The PET Scan came back positive. This could mean that either she does have the PTLD or that she has a fungus that is causing inflamation.
She getting her bronch right now. Please, if you read this in the next several minutes, pray that the doctor is able to get a few good samples of her lungs from the areas showing the growths. If not, she'll need to be scheduled for a biopsy surgery, which will mean another trip to the OR, general anesthesia and a chest tube, all of which Tricia really wants to avoid.
I'll let you know more later.
