Case contributed by Dr Heba Abdelmonem


Long term history of chest symptoms

Patient Data

Age: 50
Gender: Male

CT of the chest shows two calcified lymph nodes are seen at the subcarinal as well as prevascular regions.

Bilateral single calcified granulomas as well as the diffuse involvement of the upper lung lobes as well as apical segments of the lower lung lobes with fibrotic bands and secondarily bronchiectatic changes.

A small thin smooth walled cavity is in the apical segment of the left lower lung lobe.

CT findings may suggest possible post-primary tuberculous infection. 

Case Discussion

Postprimary tuberculosis is a term used to describe both reinfection and/or reactivation of tuberculosis. Primary tuberculosis is a self-limiting condition, on the other hand, post-primary tuberculosis is progressive.

Our case is a 50-year-old male patient with long history of chest symptoms. CT of the chest demonstrated multiple findings that may favor the possibility of post-primary tuberculous infection includes the calcified lymph nodes, calcified granulomas and bilateral apical band of fibrosis with secondarily bronchiectatic changes.
