Pulmonary Tuberculosis IV

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 III

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:

Area of Science:

Radiology
Hepatology
Infectious Diseases

Background:

Tuberculosis (TB) presents with varied imaging characteristics in the liver.
Findings can range from hepatomegaly to focal lesions, potentially mimicking hepatic tumors.
Biliary tract involvement, including ductal dilatations and strictures, can also occur.

Purpose of the Study:

To review the spectrum of imaging findings in hepatic tuberculosis.
To highlight the challenges in diagnosing TB based on imaging alone.
To emphasize the role of various imaging modalities in evaluating suspected liver TB.

Main Methods:

Review of cross-sectional imaging studies (ultrasound, CT, MRI) in patients with confirmed hepatic tuberculosis.
Analysis of imaging features, including lesion morphology, distribution, and associated findings.
Correlation of imaging findings with clinical and histopathological data.

Main Results:

Hepatic TB demonstrates a wide array of imaging appearances, including nonspecific hepatomegaly, abscesses, and solid focal lesions.
Lesions can mimic primary or secondary liver malignancies.
Imaging may reveal biliary tract abnormalities such as ductal dilatation secondary to tuberculous strictures.

Conclusions:

Cross-sectional imaging modalities like ultrasound, CT, and MRI are valuable in assessing hepatic tuberculosis.
The diverse and often nonspecific imaging findings can be challenging for radiologists, especially in non-endemic regions.
Histopathological confirmation is frequently necessary for definitive diagnosis of hepatic TB.
