Thanks for your question on HCM.
There are many causes for white patch on chest x ray. Common causes are
1. Infiltration mostly bacterial pneumonia
2. Tuberculosis
3. Old scar (healed Fibrotic) lesion. Etc
Since her Skin test and sputum both are negative for TB, white patch is less likely to be of tuberculosis.
CT THORAX gives excellent imaging of lung parenchyma. And thus will be more helpful in rule out above causes.
So get done CT and diagnosed her first.
