A chest X-ray of a 30-year-old male shows a Ghon's focus with ipsilateral hilar lymphadenopathy. This radiological complex is known as:

  • A Simon's focus
  • B Puhl's focus
  • C Ranke's complex
  • D Assman's focus
Correct answer: C. Ranke's complex

Explanation

The Ranke's complex (also called primary complex) consists of the Ghon's focus (primary parenchymal lesion, usually subpleural in upper part of lower lobe or lower part of upper lobe) plus the ipsilateral hilar lymphadenopathy. Simon's focus and Assmann's foci are related to post-primary TB. Puhl's focus is an apical pleural focus of TB. Ranke's complex represents healed primary tuberculosis.
