Polyostotic feet acrometastases from breast carcinoma demonstrated on [18F]FDG PET/CT imaging.

ABSTRACT

Acrometastases are rare. Less than 0.01% of patients have metastasis in the foot bone. Polyostotic metastasis in the foot is extremely rare. We report a 50-year-old woman who complained of progressive pain and swelling in the right foot after radical right mastectomy for 4 years. [18F]FDG PET/CT demonstrated multiple mixed bone destruction in the right foot with intense [18F]FDG PET/CT uptake. CT-guided calcaneus biopsy confirmed the diagnosis of metastatic breast carcinoma.
