Extra-Pulmonary Tuberculosis

What is the differential diagnosis of tuberculosis?

Extra-Pulmonary Tuberculosis

Extra-Pulmonary Location Differential Diagnosis
Tuberculous Arthrits Bacterial septic arthritis, pseudogout
Central Nervous System Tuberculosis Bacterial meningitis, viral meningitis, encephalitis
Tuberculosis Peritonitis Bacterial peritonitis, chronic peritoneal dialysis

What are the different kinds of PTB findings?

Typical CT findings of reactivation of pulmonary TB include centrilobular small nodules, branching linear opacities, patchy consolidation, and cavitation (19–21). Post-primary TB most commonly involves the upper lobes and the superior segments of the lower lobes (25, 26).

What are differential diagnosis for pneumonia?

Overview. Pneumonia should be differentiated from other conditions that cause cough, fever, shortness of breath and tachypnea, such as asthma, COPD, CHF, cancer, GERD, pulmonary emboli.

What is the diagnosis of pulmonary tuberculosis?

To diagnose pulmonary TB specifically, a doctor will ask a person to perform a strong cough and produce sputum up to three separate times. The doctor will send the samples to a laboratory. At the lab, a technician will examine the sputum under a microscope to identify TB bacteria.

What is the difference between TB and pneumonia?

Based on presentation and findings on CXR, TB can mimic a variety of pneumonias: typical, atypical, aspiration. It can classically be distinguished from these based on a longer duration of symptoms and more systemic symptoms such as weight loss, and night sweats.

Does chest CT show TB?

Chest CT may be useful in identifying active tuberculosis even if the chest radiograph is negative, although chest CT is not the standard of practice (28). Consolidation and Cavitation. —Patchy, poorly marginated consolidation is an early and consistent feature of postprimary tuberculosis (Fig 11).

What is the difference between TB and PTB?

Pulmonary tuberculosis (PTB) is an infectious disease that involves the lungs and can be lethal in many cases. Tuberculosis (TB) in children represents 5 to 20% of the total TB cases.

What is the differential diagnosis of atypical pneumonia?

Over the past decades, atypical pneumonia has come to mean lower respiratory tract infections due to specific respiratory patho- gens, i.e., Chlamydia psittaci (psittacosis), Francisella tularensis (tularemia), Coxiella burnetii (Q fever), Chlamydia pneumoniae, Mycoplasma pneumoniae or Legionella species [1–5].

What is the most sensitive test for tuberculosis?

If sputum smears and NAA tests are negative, and TB is still suspected, cultures are the most sensitive tests for TB. Culture is therefore very useful for diagnosing both smear-negative TB and drug-resistant TB.

How do you document differential diagnosis?

Steps involved in a differential diagnosis

  1. What’re your symptoms?
  2. How long you have been experiencing these symptoms?
  3. Is there anything that triggers your symptoms?
  4. Is there anything that makes your symptoms worse or better?
  5. Do you have a family history of specific symptoms, conditions, or diseases?
