I'd be really careful with the diagnosis. I was diagnosed with Aspergillosis first time, set me back a year and I found out later that taking Voriconazole (prescribed for Aspergillosis) was harmful for future skin problems. Dermatologist informed me of this. I've never heard of a light case, so maybe ask your doctor exactly what is meant by a light case. Perhaps it's not cavitary; that would be great! Perhaps another reason. There's so much info as we go through this journey that it's overwhelming to keep asking questions and keeping track of all the info. Doctors are stressed about this disease I believe because it is so under diagnosed and SO LITTLE has done to advance this disease since the BIG 3 was first administered for this. Keep asking questions. Best to you on this journey.
