Solitary Axillary Lymph Node Metastasis From Ovarian Cancer on 18F-FDG PET/CT

Abstract Solitary axillary lymph node metastasis from ovarian cancer is rare. A 74-year-old woman who had undergone hysterectomy and bilateral salpingo-oophorectomy for ovarian cancer 2 years ago presented to our hospital with enlarged axillary lymph node. 18 F-FDG PET/CT revealed left axillary lymphadenopathy with an SUV max of 8.92. The postbiopsy pathology confirmed metastasis of poorly differentiated ovarian adenocarcinoma. This case highlights the need to consider ovarian cancer metastasis in cases of solitary axillary lymphadenopathy with intense FDG uptake, especially in patients with a recent history of ovarian cancer.
