Case Discussion

The lungs are the most common site of primary infection by tuberculosis and are a major source of spread of the disease and of individual morbidity and mortality. 

This case assumed to be a post primary tuberculosis.

The features of primary and post primary tuberculosis may overlap; however, the distinguishing features of post primary tuberculosis include a predilection for the upper lobes, the absence of lymphadenopathy, and cavitation1

Cavitation, the hallmark of post primary tuberculosis, affects about 50% of patients. The cavities typically have thick, irregular walls, which become smooth and thin with successful treatment. Cavities are usually multiple and occur within areas of consolidation1.
