathologic findings of pulmonary edema.

Abstract
OBJECTIVE To investigate bronchiectasis variations in different computed tomography (CT) respiratory phases, and their correlation with pulmonary function test (PFT) data, in adults. METHODS Retrospective data analysis from 63 patients with bronchiectasis according to CT criteria selected from the institution database and for whom PFT data were also available. Bronchiectasis diameter was measured on inspiratory and expiratory phases. Its area and matched airway-vessel ratios in both phases were also calculated. Finally, PFT results were compared with radiological measurements. RESULTS Bronchiectatic airways were larger on inspiration than on expiration (mean cross-sectional area, 69.44 vs. 40.84 mm2; p < 0.05) as were airway-vessel ratios (2.1 vs. 1.4; p < 0.05). Cystic bronchiectasis cases showed the least variation in cross-sectional area (48%). Mean predicted values of forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC) were 81.5 and 77.2%, respectively, in the group in which bronchiectasis could not be identified on expiratory images, and 58.3 and 56.0%, respectively, in the other group (p < 0.05). Variation in bronchiectasis area was associated with poorer lung function (r = 0.32). CONCLUSION Bronchiectasis detection, diameter, and area varied significantly according to CT respiratory phase, with non-reducible bronchiectasis showing greater lung function impairment.

Abstract
Objective This study aimed to compare two self-expanding stents, a nitinol stent and an
elgiloy stent, both placed percutaneously, in terms of their efficacy in
palliating inoperable malignant biliary obstruction. Materials and Methods We retrospectively investigated 99 patients with unresectable malignant
biliary obstruction treated with percutaneous placement of a self-expanding
metallic stent at our institution between May 2007 and January 2010. Serum
bilirubin and liver enzyme levels were measured before and 30 days after
stenting. For all procedures using elgiloy or nitinol stents, stent
occlusion and patient survival rates were calculated using Kaplan-Meyer
analysis. Results All of the patients showed clinical improvement after stent placement, with
no difference between the two groups. In both groups, the occlusion-free
survival rate was 67% at 30 days, 37% at 90 days, 25% at 180 days, and 10%
at 360 days, with no significant difference in relation to the type of
stent. Conclusion The two stents evaluated showed comparable efficacy for the percutaneous
treatment of unresectable biliary malignancy, with good clinical
results.

Abstract
Cancer is the leading cause of natural death in the pediatric populations of developed countries, yet cure rates are greater than 70% when a cancer is diagnosed in its early stages. Recent advances in magnetic resonance imaging methods have markedly improved diagnostic and therapeutic approaches, while avoiding the risks of ionizing radiation that are associated with most conventional radiological methods, such as computed tomography and positron emission tomography/computed tomography. The advent of whole-body magnetic resonance imaging in association with the development of metabolic- and function-based techniques has led to the use of whole-body magnetic resonance imaging for the screening, diagnosis, staging, response assessment, and post-therapeutic follow-up of children with solid sporadic tumours or those with related genetic syndromes. Here, the advantages, techniques, indications, and limitations of whole-body magnetic resonance imaging in the management of pediatric oncology patients are presented.

Abstract
Tuberous sclerosis complex (TSC) is a genetically determined hamartomatous
neurocutaneous disease with high phenotypic variability. TSC is characterized by
widespread hamartomas and benign, or rarely malignant, neoplasms distributed in
several organs throughout the body, especially in the brain, skin, retina,
kidney, heart, and lung. Common manifestations include cortical tubers,
subependymal nodules, white matter abnormalities, retinal abnormalities, cardiac
rhabdomyoma, lymphangioleiomyomatosis, renal angiomyolipoma, and skin lesions.
The wide range of organs affected by the disease implies that TSC1 and TSC2
genes play important roles in the regulation of cell proliferation and
differentiation. Although recent advances in treatment have improved morbidity,
the prognosis remains quite poor and nearly 40% of patients die by the age of 35
years. Imaging is important in the evaluation of TSC because of its role not
only in presumptive diagnosis, but also in defining the full extent of
involvement. This information allows a better understanding of the behavioural
phenotype, as related to lesion location. Imaging also contributes to treatment
planning. This pictorial review describes common and uncommon imaging
manifestations of TSC.

Abstract
To evaluate the performance of magnetic resonance imaging (MRI) compared to computed tomography (CT) in patients diagnosed with pulmonary mycosis. We prospectively included 21 patients diagnosed with pulmonary mycosis between January 2013 and October 2014. Inclusion criteria were presence of respiratory symptoms, histopathological diagnosis of mycosis and absence of mycosis treatment. Reviewers identified one predominant imaging pattern per patient: nodular, reticular or airspace pattern. Afterwards, all CT findings were analysed separately per lobe and compared to MRI. Nodular pattern was the most common found (CT: 76.20%; MRI: 80.96%), followed by airspace pattern (CT and MRI: 9.52%) and reticular (CT: 9.52%; MRI: 4.76%). Compared to CT, MRI performance varied according to radiological finding and pulmonary region. For nodules, MRI presented high sensitivity (100% [95% CI: 93.52-100]) and specificity (100% [95% CI: 92.00-100]). For bronchiectasis and septal thickening, there were poorer positive predictive values (33.33% [95% CI: 1.77-87.47]; and 83.33% [95% CI: 50.88-97.06] respectively). As specificity and negative predictive value had superior results than sensitivity and positive predictive value, rather than for diagnosis of this condition, MRI might be more considered for the follow-up of patients with pulmonary mycosis, an alternative to multiple radiation exposures with CT follow-up.
