Which of the following conditions does he most likely to have?
During a cardiac arrest, a 58-year-old man, a non-smoker, receives cardiopulmonary resuscitative measures and is brought to the hospital, where he is intubated. During the intubation procedure, he suffers aspiration of gastric contents (pasta with mushrooms and peas). Over the next 10 days he develops a non-productive cough along with a fever to 37.9 C. A chest radiograph reveals a 4 cm diameter mass with an air-fluid level in the right lung. A sputum gram stain reveals mixed flora.
A. Squamous cell carcinoma B. Lung abscess C. Chronic bronchitis D. Bronchiectasis E. Bronchopulmonary sequestration
Lung abscess -(b) correct. a lung abscesses can result from aspiration of oropharyngeal or nasopharyageal contents, where bacterial organisms as part of normal flora can be picked up and transported to the lungs. the straighter bronchus to the right lung is more likely to conduct aspirated material. with septicemia, multiple abscesses are more likely to be present.(d) incorrect. bronchiectasis can occur from chronic bronchial inflammation and destruction following obstruction and/or infection; cystic fibrosis is the best known disease to produce a widespread pattern of bronchiectasis. with obstruction, it depends upon the cause for the obstruction where the focus of bronchiectasis will be.(e) incorrect. sequestrations are masses of lung tissue without a normal connection to the airways. they act as space occupying lesions and can cause obstruction.
