Idiopathic pleuroparenchymal fibroelastosis (IPPFE) is a rare disorder recently included in rare idiopathic interstitial pneumonias according to the updated American Thoracic Society/European Respiratory Society classification. IPPFE is characterized by pleural and subpleural parenchymal fibrosis causing volume loss predominantly in the upper lung lobes. Age of onset is variable, IPPFE mainly occurs in third and fourth decades. We present a 16 year old patient with a 2-year history of exertional dyspnea, nonproductive cough and weight loss...

Introduction: Staging investigations at diagnosis are customary to accurately assign a clinical stage before therapy. The practice of routine imaging in patients asymptomatic for metastasis is not recommended but widely adopted. This study was done to reexamine the basis behind guideline recommendations and to identify the factors predictive of asymptomatic metastasis. Methods: Oncology records of 200 breast cancer patients in clinical Stages I-III at diagnosis were prospectively reviewed...

Pulmonary artery aneurysms (PAA) and pseudoaneurysms (PAP) are caused by infections, vasculitis, trauma, pulmonary hypertension, congenital heart disease, and connective tissue disease. Most cases of such aneurysm occur in the trunk or major branches of the pulmonary artery, while the peripheral type is less common. The treatment modalities are medical therapy, surgery, and percutaneous catheter embolization. The mortality rate associated with rupture is approximately 50%. We encountered a case of a 53-year-old man with a pulmonary artery pseudoaneurysm secondary to pneumonia and cavity formation during chemotherapy for acute myeloid leukemia (AML)...

BACKGROUND: Scapular fractures have been traditionally taught to be associated with significant injuries and major morbidity. As we demonstrated with sternal fracture, pulmonary contusion and rib fracture, increased chest CT utilization and head-to-pelvis CT (pan-scan) protocols in blunt trauma evaluation, however, may diagnose minor, clinically irrelevant scapular fractures, possibly rendering previous teachings obsolete. OBJECTIVES: To determine the 1) percentages of scapular fractures seen on chest CT only (SOCTO) versus seen on both CXR and CT and of isolated scapular fracture (scapular fracture without other thoracic injuries), 2) frequencies of associated thoracic injury with scapular fracture, and 3) proportion of patients admitted, mortality, hospital length of stay, and injury severity scores (ISS), comparing four patient groups: scapular fracture, non-scapular fracture, scapular fracture SOCTO, and isolated scapular fracture...

A previously healthy 21-year old man presented to the emergency department with sudden onset central chest pain exacerbated by breathing. A plain chest X-ray showed air within the mediastinum and pericardium confirmed by a CT scan with contrast. The patient history did not raise suspicion of any concomitant disease and the diagnosis of spontaneous pneumomediastinum with pneumopericardium was made. The patient recovered completely over the next few days with bed rest and analgesics. Spontaneous pneumomediastinum is an uncommon disease caused by rupture of perivascular alveoli causing air leakage to the mediastinum...

We sought to determine if vertebral trabecular attenuation values measured on routine body CT scans obtained for a variety of unrelated indications can predict future osteoporotic fractures at multiple skeletal sites. For this HIPAA-compliant and IRB-approved retrospective cohort study, trabecular attenuation of the first lumbar vertebra was measured in 1966 consecutive older adults who underwent chest and/or abdominal CT at a single institution over the course of one year. New pathologic fragility fractures that occurred after a patient's CT study date were identified through an electronic health record database query using ICD-9 codes for vertebral, hip, and extremity fractures...

Background: The current standard methods for detecting pulmonary artery diseases are pulmonary artery enhanced computed tomography (CT) scan and pulmonary arteriography. However, some patients cannot tolerate these procedures for various reasons. The present study aimed to investigate the feasibility and operation process of endobronchial ultrasound (EBUS) in exploring the pulmonary artery. Methods: Based on normal contrast-enhanced chest CT images, the sites and process for exploring the pulmonary arteries were established...

The internal thoracic artery (ITA) is the largest thoracic wall artery and is clinically important primarily for use in coronary artery bypass grafting. A number of anatomic variants of the ITA have been reported; however, bilateral, aberrant lateral branches of the ITA never have. The importance of this finding lies in the positioning of the artery at a potential chest tube insertion site. Here, we report the identification, on CT scan, of this rare variation in a young male trauma patient.

BACKGROUND: EAST guidelines suggest tube thoracostomy (TT) be considered for all traumatic hemothoraces. However, previous research has suggested that some traumatic hemothoraces may be observed safely. We sought to 1) determine the safety of selective observation for traumatic hemothorax, and 2) identify predictors of failed observation. METHODS: All patients with traumatic hemothorax from 2000-2014 at a Level I Trauma Center were identified and categorized by size as small (<300cc) or large (≥300cc) based on chest CT-scan measurements...
