Intramedullary Spinal Cord Metastasis in Male Patient with Breast Cancer on 18F-FDG PET/CT: A Rare Finding.

Abstract

Intramedullary spinal cord metastasis in patients with breast cancer is exceptionally rare. A 57-y-old man with newly diagnosed breast cancer and regional and distant metastases presented with lower limb weakness. ¹⁸F-FDG PET/CT identified a tracer-avid intramedullary lesion in the thoracic spinal cord. Metastatic cells were confirmed by cerebrospinal fluid analysis. The patient's lower limb weakness resolved after radiotherapy to the spinal lesion.
