The "Fisherman`s Waders" Sign on Bone Scan: A Case Report.

Fisherman`s Waders sign is caused by several medical conditions including venous thrombosis, portal hypertension and lymphoma. It is characterized by increased uptake of radiotracer in soft tissues below the mid-thorax level with normal tracer clearance above that level in bone scan. This case reports the Fisherman`s Waders sign in a patient with lymphoma complicated by Inferior Vena Cava (IVC) obstruction by the aid of CT scan and bone scan. Also, literature review of this rare sign is performed in this report. This sign can be found incidentally on bone scan and high level of awareness by the nuclear medicine physicians may alert the treating team for the underlying diagnosis.
