Findings: 1. Increased FDG uptake within a soft tissue density between the left scapula and chest wall just inferior to the scapula (Figure 2).

2. Increased FDG uptake within the left axillary lymph node (Figure 3).
Diagnosis: Elastofibroma.
General Discussion: Elastofibroma is a benign connective tussue tumor mostly seen in middle-aged women.  Their characteristic location (usually located between the scapula and chest wall along the inferior aspect of the scapula) is helpful in diagnosis.  Classic CT/MRI appearance is a soft tissue mass with interspersed strands of fat (as seen in this case).  Increased FDG uptake has been reported with elastofibroma (Reference 1). 

Increased uptake in the left axillary lymph node was felt to be secondary to infiltration of the tracer in the antecubital fossa.  The lymph node had been stable in size over the past 1-2 years.
