Findings: Chest radiographs show air-space disease in the right lower lobe (A-B, arrows). There is marked widening of the right paratracheal line (A, red arrow) suggestive of mediastinal lymphadenopathy.

Axial CT with lung window shows RLL air-space disease without cavitation (C, arrow). Mediastinal window at different levels confirms enlarged paratracheal, subcarinal and neck lymph nodes with hypodense center (D-F, red arrows). These findings should suggest active tuberculosis as the first possibility.
Although TB usually affects upper lobes, isolated involvement of lower lobes occurs in about 7% of cases.
 
Mycobacterium tuberculosis was found in the sputum.

Final diagnosis: active TB.
 
Congratulations to Archanareddyt who was the first to make the diagnosis.
 
 Teaching point: lymph nodes with hypodense center may occur in several processes (treated tumors, Whipple’s, etc.), but in the appropriate clinical situation, the first diagnostic consideration should be tuberculosis.
