Tuberculosis is usually a slow incidious disease which manifests as a chronic productive or nonproductive cough. Very often hemoptysis is seen as the disease progresses. I would like to know if she became progressively hypoxic and dyspneic. Very often, in medicine, the last doctor to see the patient is the hero because he has the benefit of seeing the disease state well along in its manifestations. She should have lost weight, manifested a fever (of unknown origin), chronic cough, and a chest X-ray which showed apical cavitation of the lungs and lymphadenopathy. It would be difficult to write those physical findings as the findings of lovesickness in an adolescent.
It does seem, however, based upon a very superficial reading of this report that the family physician screwed the pooch and the child paid the price.
Did you see the part where her father is being treated for TB, a former classmate had TB, and the went to Pakistan recently on a trip? Add all that with her symptoms and it should have been a no brainer. A simple sputum test would have shown it immediately..........
