Mine was referred to as malignant neoplasm of intrathoracic lymph nodes. Had a bronchoscope airway exam with endobronchial ultrasound biopsy of nodes on both sides of airway. Had 5 sessions of SBRT . Had two psma within a couple of months prior to biopsy and one scan showed the left brighter than the right and the next scan showed the opposite. In the end only one was positive. The psma scan also showed contradiction in pelvic and vertebrae . Because of the these PSMA's being questionable biopsy's are necessary before treatment.
