Is extrapulmonary TB curable?

In contrast with PTB treatment, cure for EPTB is difficult to define. Moreover, there are no established criteria for the end of treatment. In case of studies on TB lymphadenitis, residual lymph nodes at the end of treatment have usually been used for assessing treatment outcomes.

How do TB become extrapulmonary?

Pulmonary and Extrapulmonary Tuberculosis If the infection is not contained by the immune system, in around 3–8 weeks, local spread and spread to regional lymph nodes in the lungs occurs. Subsequent spread to other organs results in extrapulmonary tuberculosis (EPTB).

Can HRCT detect TB?

High Resolution Computed Tomography (HRCT) has been discovered to be more sensitive than chest x-ray in the identification of small exudative lesions, slight or occult parenchymal disease and in assessing disease activity in pulmonary TB.

Can extrapulmonary TB spread to lungs?

While the majority of TB infections affects the lungs, TB can infect any place in the body: the inner organs, the bone, the brain, the spine etc. If TB infection is not primarily located in the lungs, it is called extrapulmonary TB (extra = outside of, pulmonary = affecting the lung).

How long is extrapulmonary TB treated?

Purpose: The recommended duration of pulmonary tuberculosis therapy is 6 months.

Can a CT scan confirm TB?

Imaging tests If you’ve had a positive skin test, your doctor is likely to order a chest X-ray or a CT scan. This might show white spots in your lungs where your immune system has walled off TB bacteria, or it might reveal changes in your lungs caused by active tuberculosis.

Which imaging findings are characteristic of tuberculous complications of lung cancer?

Imaging findings in tuberculous complications. (A) Axial CT lung window (window center -600 HU, width 1200 HU) shows thin-walled cavities in both upper lobes and presence of aspergilloma in RT upper lobe cavity.

Which radiographic findings are characteristic of pulmonary tuberculosis (TB) in 18-year-olds?

Pulmonary tuberculosis in 18-year-old boy with typical radiographic findings. Chest radiograph shows cavitary nodule (arrow) with multiple small nodules (arrowheads) in left upper lung zone. Open in a separate window Fig. 3 Pulmonary tuberculosis in 18-year-old boy with atypical radiographic findings.

What is the role of chest radiograph in the diagnosis of tuberculosis?

Chest radiograph (CXR) finds its place in sputum-negative patients not responding to a course of antibiotics. Though computed tomography (CT) is frequently employed in the diagnosis and follow-up of TB, it does not find a place in the national and international guidelines.

Which imaging studies are used in the diagnosis of tuberculosis (TB)?

Though computed tomography (CT) is frequently employed in the diagnosis and follow-up of TB, it does not find a place in the national and international guidelines. Literature is lacking and no consensus exists on use of ultrasound (USG), CT, and magnetic resonance imaging (MRI) in such patients.
