Ascaris or eggs may be found in the sputum

Introduction Clinical symptoms of pulmonary ascariasis, or sputum or eggs can be found during sputum examination.

Cause

After accidentally swallowing the infected mites, the humans hatch in the small intestine and smash the shells and reach the lungs through three pathways:

1 through the small intestine mucosa, microvessels, portal vein, hepatic vein, inferior vena cava, right heart, pulmonary artery to lung;

2 through the small intestinal mucosa lymphatic duct, left heart to lung;

3 through the small intestine wall into the abdominal cavity and then into the lungs through the liver, diaphragm, chest. In the lungs, it can damage the pulmonary capillaries and alveoli to cause punctiform hemorrhage, alveolar bronchiolitis and eosinophilic infiltration, mucus secretion increase or eosinophilic granuloma formation. A large number of infections may have hemorrhagic pneumonia and lungs. Leaflet embolization. Adult worms can also enter the chest through the liver to the lungs, or through the venous system through the right heart to the lungs, but also through the pharynx, trachea, bronchus to the lungs, causing lung abscess, pulmonary embolism or asphyxia females can invade the lungs Local spawning, causing eosinophilic abscess, granuloma and pseudotuberculous nodules.

According to the comprehensive analysis of epidemiology, clinical manifestations and laboratory tests, the aphid infection is still dominated by parasitology.

Differential diagnosis

Pulmonary damage of pulmonary ascariasis should be differentiated from bronchopneumonia tuberculosis and leptospirosis.
