Figure 8. PET

To convince the surgeons that the mass was indeed likely to be neoplastic, PET scan was performed. PET showed increased tracer uptake within the mass, consistent with a metabolically active lesion. The presence of uptake on the PET scan excluded simple blood clot as the etiology of the lesion.

The bladder is filled with tracer, and the brain positivity represents normal metabolic activity.
