Pleurisy is relatively common in clinical settings, with numerous and complex triggering factors. It is often caused by an infection of Mycobacterium tuberculosis invading the pleural cavity, leading to inflammatory lesions. This often results in exudative inflammation, where fluid leakage into the pleural cavity can occur, but pleurisy generally does not cause ascites. The formation of ascites may have an indirect relation to pleurisy, but it primarily depends on the presence of other factors, such as acute pelvic inflammatory disease, chronic kidney diseases, or liver diseases, which could all potentially lead to the formation of ascites in patients.
