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 ...
Fibrothorax may also occur without a clear underlying cause, in which case it is known as idiopathic fibrothorax. A technique called pleurodesis can be used to intentionally create scar tissue within the pleural space, usually as a treatment for repeated episodes of a punctured lung, known as a pneumothorax, or for pleural effusions caused by ...
Abdominal ultrasonography and CT scan can help diagnose the underlying condition of the genitourinary tract. If other methods prove inconclusive, an accurate diagnosis can be made by a technetium-99m kidney scan, which shows albumin labeled with 99Tc that translocates into the pleural space from the genitourinary tract.

A diagnosis of pleurisy or another pleural condition is based on a medical history, physical examinations, and diagnostic tests. [12] The goals are to rule out other sources of the symptoms and to find the cause of the pleurisy so that the underlying disorder can be treated.
Because the transdiaphragmatic lymphatic channels are larger in diameter on the right, the pleural effusion is classically on the right side. The causes of the ascites and pleural effusion are poorly understood. [1] Atypical Meigs syndrome, characterized by a benign pelvic mass with right-sided pleural effusion but without ascites, can also occur.
Hydrothorax is the synonym of pleural effusion in which fluid accumulates in the pleural cavity. This condition is most likely to develop secondary to congestive heart failure, following an increase in hydrostatic pressure within the lungs. More rarely, hydrothorax can develop in 10% of patients with ascites which is called hepatic hydrothorax ...
Primary effusion lymphoma (PEL) is a HHV8+ B cell lymphoma presenting as an effusion (i.e. excess fluid) in the pleural cavity (see pleural effusion), peritoneal cavity (see peritoneal effusion), or pericardium (see pericardial effusion). These effusions are due to the infiltration of HHV8-infected B cells into the membrane tissues that line ...
A chylothorax is an abnormal accumulation of chyle, a type of lipid-rich lymph, in the pleural space surrounding the lung.The lymphatic vessels of the digestive system normally return lipids absorbed from the small bowel via the thoracic duct, which ascends behind the esophagus to drain into the left brachiocephalic vein.
