False positive for tumour PET/CT-findings (TBC)
Images of PET/CT-findings of lesions, that had been false-positive for malignant tumours; pulmonary Tuberculosis (TBC) was diagnosed post Wedge Resection (excisional biopsy during Exploratory mini thoracotomy).

IMAGES 1-6: Solid mass (max. dim. 1.7 cm, SUVmax: 12) of the right lung (RLL) in a 50-yo male smoker’s case (50 pack-yrs).

IMAGES 7-9: Solid mass (max. dim. 1.1 cm, SUVmax:7.6) of the left lung (LUL) in a 72-yo male smoker’s case (40 pack-yrs).
