title: [Value of US imaging following mastectomy].
abstract: OBJECTIVE
  To assess the value of US of the mastectomy site at the time of follow-up of the contralateral residual breast.
  
  
  METHODS
  Over a 5 year period, 251 patients with previous mastectomy underwent 505 unilateral mammographies with US of the mastectomy site. The time delay between imaging and mastectomy ranged between 1-15 years, with a mean of 7.5 years. Lesions at the mastectomy site were classified as follows: BIRADS 2 for a cyst or prominent edema, BIRADS 3 for a lymph node with preserved fatty hilum or mildly echogenic cyst, BIRADS 4 for well-defined hypoechoic lesions, and BIRADS 5 for ill-defined lesions.
  
  
  RESULTS
  None of the lesions classified as BIRADS 1, 2 or 3 was malignant. Eleven lesions were classified as BIRADS 4: 3 benign lesions, 7 malignant lesions, and 1 non-verified lesion. No lesion was classified as BIRADS 5.
  
  
  CONCLUSIONS
  Systematic US evaluation of the mastectomy site appears warranted since only 1 of 7 malignant lesions was clinically palpable prior to US whereas all were retrospectively palpable after US.
