Tissue of desmoid-type fibromatosis was used as a positive control for vimentin and [sz]-catenin, while tissues of leiomyoma, extrapleural
solitary fibrous tumor, and giant cell tumor, respectively, were used as a positive control for SMA, CD34, and CD68.
Solitary fibrous tumor can occur in extrapleural
The extent of pulmonary resection is of importance as a risk factor, with the highest rates of incidence noted after pneumonectomies, extrapleural
pneumonectomies and lung transplantations (2).
ligation of patent ductus arteriosus: a convenient surgical approach in a developing country.
By an extraperitoneal and extrapleural
approach retroperitoneum entered; a huge mass pushing the bowels anterior and medially with lot of parasitic vessels invading Gerotas covering the mass.
5) Pitfalls in the determination of pleural effusions, regardless of patient positioning, include overlying soft tissue, atelectasis, extrapleural
fat, pericardial fat, and pleural thickening.
Other signs that suggest mediastinal air on the CXR include the 'continuous diaphragm sign' (air trapped posterior to the pericardium), 'Naclerio's V sign', which is formed by the junction of mediastinal air in the left lower mediastinum and extrapleural
air adjacent to the left hemidiaphragm, the 'V sign' that is formed by the confluence of the superior margins of the brachiocephalic veins, the 'ring around artery sign' that results from air outlining the pulmonary artery and the main branches, the 'double bronchial wall sign' formed by air outlining the bronchi, air in the pulmonary ligament and irregular bilateral apical extrapleural
pneumonectomy is usually performed for stage I disease, when the tumor is limited to one hemithorax, invading the pleura and involving the lung, endothoracic fascia, diaphragm, or pericardium.
This imaging method allows evaluation of the extent of the perforation based on associated findings such as mediastinitis, pleural effusion, extrapleural
collections, and intraperitoneal effusion .
Radiography in all cases revealed a large expansile rib lesion and an associated extrapleural
soft- tissue mass.
1) The presence of these tumors has also been reported in a number of extrapleural
sites such as the lung, mediastinum, and meninges.
3] However, it is not anatomically restricted to the chest cavity and has been described in various extrapleural
sites, such as upper respiratory system, lung, liver, nasal cavity, paranasal sinuses, mammary glands, orbita, mediastinum, greater salivary glands, meninges, and even the kidney.
