Early detection of primary lesion with isolated axillary lymph node metastasis without any clinical or radiological evidence of tumour is still a pending issue. It is important to offer these patients a better management and survival. The definition of occult breast carcinoma is redefined as radiological diagnostic techniques progress.
We emphasize the contribution of whole-body fluorine-18 fluorodeoxyglucose positron emission tomography associated with computed tomography for staging, surgical approach and adjuvant treatments recommendations for these patients.
