Abstract

Soft tissue aneurysmal bone cyst is very rare. Herein, we report FDG PET/CT findings of aneurysmal bone cyst in a 19-year-old man. On conventional image, it presented as a paravertebral soft tissue mass with heterogeneous enhancement and rim eggshell-like calcification. On PET/CT, this solitary lesion had intense FDG uptake with an SUV max of 10.33. The final pathology supported a diagnosis of aneurysmal bone cyst. Our case suggests that soft tissue aneurysmal bone cyst should be regarded as a differential diagnosis of solitary paravertebral mass with intense FDG uptake.
