parietal pleura

The serous membrane that lines the chest cavity; it extends from the mediastinal roots of the lungs and covers the sides of the pericardium to the chest wall and backward to the spine. The visceral and parietal pleural layers are separated only by a lubricating secretion. These layers may become adherent or separated by air or by blood, pus, or other fluids, when the lungs or chest wall are injured or inflamed.
Synonym: costal pleura

Extrapleural pneumonectomy is indicated in some cases of malignant mesothelioma and tuberculous empyema and involves resection of lung and parietal pleura with prosthetic reconstruction.
Gas can enter the pleural space through an opening in the visceral pleura from inside the lungs, or through a communication between the pleural space and the atmosphere through the chest wall and parietal pleura.
There was one patient in our study with primary pleural hydatid, In this patient, many cystic structures were drained, and complete decortication of the parietal pleura was performed.
These cysts were ribbon like and arranged along the mediastinal and parietal pleura, and could be the source of spontaneous pneumothorax in our case.
The apex of the lung is usually retained within the thorax by the muscles of the thoracic inlet, Sibson fascia, and the parietal pleura. Sibson fascia is also known as the deep cervical fascia, or suprapleural fascia, and acts like a diaphragm across the thoracic inlet, allowing the lung apex to rise above the first costosternal junction.
Neither cytological examination nor needle biopsy of the parietal pleura was able to establish the diagnosis.
Biopsies were performed under direct vision in all suspicious areas (Figure 1) and systematically in several parts of the parietal pleura for cytological and pathological examinations (Figure 2).
