The article’s personal interpretation of pectoral myelomeningocele refers to what may be called pleurisy. Typical symptoms of pleurisy include chest pain, dyspnea, and chest tightness. When the pleura is attacked by a variety of inflammatory factors, it can cause both pleural adhesions, hypertrophy, and hyperplasia, as well as increased pleural exudation. When the pleura is adherent and hypertrophied, the dirty layer and the wall layer of the pleura will rub against each other when breathing, and the main symptom is pain when breathing, and the pleurisy at this time is dry pleurisy. When the exudation of the pleura increases, the patient’s pain during breathing exercise may gradually decrease or disappear, but with the increase of fluid in the chest cavity may produce pressure on the heart and lungs, resulting in symptoms such as dyspnea and chest tightness. In short, the typical symptoms of pleurisy are pain when breathing, chest tightness, chest pain, and dyspnea.
