TB or not TB; don't miss the obvious.

Tuberculosis (TB) is one of the leading causes of morbidity and mortality in the world. Its classic forms include cavitary and miliary TB. The non-specific clinical presentation of TB and similarity of its signs and symptoms with other pulmonary diseases makes its diagnosis difficult, especially in low burden settings like Arkansas. We emphasize the importance of early diagnosis and describe two cases where a delay resulted in complications and a prolonged treatment plan for the patients.
