right atrial dilation due to left heart disease is a common complication among adults. the present review aimed to describe a case of massively dilated right atrium in a female patient presenting with valvular heart disease and no atrial fibrillation. the results of chest x-ray revealed a large opacity filling the lower right hemithorax, falsely interpreted as a mediastinal mass. during the tra...
normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 there are a few case series of giant cell tumor (gct) in the spine and sacrum. gct in the thoracic vertebrae is even more exceptional in the medical literature. in this article we report a gct in a 25-year-old male who presented with progressive back pain and dyspnea. on contrast-enhanced multidetector computer tomography,...
Background: It is well known that, at the time of the initial presentation of patients with non-small cell lung cancer, N-status is very important in accurate staging and avoiding inappropriate surgical procedures. Also, if mediastinal lymph node metastasis (N2) of non-small cell lung cancer (stage IIIA) is present, neoadjuvant (preoperative) chemora-diotherapy is indicated therefore a quick an...
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...
Background: Mediastinum includes the vital organs like the heart the major respiratory passages and the major vessels due to this vicinity, the masses of this area with malignant or benign etiology or cause systemic diseases such as metastatic malignancies or granulomatous reactions can be potentially fatal. Materials and Methods: According to the priority of the problem, a ten years comprehens...
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...
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%), ...
