Pulmonary Tuberculosis II01:28

Pulmonary Tuberculosis II

211
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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

86
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
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...

Pulmonary Tuberculosis III

303
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 I01:29

Pulmonary Tuberculosis I

220
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.

Area of Science:

  • Pulmonology
  • Pathology
  • Oncology

Background:

  • Pulmonary nodular lymphoid hyperplasia (PNLH) is a rare lymphoproliferative disorder of the lung.
  • PNLH often lacks distinct clinical and imaging features, complicating preoperative diagnosis.
  • Diagnosis typically requires postoperative pathological examination.

Observation:

  • A 57-year-old female presented with a pulmonary nodule found during a routine exam.
  • Chest CT revealed a mixed ground-glass nodule with suspicious features like lobulation and spiculation.
  • Initial imaging suggested a possible pulmonary malignancy.

Findings:

  • Postoperative pathological examination confirmed the diagnosis of PNLH.
  • Immunoglobulin heavy chain (IgH) gene rearrangement analysis supported the PNLH diagnosis.
  • The case presented atypical imaging findings for PNLH.

Implications:

  • This case underscores the difficulty in diagnosing PNLH preoperatively.
  • It highlights the critical role of histopathology in differentiating PNLH from malignant lung tumors.
  • Accurate diagnosis is essential for appropriate patient management and avoiding unnecessary aggressive treatments.
