My wife has severe aplastic anemia and after a 5-day treatment developed fungal pneumonia. She had pleural effusion that required drainage for several days. Several liters of fluid were removed. She was treated with antifungal meds and follow with CT scans. She’s had several nodules in her lungs that have shrunken. It’s not a problem now but is still followed. Effusion has stopped for several months. Talk to your doctor about treatment plans. In my wife’s case the treatment has been successful. I hope yours can be too.
