The diagnostic value of magnetic resonance imaging compared to computed tomography in the evaluation of fat-containing thoracic lesions.

Intrathoracic fat-containing lesions may arise in the mediastinum, lungs, pleura, or chest wall. While CT can be helpful in the detection and diagnosis of these lesions, it can only do so if the lesions contain scopic fat. Furthermore, because CT cannot demonstrate microscopic or intravoxel fat, it can fail to identify and diagnose microscopic fat-containing lesions.

Consensus statement on thoracic radiology terminology in Portuguese used in Brazil and in Portugal.

Effective communication among members of medical teams is an important factor for early and appropriate diagnosis. The terminology used in radiology reports appears in this context as an important link between radiologists and other members of the medical team. Therefore, heterogeneity in the use of terms in reports is an important but little discussed issue.

Tomographic findings in bronchial atresia.

Objective: To evaluate computed tomography (CT) findings in 23 patients with bronchial atresia.

Materials And Methods: The CT images were reviewed by two radiologists who reached decisions by consensus. We included only patients who presented with abnormalities on CT and in whom the diagnosis had been confirmed by pathological examination of the surgical specimen (if the lesion was resected).

Saccular Superior Vena Cava Aneurysm: Case Report and Comprehensive Review.

Saccular superior vena cava aneurysms (SVCAs) are one of the rarest causes of mediastinal masses. Seventy years after the first published case report, to the best of our knowledge, fewer than 30 cases have been described in the literature. This article provides an overview of the peculiarities regarding diagnosis and treatment performed in these cases and addresses the protocol adopted in our case report.

Lymphocytic interstitial pneumonia: computed tomography findings in 36 patients.

Objective: To analyze the computed tomography (CT) findings of lymphocytic interstitial pneumonia (LIP).

Materials And Methods: We retrospectively reviewed the clinical and CT findings of 36 patients with LIP, including 25 women and 11 men, with a mean age of 52.5 years (age range, 22-78 years).

Superior vena cava aneurysm: an unusual mediastinal mass.

Superior vena cava aneurysms are rare mediastinal vascular lesions. Aneurysms are classified as fusiform and saccular, with the latter being rarer than the former. We report the case of an asymptomatic 75-year-old woman who presented with a superior mediastinal mass.

Neurofibromatosis type 1: State-of-the-art review with emphasis on pulmonary involvement.

Neurofibromatosis type 1 (NF-1), also known as von Recklinghausen's disease, is an autosomal dominant dysplasia of the ectoderm and mesoderm with a variable clinical expression, but near-complete penetrance before the age of 5 years. The estimated incidence is 1 in 3000 births. NF-1 is characterized by collections of neurofibromas, café-au-lait spots, axillary and inguinal freckling, and pigmented hamartomas in the iris (Lisch nodules).

CT-guided Transthoracic Core-Needle Biopsies of Mediastinal and Lung Lesions in 235 Consecutive Patients: Factors Affecting the Risks of Complications and Occurrence of a Final Diagnosis of Malignancy.

Objective: To assess the impact of patient-, lesion- and procedure-related factors on the risks of complications and final diagnosis of malignancy in PCNB of mediastinal and lung lesions.

Material And Methods: We studied a large single-center cohort of 235 consecutive patients (66.8% men; 58.

Tomographic aspects of penetrating thoracic trauma: injuries from firearms and other weapons.

Objective: The aim of this study was to analyze the various computed tomography findings in penetrating chest trauma, as well as to determine the frequency and extent of the lesions.

Material And Methods: We studied the computed tomography findings from 40 cases of penetrating thoracic trauma, of which 35 (85.8%) were gunshot wounds and 5 (14.

"Pulmonary Vein Sign" for Pulmonary Embolism Diagnosis in Computed Tomography Angiography.

Purposes: Considering that pulmonary arterial obstruction decreases venous flow, we hypothesized that filling defects in pulmonary veins can be identified in areas adjacent to pulmonary embolism (PE). This sign was named the "pulmonary vein sign" (PVS), and we evaluated its prevalence and performance for PE diagnosis in computed tomography pulmonary angiography (CTPA).

Methods: This retrospective study enrolled consecutive patients with clinical suspicion of PE who underwent CTPA scan.

Metastatic pulmonary calcification: high-resolution computed tomography findings in 23 cases.

Objective: The aim of this study was to evaluate the high-resolution computed tomography (HRCT) findings in patients diagnosed with metastatic pulmonary calcification (MPC).

Materials And Methods: We retrospectively reviewed the HRCT findings from 23 cases of MPC [14 men, 9 women; mean age, 54.3 (range, 26-89) years].

High-resolution computed tomography findings in eight patients with hantavirus pulmonary syndrome.

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.
