INTRODUCTION: Truncal sensory level (TSL) is a localizing sign for spinal cord pathology. However, in rare instances, lesions higher up in the spinothalamic tract can cause TSL. CASE REPORT: A 26-year-old woman presented with numbness from waist down with a T7 TSL on examination with negative spine magnetic resonance imaging. Later, the patient developed the full picture of Guillain-Barré syndrome confirmed with electrophysiological testing. CONCLUSION: TSL can localize to the nerve roots and can be an early manifestation of Guillain-Barré syndrome.
