Pleural calcification generally poses no major danger. It is typically a result of incomplete treatment of pleuritis or prolonged illness that delays the disease management, causing the disease to progress and the pleura to develop adhesions, leading to the deposition of calcium salts on the pleura and resulting in calcification. Depending on the extent of this pleural calcification, if severe, it may affect lung expansion and thereby reduce respiratory function. However, most cases do not exhibit significant symptoms. Moreover, it does not greatly impact the patient's life or quality of life. Therefore, when such calcification is observed, it is generally recommended that the patient be advised to attend regular follow-up checks. It does not necessarily cause any special symptoms, so there is no need for concern.
