This PA chest radiograph demonstrates an abnormal contour in the right hilar region, with visualization of the pulmonary vessels through the mass (the hilar overlay sign) indicating its posterior mediastinal location. On resection this was found to be a benign solitary fibrous tumor of the pleura.
Solitary fibrous tumor (SFT), also known as fibrous tumor of the pleura, is a rare mesenchymal tumor originating in the pleura [1] or at virtually any site in the soft tissue including the seminal vesicle. [2] Approximately 78% to 88% of SFT's are benign and 12% to 22% are malignant. [3]
Splaying of the carina can also suggest a tumor or process in the middle mediastinum or enlargement of the left atrium, with a normal angle of approximately 60 degrees. The right paratracheal stripe is also important to assess, as it can reflect a process in the posterior mediastinum , in particular the spine or paraspinal soft tissues ...
A mediastinal tumor is a tumor in the mediastinum, the cavity that separates the lungs from the rest of the chest. It contains the heart , esophagus , trachea , thymus , and aorta . The most common mediastinal masses are thymoma (20% of mediastinal tumors), usually found in the anterior mediastinum, followed by neurogenic Timor (15–20% ...
Mediastinoscopy is a procedure that enables visualization of the contents of the mediastinum, usually for the purpose of obtaining a biopsy. [1] Mediastinoscopy is often used for staging of lymph nodes of lung cancer or for diagnosing other conditions affecting structures in the mediastinum such as sarcoidosis or lymphoma.
The double bronchial wall sign is best visualized on CT, which provides high-resolution images of the mediastinal structures. The double bronchial wall sign is commonly seen in the central bronchi, particularly in the trachea or mainstem bronchi, where air is more likely to outline the structures.
A pneumonectomy is a surgical procedure in which an entire lung is removed. A common reason for performing this procedure is for lung cancer originating in the lung itself. [19] This leads to a mediastinal shift towards the empty side of the thorax. Notably, patients can experience post pneumonectomy syndrome due to a severe mediastinal shift.
Video-assisted thoracoscopic surgery (VATS) is a type of minimally invasive thoracic surgery performed using a small video camera mounted to a fiberoptic thoracoscope (either 5 mm or 10 mm caliber), with or without angulated visualization, which allows the surgeon to see inside the chest by viewing the video images relayed onto a television screen, and perform procedures using elongated ...
