Sequelae 1
• Radiological images: - retraction and fibrosis
- calcification
- bronchiectasis.
• One can observe sequelae in case of
“spontaneous recovery“ of a non treated TB.
Active BK remain alive in calcified cicatrix
An active TB can occur in the evolution
especially in case of immuno-depression.

Sequelae 2
• One can also observe sequelae after
an adapted treatment, especially if this
treatment is initialised with delay, if the
pulmonary lesions are severe, and if
the patient has diminished immune
defenses (HIV, malnutrition…) .
• It is always necessary to try to find
AFB in sputum before making the
diagnosis of inactive TB sequela.

Sequelae (3)
Sequelae can be symptomatic even without
active tuberculosis:
• Hemoptisis,
• Infections with non TB bacteria or aspergillus
• Dyspnea and chronic respiratory failure
• Do not treat again improperly with anti-TB in case of
AFB negative sampling in sputum

Sequelae (4)
• It is very important to store the old chest
x ray for comparaison with the recent
chest Xray
• The notion of a correct TB treatment in
the ATCD of the patient is a strong
argument for the diagnosis of sequelae (but exogenous reinfection is also possible)

Problem for the clinician
• Recognise real TB sequela, which can
give complications (hemoptisy, respiratory
insuffisiency, bacterial non tb infection...) but
which do not need a new TB treatment
• Recognise active TB, sometimes mixed
with older sequela lesions, which need TB
treatment
