Case Discussion
The patient is egyptian. Tuberculosis is endemic in Egypt, middle east area and India. Primary infection with TB occurs during childhood and result in ghon's focus and the calcified lymph node. Post-primary infection occurs later in life either by re-infection or re-activation. If the immunity is strong TB bronchopneumonia and abscess occur but if the immunity is weak miliary TB occurs. TB abscess favors the apical segment of upper and lower lobes due to their low oxygen tension.
