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...
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 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 I01:29

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.

Pleura of the Lungs01:13

Pleura of the Lungs

The lungs are nestled in a cavity, shielded by the pleura. The pleura, a form of serous membrane, wraps around each lung. This membrane arrangement consists of two layers: the visceral and parietal pleurae. The visceral pleura lines the surface of the lungIn contrast, the parietal pleura is the outer layer and contacts to the thoracic wall, the mediastinum, and the diaphragm. The hilum is the point of connection between the visceral and parietal layers. The space between the parietal and...

Pleural Effusion II: Symptoms and Management

Pleural Effusion Overview
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.

Area of Science:

  • Pulmonology
  • Infectious Diseases
  • Pathology

Background:

  • Bronchopulmonary tuberculosis (TB) can manifest as a pseudotumor, a rare entity that mimics malignancy clinically and radiologically.
  • This presentation occurs in immunocompetent patients and can lead to delayed diagnosis and treatment.
  • The incidence of bronchopulmonary pseudotumors is estimated to be 2-4% in various studies.

Purpose of the Study:

  • To report a rare case of a pleural-based tubercular pseudotumor.
  • To highlight the diagnostic challenges and clinical presentation of such cases.
  • To review the literature on mycobacterial pseudotumors of the pleura.

Main Methods:

  • Case report of a 59-year-old patient with a four-month history of cough and chest pain.
  • Radiological investigation revealing a right lower hemithorax pleural-based mass.
  • Histopathological analysis of the resected mass.

Main Results:

  • Initial biopsy suggested a hyalinizing variant of an inflammatory pseudotumor.
  • Surgical resection confirmed the mass as a tubercular granuloma.
  • The patient presented with nonspecific symptoms of cough and chest pain.

Conclusions:

  • Pleural-based tubercular pseudotumors are rare but should be considered in the differential diagnosis of lung masses.
  • The varied presentation necessitates a high index of suspicion for bronchopulmonary TB.
  • Prompt diagnosis and treatment are essential to prevent complications.
