Consolidation in a child from tuberculosis endemic area - thinking apart from tuberculosis

Tuberculosis is endemic in South East Asian regions and hence a disease commonly over diagnosed in these parts of the country. Patients presenting with chest x ray shadows and vague symptoms are often started on Anti Tuberculosis Treatment - smear negative. However caution should be administered in prescribing ATT to patients who do not improve symptomatically, even after intensive phase. Congenital abnormalities such as sequestrated lung at times can also be rare causes of abnormal skiagram chest, especially in paediatric patients. A careful systematic approach with non invasive imaging such as CECT chest will often help to clinch the diagnosis in most cases.
