Abstract:
The patient was a 68-year-old woman with a history of multiple cerebral emboli. The patient presented with dysarthria, dysphagia, and left facial paralysis. Emergent MRI demonstrated multiple emboli in the brain stem and left occipital lobe. Echocardiography and chest CT demonstrated floating emboli entrapped in the foramen ovale and pulmonary emboli in both main pulmonary arteries. Emergent pulmonary embolectomy and extraction of the emboli on the foramen ovale were successfully performed without neurological exacerbation.

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.

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...
