A pleural effusion is accumulation of excessive fluid in the pleural space, the potential space that surrounds each lung.Under normal conditions, pleural fluid is secreted by the parietal pleural capillaries at a rate of 0.6 millilitre per kilogram weight per hour, and is cleared by lymphatic absorption leaving behind only 5–15 millilitres of fluid, which helps to maintain a functional ...
Corns from an acute injury, such as from a thorn in the sole of the foot, may form due to the weight of the body, when the process that creates the usually evenly developing plantar callus is concentrated at the point of the healing injury, as an internal callus may be triggered by pressure on the transitional scar tissue. Once formed, the corn ...
Pleurisy Pleural linings and space (marked in blue) The pleural space can be invaded by fluid, air, and particles from other parts of the body, which fairly complicates diagnosis. [12] [13] Viral infection (coxsackie B virus, HRSV, CMV, adenovirus, EBV, parainfluenza, influenza, COVID-19) is the most common cause of pleurisy.
The costodiaphragmatic recess, also called the costophrenic recess or phrenicocostal sinus, [1] is the posterolateral fringe of the pleural space, a potential space around the lung inside the pleural cavity. It is located at the acutely angled junction ("reflection") between the costal and diaphragmatic parietal pleurae, and is interpreted two ...
The location of the lesions is mostly in the upper lobes of the lungs, usually in a lymphatic distribution. Thickening of the pleura and interlobular septal is also evident. In addition, pleural/pericardial effusions and mediastinal fat infiltration is appreciated. Definitive diagnosis is achieved through tissue biopsy. [1]
The pleurae (sg.: pleura) [1] are the two flattened closed sacs filled with pleural fluid, each ensheathing each lung and lining their surrounding tissues, locally appearing as two opposing layers of serous membrane separating the lungs from the mediastinum, the inside surfaces of the surrounding chest walls and the diaphragm.
Pleural disease occurs in the pleural space, which is the thin fluid-filled area in between the two pulmonary pleurae in the human body. There are several disorders and complications that can occur within the pleural area, and the surrounding tissues in the lung .
The pleural fluid is most often straw-colored, and it has a distinct smell like ammonia. The fluid usually has a nucleated cell count between 50 and 1500 per cm 3. [4] The pH of the fluid is usually between 5 and 7. [9] Primary factors for diagnosing urinothorax by pleural fluid include low protein and high lactate dehydrogenase content. [10]
