A patient presents with a chronic cough, night sweats, and weight loss. A chest X-ray reveals upper lobe cavitary lesions. Which of the following is the most likely diagnosis?

  • A. Tuberculosis
  • B. Pneumonia
  • C. Lung cancer
  • D. Sarcoidosis
Correct Answer: A

Rationale: The correct answer is A: Tuberculosis. Cavitary lesions in the upper lobes are classic findings seen in tuberculosis. This infectious disease commonly presents with symptoms such as chronic cough, night sweats, and weight loss. Pneumonia (Choice B) typically does not present with cavitary lesions on chest X-ray. Lung cancer (Choice C) may present with similar symptoms but is less likely to cause cavitary lesions in the upper lobes. Sarcoidosis (Choice D) usually presents with bilateral hilar lymphadenopathy and non-caseating granulomas, different from the cavitary lesions described in the case.
