Recurrence in a reconstructed breast.The patient had right mastectomy and reconstruction with an implant and LD flap 3 years ago. She presented with a vague palpable lump in her right breast. PET scan showed an fluorodeoxyglucose avid mass (arrows) in the lateral half of the reconstructed breast. The implant (asterisks) was pushed medially by the mass. Note the absent right LD muscle from its expected location compared with the normal left LD muscle (dashed arrows). The mass was histologically proven to be a sarcoma. LD = latissimus dorsi
