The extrapleural space (EPS) is an anatomic space at the periphery of the chest that can be involved in a number of disease processes. This space lies between the inner surface of the ribs and the parietal pleura and contains adipose tissue, loose connective tissue, lymph nodes, vessels, endothoracic fascia, and the innermost intercostal muscle. It is often overlooked on cross-sectional imaging studies and almost invariably overlooked on conventional radiographic studies. At conventional radiography, the EPS occasionally can be seen when there is extrapleural fat proliferation, which might be confused with pleural thickening or pleural effusion...

We are reporting a case of fatal radiation pneumonitis that developed six months following chemoradiation for limited stage small cell lung cancer. The patient was a 67-year-old man with a past medical history of Hashimoto's thyroiditis and remote suspicion for CREST, neither of which were active in the years leading up to treatment. He received 6600 cGy delivered in 200 cGy daily fractions via intensity modulated radiation therapy with concurrent cisplatin/etoposide followed by additional chemotherapy with dose-reduced cisplatin/etoposide and carboplatin/etoposide and then received prophylactic cranial irradiation...

We herein report two cases of malignant pleural mesothelioma with marked lymphangiosis. The patients included a 68-year-old man and a 67-year-old man who both had a history of exposure to asbestos. Computed tomography (CT) on admission showed pleural effusion with pleural thickening. In both cases, a histopathological examination of the pleura confirmed the diagnosis of epithelioid malignant mesothelioma. They received chemotherapy, but the treatment was only palliative. The chest CT assessments during admission revealed marked pleural effusion and mediastinal lymphadenopathy...

Esophageal metastasis from colorectal carcinoma is uncommon, and diagnosis of esophageal metastasis is difficult. We report a case of a 54-year-old woman with postoperative recurrence of rectal cancer metastasizing to the esophagus. She underwent rectectomy and adjuvant chemotherapy with fluorouracil, leucovorin plus oxaliplatin for stage IIIB rectal cancer. Three years later, she presented with dysphagia and cough. Computed tomography showed thickening of the esophagus wall, enlargement of the lymph nodes in the mediastinum and abdomen, and ground-glass opacities in the right lung...

The purpose of this study was to clarify the recognizable computed tomography (CT) features of small cell lung carcinoma (SCLC).Contrast enhanced CT scans were reviewed retrospectively for mass location, mediastinal extension, and other concomitant findings in 142 patients with pathologically proven SCLC. SCLC was classified into hilar mass only (type I), hilar mass with ipsilateral mediastinal extension (type II), hilar mass with bilateral mediastinal extension (type III), and peripheral mass (type IV). When mediastinal lymphadenopathy (m-LAP) was indistinguishable from a hilar mass, we defined it as a mediastinal conglomerate mass (m-CM)...

BACKGROUND: Bronchoalveolar lavage (BAL) has gained acceptance for diagnosis of Interstitial lung disease (ILD). The advent of high-resolution computed tomography (HRCT) has reduced the clinical utility of BAL. This work has utilized the recommendations of the American Thoracic Society (ATS) to optimize BAL and the findings have been associated with clinical examination and HRCT to precisely narrow down the cause of ILD. MATERIALS AND METHODS: BAL was performed on ILD suspects at the target site chosen based on HRCT...

Diffuse pulmonary lymphangiomatosis (DPL) is a rare lymphatic disorder characterized by uncontrolled proliferation of lymphatic vessels. Histologically benign, however, it can lead to death because of its progression. In this paper, we would like to present an unusual case of diffuse pulmonary lymphangiomatosis involving a 28-year-old young female who was suffered chest pain and polypnea for one year, and also a lot of chylous effusion in left chest. Lymphoma and lymphangitic metastasis was the primary diagnosis in other hospitals...

