Nodal pleural pull is usually a manifestation of a lesion pulling on the pleura of the dirty layer, creating a triangular internal pleural depression.
Nodal pleural pulling may be caused by more fibrous tissue proliferation in the internal structures of the lesion, and pleural depression and thickening of pleural adhesions in the dirty layer due to pulmonary atelectasis. Intrapulmonary disease, such as pulmonary nodules leading to pleural depression sign causes pleural pulling.
There are no clinical symptoms in the early stages of nodular pleural pulling. In the later stage, the symptoms are different depending on the disease. If the nodular pleural involvement is accompanied by coughing and hemoptysis, hot flashes (fever in bursts), night sweats (sweating abnormally after going to sleep and stopping after waking up), and gradual loss of weight, consider tuberculosis; if the nodular pleural involvement is accompanied by cough, chest pain, fever, and coughing up sputum with a fishy odor, consider lung abscess.
As malignant tumor cells grow and multiply faster, they can invade the lungs and surrounding tissues, easily causing necrosis of lung tissues and formation of nodular foci. If the malignant tumor cells metastasize to the pleura and infiltrate the pleura, it can cause pleural pulling, which is malignant at this time and seriously affects the patient’s life expectancy.
If the patient has nodular pleural pulling, it is recommended to seek timely medical treatment under the guidance of the doctor.
