background: foregut duplication cysts associated with vertebral anomalies are referred to as neurenteric cyst. about 30 cases have been reported in the literature so far. posterior mediastinal neurenteric cysts are very rare and a few studies could be found in the literature even after extensive search. because of rarity we are prompted to present 7 cases of posterior mediastinal neurenteric cy...

Accurate preoperative staging and restaging of mediastinal lymph nodes in patients with non-small cell lung cancer (NSCLC) is of paramount importance. It will guide choices of treatment and determine prognosis and outcome. Over the last years, different techniques have become available. They vary in accuracy and procedure-related morbidity. The Council of the ESTS initiated a workshop on preope...

We describe a direct and accurate method for defining chest radiographic anatomy and use this method to delineate the anatomic composition of the right mediastinal border in an adult population. Intravenous contrast-enhanced computed tomographic scans of the chest and accompanying scout tomograms from 99 adults without previously known or detected cardiopulmonary disease that could potentially ...

OBJECTIVE To study the efficacy and safety of endoscopic ultrasonography-guided fine-needle aspiration in the management of mediastinal diseases in Hong Kong. DESIGN Retrospective review of prospectively collected data. SETTING University teaching hospital, Hong Kong. PATIENTS A total of 125 consecutive patients with various mediastinal and pulmonary lesions that underwent trans-oesophage...

OBJECTIVE To describe a rare case of occult (<1 cm in diameter) medullary thyroid carcinoma (MTC) in a 45-year-old woman, presenting as an asymptomatic mediastinal mass. DESIGN The diagnostic methodology included laboratory measurements of relevant biochemical and hormonal parameters including calcitonin (CT), carcinoembryonic antigen (CEA) and chromogranin A, and imaging techniques including...

objective(s): this study aimed to evaluate the role of pretreatment suvmax and volumetric fdg positron emission tomography (pet) parameters in the differentiation between benign and malignant mediastinal tumors. in addition, we investigated whether pretreatment suvmax and volumetric fdg-pet parameters could distinguish thymomas from thymic carcinomas, and low-risk from high-risk thymomas.method...

We report a case of a multicentric form of Castleman's disease with multiple lymph nodes showing intense FDG uptake on whole body scan mimicking non-Hodgkin's lymphoma. In this report, the patient had multiple cervical, mediastinal, hilar, retroperitoneal and abnormal lymph nodes in the groin. (18)F-fluorodeoxyglucose positron emission tomography/computed tomography was performed before tissue ...

Primary mediastinal sarcomas are aggressive tumors with a very rare incidence. This report describes the case of a 35-year-old male patient who presented with acute symptoms of dyspnoea, facial puffiness, voice-hoarseness, and engorged neck veins. With the clinical picture consistent with the superior vena cava (SVC) syndrome, the patient was investigated with computed tomography of the chest. ...

Objective: To analysis radiographic features of thoracic sarcoidosis for further understanding of the disease. Methods: 42 cases of pulmonar sarcodiosis were proved by histopathology from April 2009 to July 2014, including 13male and 29 female, and their age were from 33 year-old to 75 year-old, with an average of 50 years. All the cases underwent CT scan. Among them, 25 cases received enhanced...

Lung cancer is rare disease in patients under 25 years of age. It typically occurs in older patients with a history of tobacco use. This case concerns a 20-year-old man with no history of tobacco use who complained of several months of cough and lower back pain and an 11.3-kg weight loss. He was treated for pneumonia after a chest radiograph showed total opacification of the right lung. Compute...
