History And Clinical Findings:
During a screening examination a pulmonary mass in the left lower lobe was detected in a 39-year-old man. The patient was asymptomatic and had hitherto been healthy. CT pulmonary angiography revealed an intralobar pulmonary sequestration with an afferent arterial branch from the thoracic aorta.
Diagnosis, Treatment And Course:
Thoracotomy with resection of the sequestration was performed. On the first postoperative day hemiparesis of the left side occurred because of an infarction of the arteria cerebri media. After aspiration of the thrombus and intraarterial thrombolysis the patient recovered completely. Histology of the sequestration showed invasive growth of aspergillus and severe inflammation, caused by invasive mycosis. Subsequently the patient received voriconazol for four weeks.
Conclusion:
Diagnosis of pulmonary sequestration in adults is rare. In asymptomatic patients there is still controversy about the treatment. Surgery, arterial embolisation and a "watch and wait" strategy can be taken into account. Because of the risk of infection an operative approach should be favoured.

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.
