We retrospectively analyzed the features of the size, morphology, attenuation, the enhancement patterns, and anatomic distribution of 45 patients with mediastinal tuberculous lymphadenitis shown on contrast-enhanced multislice spiral CT (MSCT). 80% of the patients showed peripheral enhancement, and 38% of them showed multilocular appearance. deltaCT (The CT on enhanced scan minus that on the unenhanced scan) in the central area (15 +/- 12) HU was less than that in the peripheral area (27 +/- 16) HU (P < 0.01). The enlarged lymph nodes were predominantly distributed in the regions of 4R (87%), 2R (76%), 7 (73%), 10R (62%), and 4L (51%). MSCT could reveal the enhancement patterns and predominant anatomic distribution, which was of great value for the diagnosis of mediastinal tuberculous lymphadenitis.

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 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...

Mitral Stenosis II: Clinical features and Diagnostic Tests

Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...