BACKGROUND: Pulmonary metastasectomy has come to be recognized as an effective treatment for selected patients with some malignancies. On the other hand, the role of pulmonary metastasectomy for gastric cancer is still unknown. Metastasectomy is rarely indicated in cases of pulmonary metastasis from gastric cancer, because in most cases, the metastasis occurs in the form of lymphangitic carcinomatosis and the lesions are numerous. The purpose of this study was to determine the surgical outcomes and prognostic factors for survival after pulmonary metastasectomy...

A 58 year old male with a history of cirrhosis (hepatitis B and C), a long smoking history, and a recently diagnosed high-grade transitional cell carcinoma of the bladder wall presented three days after a biopsy procedure with abdominal pain, nausea, and new hypoxemia on room air. The chest radiograph was clear and the CT angiogram showed only a borderline large pulmonary artery, two small nodules (3mm and 4mm) in the right middle lobe of the lung, and emphysematous changes throughout the lung parenchyma. There was no evidence of pulmonary embolism...

This study was designed to compare the primary patterns of metastases and clinical outcomes between adenocarcinoma (Adenoca) and squamous cell carcinoma (SQ) in initially diagnosed stage IV non-small cell lung cancer (NSCLC).Between June 2007 and June 2013, a total of 427 eligible patients were analyzed. These patients were histologically confirmed as Adenoca or SQ and underwent systemic imaging studies, including 18F-fluorodeoxyglucose positron emission tomography/computed tomography and brain imaging. Synchronous metastatic sites were categorized into 7 areas, and whole-body metastatic scores were calculated from 1 to 7 by summation of each involved region...

An elderly woman with a history of pulmonary tuberculosis reportedly diagnosed and treated 30 years prior to presentation was found unresponsive at home. Chest imaging revealed innumerable pulmonary nodules worrisome for an infectious process, specifically tuberculosis. The patient deteriorated rapidly and in accordance with her wishes, aggressive interventions were withheld. She died within 48 h from respiratory failure. A limited chest autopsy was performed and revealed the cause of death as lymphangitic spread of cancer from a primary lung adenocarcinoma...

BACKGROUND: Pathologic features of end-stage pulmonary sarcoidosis (ESPS) are not well defined; anecdotal reports have suggested that ESPS may mimic usual interstitial pneumonia (UIP). We hypothesized that ESPS has distinct histologic features. METHODS: Twelve patients who received a diagnosis of pulmonary sarcoidosis and underwent lung transplantation were included. Control subjects were 10 age- and sex-matched lung transplant patients with UIP. Hematoxylin and eosin-stained tissue sections were examined for the following features: extent/pattern of fibrosis; presence and quantity (per 10 high-power fields) of fibroblast foci and granulomas; distribution and morphology of granulomas; and presence and extent of honeycomb change...

A case of angiosarcoma of the heart with predominant involvement of the pericardium and diffuse bilateral lymphangitic spread to both lungs is presented. The patient was a 32-year-old man admitted for cough, dyspnea, and intermittent hemoptysis. Chest x-ray and computed tomography scans revealed bilateral pulmonary infiltrates and pericardial effusion. An echocardiogram showed a large oval mass overlying and compressing the right atrium and ventricle. At autopsy, multiple hemorrhagic tumor nodules were present in the pericardial sac, and an 8-cm hemorrhagic tumor mass was found overlying and compressing the right atrial appendage and infiltrating the heart muscle...

Pulmonary lymphangitic carcinomatosis (PLC) is the diffuse infltration of lymphatic systems by adenocarcinomas. Because of its vague clinical symptoms and absence of malignant features, confrmatory diagnosis requires transbronchial or open-lung biopsy. Tumor spread is postulated to occur by means of retrograde lymphatic permeation with tumor growth along the lymphatic channels and involvement of vascular endothelial growth factor-C in a signaling pathway. The authors describe the case of a 45-year-old woman whose presentation with cough and dyspnea led to diagnosis of pulmonary lymphangitic carcinomatosis with superimposed pulmonary hypertension, tumor thrombotic microangiopathy, and ultimately metastatic signet ring cell gastric adenocarcinoma...
