Mediastinal masses are usually assessed by computer tomography (CT) and magnetic resonance imaging (MRI). Transthoracic ultrasonography (TUS) can also provide useful information concerning prevascular and posterior mediastinal masses abutting the thoracic wall, but is underused for mediastinal pathology. Moreover, it provides a valuable and safe method for guiding interventional procedures in t...

Mediastinal masses are a frequent finding in patients with Hodgkin's disease, and usually represent either mediastinal lymphadenopathy or a diseased thymus gland.1 In some rare patients, however, the mediastinal mass may be due to diffuse thymic hyperplasia2 or benign thymic cysts.3 In each of the 10 reported cases of thymic cysts in Hodgkin's disease, the diagnosis of the thymic cysts was made...

UNLABELLED Background Primary mediastinal large B-cell lymphoma is a rare lymphoma accounting for no more than 3% of all B-cell lymphomas in children and adolescents. However, patients in this young age group with this lymphoma have the shortest event-free survival of patients with any B-cell lymphoma under current standard chemotherapy protocols. Lymphomas with features intermediate between pr...

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...

OBJECTIVE To measure the intra-fraction displacements of the mediastinal metastatic lymph nodes by using four-dimensional CT (4D-CT) in non-small cell lung cancer (NSCLC). MATERIALS AND METHODS Twenty-four patients with NSCLC, who were to be treated by using three dimensional conformal radiation therapy (3D-CRT), underwent a 4D-CT simulation during free breathing. The mediastinal metastatic l...

Mediastinal pseudocysts can pose a diagnostic and therapeutic challenge to the clinician and surgeon. Recognizing their presence and instituting appropriate therapy can reduce morbidity and mortality. This report describes unusual clinical features in a patient presenting with multiple mediastinal pseudocysts due to pancreatic duct leak secondary to pancreatic duct stenosis and an entrapment of...

The purpose of this study was to analyse a correlation among lung cancer morphology, growth type, localisation and pleura as well as mediastinal invasion. Materials and methods. Data on 372 patients have been analysed. Mediastinal invasion was histologically confirmed in 128 (34.4%) patients. Aorta invasion was confirmed in 21 (5.6%), vena cava superior in 11 (2.9%), pericardium in 55 (14.8%), ...

INTRODUCTION Sarcoidosis is a systemic granulomatous disorder thought to be an exaggerated immune response to unknown antigens. It often presents with bilateral mediastinal lymphadenopathy and/or pulmonary infiltrates (1). Sarcoidosis has been found in association with a variety of malignancies, including malignant myeloproliferative disorders (2). To date, only two cases of acute myeloblastic ...

Primary ectopic meningiomas occurring in the mediastinal region are extremely rare. So far, only five cases of primary mediastinal meningioma have been reported in the literatures. The imaging characteristics and the clinicopathological significance of mediastinal psammomatous meningioma have not been detailed. Here, we report the case of a 42-year-old male with primary posterior mediastinal ps...
