Case Presentation

A 38-year-old woman presented with a 1-week history of progressive bilateral leg weakness, numbness below the chest, and urinary retention. Neurologic examination revealed mild to moderate weakness and hyperreflexia of the arms and legs bilaterally, a discrete sensory deficit at C7, and diminished rectal tone. MRI of the cervical spine with and without contrast was performed (Figure 1), including gadolinium postcontrast sagittal T1-weighted, sagittal T2-weighted, axial noncontrast T1-weighted, and axial T2-weighted images.

Family history is positive for cancer in 2 first-degree relatives at an early age.

Which of the following is a next reasonable step?

  1. Perform CT-guided biopsy of the lesion

  2. Perform MRI-guided biopsy of the lesion

  3. Perform a spinal tap for CSF analysis

  4. Give empiric radiotherapy

  5. Begin anticoagulation
