Based on Siewert classification, adenocarcinomas of the esophagogastric junction (AEGs) have different behaviors of perigastric-mediastinal nodal metastasis. Siewert type I AEGs have higher incidence of mediastinal nodal metastasis than those of type II or III, especially at middle-upper mediastinum. With regard to the necessity of mediastinal lymphadenectomy, theoretically, transthoracic esoph...

Mediastinal ectopic thyroid is a very rare condition, with few reported cases in the literature and no reported cases in Korea. This report describes an asymptomatic 65-year-old man with a right paratracheal mass compressing the superior vena. Additionally, the epidemiology, clinical manifestation, diagnosis, and management of mediastinal ectopic thyroids are discussed. A mediastinal ectopic th...

Although the intrathoracic location is common for hydatid cyst, chest-wall, mediastinal, pericardial, myocardial, fissural and pleural-space locations have been reported. The incidence of mediastinal involvement is 0.1-0.5%. Here in this paper, two cases of mediastinal hydatid cysts are reported. Both of them had anterior mediastinal hydatidosis, while one of the patients had also additional th...

UNLABELLED We evaluated the value of PET using 18F-fluorodeoxyglucose (FDG) and 11C-methionine, individually or in combination, to distinguish malignant from benign tumors and to identify or exclude mediastinal metastases. METHODS Seventeen patients with a tumor in the lung or mediastinum were evaluated with 18F-FDG and 11C-methionine PET. For morphological comparison, we used CT, and all fin...

Lymphangioma IS a congenital malformation of the lymphatic vessels. It usually manifests at birth or before the age of 2 years. The neck is the most common site. Some lymphangiomas grow steadily and may cause airway obstruction, feeding difficulties and cosmetic problems. Recurrent inflammation and sudden haemorrhage are potential life threatening complications especially in cervico-mediastinal...

BACKGROUND The diagnostic and staging approach for the mediastinal lymphadenopathies, with or whithout pulmonary lesions endoscopically visible, is based on transbronchial needle aspiration (TBNA) during fiberoptic bronchoscopy and on mediastinoscopy. One important factor impacting on TBNA sensitivity is the rapid on site cytological examination (ROSE). AIM The aim of this study was to evalua...

Mediastinal paraganglioma is a rare and slow growing neurogenic tumor. Here, we describe a 49-year-old woman with a non-functional posterior mediastinal paraganglioma. Video-assisted thoracoscopic surgery for tumor excision failed due to massive bleeding. The tumor was excised successfully by lateral thoracotomy with bipolar electrocautery 1 week after the first operation. Mediastinal paragangl...

Alveolar soft part sarcoma (ASPS) is a rare malignancy that usually arises in an extremity. Mediastinal involvement is uncommon, with only two reports of primary mediastinal disease and two reports of metastatic mediastinal disease in the literature, all referencing adult patients. To our knowledge, ours is the first report of ASPS presenting with a mediastinal mass in adolescence. Although ASP...

Primary mediastinal choriocarcinoma is a rare entity and is peculiar only to man. Although rigid criteria such as serial biopsies of the gonads are essential to rule out the possibility of such mediastinal tumor as a metastatic lesion, a review of the literature shows that anterior medlastinum is rarely involved by the metastasis from gonadal tumors. The clinical diagnosis of such a tumor can b...
