A 55 year old male presents with back pain and multiple epidural lesions in the lumbosacral spine found on surveillance magnetic resonance imaging. He was diagnosed with rectal cancer 13 years prior with multiple recurrences since that time. A computer tomography (CT)-guided fine needle aspiration (FNA) was obtained along with concurrent biopsy and touch preparations of a 12 mm soft tissue nodule within the neural foramen at the level of the second and third lumbar vertebrae.
