A 17 year old female with widely metastatic paraganglioma underwent CRYO and radiofrequency ablation (RFA) of multiple osseous lesions to palliate symptoms of catecholamine excess and achieve local control. Pre-ablation PET/MRI demonstrated a fluorodeoxyglucose (FDG) avid lesion involving the supraacetabular left ilium (A). Two cryoablation needles were placed into the lesion and the iceball encompassed the metastasis (B). At 20 months post procedure, PET/CT demonstrated no evidence of residual hypermetabolic paraganglioma in the supraacetabular left ilium (C). Additionally, following ablation her symptoms of catecholamine excess improved and she reduced the dose of her chronic adrenergic blockade.
