Abstract:
A 59-year-old woman with a history of both breast and lung cancer developed a new 1.5 cm solitary pulmonary nodule on computed tomography (CT) scan. The nodule had increased 18F-fluorodeoxyglucose (FDG) uptake on positron emission tomography (PET) with a standard uptake value (SUV) of 3.4. A CT guided biopsy was performed, and Mycobacterium avium complex (MAC) was identified. PET scans have become an important part of the diagnosis, staging, and follow-up of cancer. Even in individuals at considerable risk for cancer with a solitary nodule demonstrating increased FDG uptake, further diagnostic evaluation and needle biopsy might receive consideration prior to surgical intervention.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
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.
