  Abstract 

Gestational or pregnancy-associated breast cancer is defined as breast cancer that is diagnosed during pregnancy, in the first postpartum year, or any time during lactation. We report rare imaging findings of a breast cancer seen on fluorodeoxyglucose-positron emission tomography/computed tomography (FDG PET/CT) study in a 32-year-old lactating woman. The FDG PET/CT study demonstrated uptake in the soft tissue lesion noted in the right breast corresponding to primary lesion and multiple nodes in bilateral axilla, right supraclavicular and mediastinum. In addition, there was FDG tracer uptake in both the breast parenchyma-related to breast feeding. This case illustrates the first case of breast cancer in a lactating woman detected by FDG PET/CT.

  Introduction Top


The incidence of pregnancy associated breast cancer (for the prenatal to postpartum period) is approximately 15-35/100,000 deliveries, with fewer breast cancer cases diagnosed during pregnancy than during the first postpartum year. [1] Women with a genetic predisposition to breast cancer may be over represented among pregnant women with cancer, although the available evidence is limited. [2] There are no previous reports of F-18 fluorodeoxyglucose-positron emission tomography/computed (FDG PET/CT) in lactating women with breast cancer.


  Case Report Top


A 32-year-old female patient who had delivered a child 2 months back and breast feeding presented with lump in the right breast. She underwent an excision biopsy of the breast lump which showed invasive ductal carcinoma. As a part of evaluation, she was subjected to a PET/CT scan which was done on a hybrid scanner after injection of approximately 10 mCi of F-18 FDG. Maximum intensity projection image [Figure 1], right down] showed diffusely increased FDG uptake in both the breasts due to lactation and intense FDG uptake noted in right breast mass lesion. CT, fused PET/CT and PET transaxial image [Figure 1], right and left] at the level of breast shows increased FDG uptake in bilateral breast parenchyma and multiple nodes. As PET/CT scan confirmed metastatic involvement of multiple nodes, patient underwent chemotherapy.

  Discussion Top


Breast cancer is one of the most common cancers in nonpregnant and pregnant women. [1] Up to 20% of breast cancers in women under age 30 are pregnancy-associated, but fewer than 5% of breast cancers diagnosed in women under age 50 are detected during pregnancy or in the postpartum period. [2] FDG PET/CT in breast cancer imaging has an adjunctive role in the detection of loco-regional recurrence or distant metastases in locally advanced breast cancer when results of other standard imaging techniques are equivocal or suspicious. [3] Increased FDG uptake in lactation is thought to be the result of uptake of plasma glucose for milk production and increased activity of the ductal muscles. [4],[5],[6] Hicks et al. [7] described that most of patients who were breast-feeding an infant before PET scanning had diffuse and symmetric uptake in the breasts. Asymmetric breast uptake in lactating women and in a patient with hydatid cyst has been described. [8],[9] To the best of our knowledge, this is the first case report of breast cancer with lactating breast uptake detected on FDG PET scan. FDG uptake pattern have been useful in predicting the benign or malignant nature of nodes. In our case, as PET study revealed multiple nodal metastases, patient was subjected to chemotherapy. Our case, thus, illustrates that FDG PET/CT is an important imaging modality for the detection and accurate staging and restaging of breast cancer, and to decide upon appropriate treatment even in a lactating women.
