Abstract:
Bronchial artery-pulmonary artery fistulae are rare vascular malformations most commonly caused by infection. Our case presents a 57-year-old male who presented to the Emergency Department with a symptomatic bronchial artery-pulmonary artery fistula due to cavitating pulmonary tuberculosis (TB). The diagnosis was made with multiphase CT angiography of the thorax (including pulmonary and systemic arterial phases). The patient was brought to interventional radiology for further investigation and management. The left upper lobe bronchial artery-pulmonary artery fistula was successfully identified and treated with endovascular embolization. Bronchial artery-pulmonary artery fistulae can pose a diagnostic and therapeutic challenge. Our case demonstrates endovascular embolization as an effective method of treating symptomatic bronchial artery-pulmonary artery fistulae.

Pulmonary Tuberculosis II
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Pneumothorax-I
Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.
Overview of Pulmonary Circulation
The process begins with the right ventricle of the heart pumping deoxygenated blood into the pulmonary trunk. This large vessel extends about 5 centimeters before splitting into the left and right pulmonary arteries. These arteries...
