CONTEXT With the advent of modern anatomical and functional imaging technologies, application of cervical mediastinoscopy has decreased in diagnosis and staging of mediastinal diseases. AIM To evaluate the usefulness of cervical mediastinoscopy in assessing the mediastinal disease when imaging modalities are non-diagnostic. SETTINGS AND DESIGN Retrospective analysis of records of a tertiary...

Myelolipoma (ML) is an uncommon benign mesenchymal neoplasia composed of mature adipose and hematopoietic tissues of uncertain etiology. Less than 3% of MLs occur in the mediastinal topography. The main differential diagnosis involves extramedullary hematopoiesis; therefore, pathological evaluation is essential for the definitive diagnosis. The authors report the case of a 50-year-old man diagn...

A Mexican woman, aged 71 years, with life-long exposure to soot from a wood cook stove in a closed environment, who was treated for tuberculosis 4-years prior, presented with prominent mediastinal lymphadenopathy with anthracosis. Mediastinal lymphadenopathy is a common presentation of diverse granulomatous, malignant and infectious conditions like tuberculosis. Anthracotic pigment is found in ...

Congenital cysts are typically unilocular and thin-walled to the point of translucency; careful histopathologic examination shows no evidence of inflammation. In contrast, acquired thymic cysts are usually multilocular, hence the commonly used term “multilocular thymic cyst (MTC).” These cysts have thick, fibrous walls, and histopathologic examination typically reveals significant inflammation ...

A parathyroid lipoadenoma is a very rare cause of mediastinal mass. The clinical features of this pathologic entity is similar to those of the more common pathologic variants of parathyroid disease associated with primary hyperparathyroidism. A 58-year-old woman presented with huge multinodular goiter. Her thoracic CT scan was done before surgery, showed a posterior mediastinal mass. On microsc...

BACKGROUND AND OBJECTIVES Video-assisted thoracoscopy has been successfully used for several different thoracic procedures in adults. However, its use in children has been limited. The present study evaluated our experience with video-assisted thoracoscopy in the diagnosis of mediastinal masses in children. METHODS Nine children (age range, 3 to 18 years) with undiagnosed mediastinal masses u...

INTRODUCTION The thorax is an area in which distant metastases are frequently observed because it is located on the hematologic and lymphatic pathways (1). Various malignant neoplasms can metastasize to the lung (parenchymal or endobronchial), the hilar-mediastinal lymph nodes, pleura, pericardium, or to the chest wall. The lungs and mediastinum, especially, are the places where other malignanc...

BACKGROUND Acquired myasthenia gravis (MG) in cats most commonly causes generalized weakness without megaesophagus and is more often associated with a cranial mediastinal mass, compared to dogs. HYPOTHESIS/OBJECTIVES To extend the clinical findings described in the report of 2000 on MG in cats (J Am Vet Med Assoc 215:55-57). ANIMALS Two hundred and thirty-five cats with MG. METHODS Retros...
