|January 15, 2026
Summary
Foreign body aspiration is rare in adults and can occur without a known incident. A case study highlights an occult endobronchial foreign body causing airway obstruction, leading to persistent pneumonia and lobar collapse in an adult patient.
Area of Science:
- Pulmonology
- Medical Case Reports
- Diagnostic Bronchoscopy
Background:
- Foreign body aspiration is infrequently diagnosed in adults.
- Symptoms can be nonspecific, lacking a clear history of aspiration.
- Persistent airway obstruction can lead to severe pulmonary complications.
Purpose of the Study:
- To report a case of occult endobronchial foreign body aspiration in an adult.
- To highlight the diagnostic challenges and clinical presentation.
- To emphasize the utility of bronchoscopy in identifying endobronchial foreign bodies.
Main Methods:
- Case report of an adult patient with persistent lobar collapse and pneumonia.
- Diagnostic bronchoscopy was performed to investigate airway obstruction.
- Identification and removal of an endobronchial foreign body.
Main Results:
- Bronchoscopy revealed an occult endobronchial foreign body.
- The foreign body was causing significant airway obstruction.
- Resolution of symptoms following foreign body removal (implied).
Conclusions:
- Occult foreign body aspiration should be considered in adults with unexplained lobar collapse and pneumonia.
- Bronchoscopy is a crucial diagnostic and therapeutic tool for endobronchial foreign bodies.
- Early identification and intervention can prevent severe pulmonary sequelae.

Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

01:30Pneumonia I: Introduction
728
Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

01:17Pulmonary Cycle: Exhalation
3.0K
In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
