Epituberculosis Revisited: Case Report and Review.

Area of Science:

• Pediatric Pulmonology
• Infectious Diseases
• Radiology

Background:

• Primary pulmonary tuberculosis frequently involves regional lymph nodes.
• Enlarged lymph nodes can cause bronchial compression or inflammation.
• Lymph node erosion into the bronchus leads to pneumonia, termed epituberculosis.

Observation:

• A 13-year-old presented with right hilar lymphadenopathy and right upper lobe consolidation on chest X-ray.
• Fibreoptic bronchoscopy revealed lymph node perforation and caseous material discharge into the upper lobe bronchus.
• This caused endobronchial obstruction, consistent with epituberculosis.

Findings:

• Epituberculosis resulted from a ruptured tuberculous lymph node extruding caseous material.
• The condition caused significant radiological findings including hilar lymphadenopathy, atelectasis, and consolidation.
• Endobronchial obstruction was identified as the direct cause of the observed pneumonia.

Implications:

• Ruptured tuberculous lymph nodes can mimic worsening disease or drug resistance.
• This presentation does not indicate the development of drug resistance in pediatric tuberculosis.
• Patients with epituberculosis respond well to standard anti-tuberculosis treatment regimens.
