Abstract:
A 63-year-old male presented with loss of appetite, subfebrile fever, swelling of the right hand and dyspnea on exertion for three months. Past medical history revealed methotrexate treatment of six months for rheumatoid arthritis. Chest radiography and computed tomography (CT) revealed diffuse miliary nodules. PET/CT scan demonstrated diffuse FDG uptake in both lungs, in the spleen, in the right hand, the mediastinal and the axillary lymph nodes. MR of the right hand showed inflammatory arthritis. Histopathology of the right hand tru-cut biopsy revealed degenerative changes. Culture of the hand biopsy tissue was positive for mycobacterium tuberculosis. PET/CT may determine the biopsy and the sampling sites for the early diagnosis of patients with suspected miliary tuberculosis where lesion identification on other modalities may be difficult or unfeasible. High sensitivity for inflammatory diseases makes PET/CT a useful diagnostic utility for enabling early diagnosis in miliary tuberculosis which is a diagnostic predicament.

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...

Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...
