Anytime we find nodules in your chest on CT, there is a differential (many different diagnoses) to consider. It seems that your doctors are doing a thorough job testing you for infections including Tuberculosis
and fungus. Other diseases that they are likely considering include sarcoidosis
, rheumatoid lung, Wegener's granulomatosis, and inhalational diseases. Unfortunately, the diagnosis also includes lymphoma
and lung metastases from primary cancer.
It sounds like you are in good hands, make sure you get close follow up. The next step may be more lab work, a follow up CT, or a tissue diagnosis.
Wish you good health,,,
