ABSTRACT Involution of lactation is a physiological process. Rarely, it may be delayed and troublesome for the lactating woman. Though lactation-induced changes in breast are well known, morphological features of delayed involution are not clear.
We report a case of a 22-year-old lactating mother who presented with a painful, non-resolving breast mass 5 months after delivery. Clinically, it simulated an inflammatory carcinoma. Histopathology, however, revealed involuting lactational changes.
To the best of our knowledge, lactational involution with such a presentation has not been described in the English literature. The case needs to be reported so that this entity can be considered among the differential diagnoses of breast masses in a lactating patient.

    ABSTRACT: L’objectif de cette mise au point est de répondre à deux questions : l’innocuité de l’injection de chélate de gadolinium lors de l’allaitement ; l’intérêt ou non de réaliser une IRM mammaire chez la femme allaitante si l’on suspecte une tumeur du sein. Les publications anglo-saxonnes récentes sont en faveur d’un maintien de l’allaitement au décours de l’injection de gadolinium. En effet, le passage du produit de contraste dans le lait maternel est infime, et bien inférieur au seuil recommandé en pédiatrie chez le nourrisson. Cependant, la suspension de la lactation dans les 24 heures qui suivent l’injection de chélate de gadolinium reste préconisée en France. La littérature est pauvre en ce qui concerne l’apport de l’IRM durant la lactation, mais l’ensemble des données ébauchent l’idée que l’IRM est contributive, malgré les modifications physiologiques de la glande durant cette période. En effet, toutes les lésions ont été visualisées et classées correctement selon la classification BIRADS de l’ACR1. En revanche, la sémiologie est particulière et à connaître.

    ABSTRACT: The paper tries to answer two questions: the safety of the injection of gadolinium during breastfeeding; the value of a breast MRI in the nursing mother if breast cancer is suspected. Recent Anglo-Saxon publications are in favour of continued breastfeeding following the injection of gadolinium. In fact, only a minute quantity of contrast product passes into the mother's milk, much less than the threshold recommended in paediatrics in the infant. However, a suspension of lactation for 24h after the injection of gadolinium chelate is still recommended in France. The literature is poor as regards the contribution of the MRI during lactation, although the data indicates that the MRI is contributory, in spite of the physiological changes in the breast during this period. In fact, all of the lesions have been visualised and correctly classified according to the BI-RADS classification by the ACR(1). However, the semiology is specific and has to be known.
