Isolated Cubital Node Metastasis in a Treated Case of Breast Carcinoma on 18 F-FDG PET/CT: A Rare Finding

Isolated cubital nodal metastasis is an extremely rare site of recurrence in posttreatment cases of breast carcinoma. A 37-y-old woman with breast carcinoma had a disease-free interval of 2 y. Follow-up ¹⁸F-FDG PET/CT showed a ¹⁸F-FDG-avid lesion in the proximal part of the right forearm, and PET/CT-guided fine-needle aspiration revealed metastatic carcinoma. With proven disease recurrence, the patient was scheduled for chemotherapy.
