Introduction:
Benign metastasizing leiomyoma (BML) is a rare cause of pulmonary nodules. They can occur in women of reproductive age who have undergone hysterectomy for uterine leiomyoma.
Observation:
We report the case of a 46-year-old women, who was incidentally found to have bilateral pulmonary cavitating nodules. Pathology exam was consistent with BML.
Conclusion:
Although BML is a rare cause of pulmonary nodules, it should be considered as one of the possibilities especially in young women with a history of hysterectomy for leiomyoma.

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.

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...

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...

Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...
