Abstract:
Mycobacterium tuberculosis is a very rare cause of extracranial carotid artery pseudoaneurysm. A 39-year-old man presented with a rapidly increasing neck mass and hoarseness of voice for 15 days. He was on antitubercular treatment for pulmonary tuberculosis. Computed tomography angiography showed a large pseudoaneurysm of the right common carotid artery. Emergency surgery was performed to excise the pseudoaneurysm sac and repair the artery with a Dacron graft. Postoperative angiography showed normal flow in the carotids and cerebral circulation. Histology of the excised tissue was consistent with a tubercular etiology of the pseudoaneurysm.

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.
