Pulmonary Tuberculosis III01:31

Pulmonary Tuberculosis III

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:
Pulmonary Tuberculosis II01:28

Pulmonary Tuberculosis II

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
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...

Tuberculosis

Tuberculosis (TB) remains a significant global health concern, primarily targeting the lungs and spreading through airborne transmission. Infection begins when aerosolized droplet nuclei, expelled by an individual with active TB, are inhaled by another person. These microscopic particles carry Mycobacterium tuberculosis, the causative agent of TB. Upon reaching the alveoli, the bacilli are engulfed by alveolar macrophages. However, due to their specialized lipid-rich cell wall, these pathogens...

Pulmonary Tuberculosis I

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
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.
Mode of...
Pulmonary Tuberculosis IV01:26

Pulmonary Tuberculosis IV

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
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 V

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
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 progression...

Summary

Delayed diagnosis of miliary tuberculosis occurred in a patient presenting with sacroiliac joint pain. Early awareness of tuberculous sacroiliac joint infection is crucial for timely detection and treatment.

Area of Science:

  • Infectious Diseases
  • Radiology
  • Orthopedics

Background:

  • Miliary tuberculosis results from widespread hematogenous dissemination of Mycobacterium tuberculosis.
  • Tuberculous sacroiliac joint infections are uncommon, often presenting with diagnostic challenges and delayed recognition.

Observation:

  • A 28-year-old male presented with a five-month history of left sacroiliac joint pain.
  • Initial investigations failed to yield a diagnosis, prompting planning for an open biopsy.
  • Chest X-ray revealed diffuse, bilateral opacities, leading to a diagnosis of miliary tuberculosis.

Findings:

  • Miliary tuberculosis involves multiple organ systems and can be treated empirically due to difficulties in microbiologic verification.
  • Diagnosis of bone and joint tuberculosis is frequently delayed due to its rarity, varied presentations, and subtle radiographic findings.

Implications:

  • This case underscores the importance of maintaining a high index of suspicion for miliary tuberculosis in patients with persistent, unexplained joint pain.
  • Early detection and treatment of tuberculous sacroiliac joint infections are critical to prevent disease progression and improve patient outcomes.
