18F-FDG PET/CT in Bilateral Breasts Metastasis From Ovarian Carcinoma

Ovarian carcinomas generally metastasize within the peritoneal cavity due to exfoliation of malignant cells from primary tumor. Metastasis to the breasts is an unusual event and may mimic primary neoplastic disease. Usually, breast metastasis presents as a single isolated, well-circumscribed soft tissue lesion, and serous papillary carcinoma is the most common type of ovarian tumor that can metastasize to the breast. Concurrent bilateral breast metastasis is rare event. We present a follow-up case of metastatic carcinoma ovary, demonstrating FDG-avid soft tissue density masses in the bilateral breast parenchyma along with bilateral axillary lymphadenopathy, biopsy of which revealed metastatic deposits from carcinoma ovary.
