Abstract
Identifying osseous metastases by imaging is essential and may be challenging in patients with lobular breast cancer. We present a case of a 66-year-old woman with lobular breast cancer who underwent 18F- fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) for staging purposes. 18F-FDG PET/CT reveals minimal FDG uptake in the primary tumor cells. Prominent sclerotic lesions with low FDG avidity are seen in the spinal and pelvic bones. The subsequent Tc-99m methylene diphosphonate bone scan is unremarkable. The magnetic resonance multiple imaging (MRI) reveals bone metastases. MRI may be beneficial in invasive lobular carcinoma. MRI facilitates improved metastatic evaluation, especially in bone-only and bone-predominant metastatic malignancies, when assessment with 18F-FDG PET/CT may be difficult and constrained.
