A 73-year-old female was admitted to our hospital due to sudden onset of lower limb weakness and gait disturbance. Chest radiograph revealed a tumor in the left lung, suggesting spinal cord metastasis, but an MRI showed no spinal cord signal abnormalities. After transbronchial biopsy, a diagnosis of small cell lung cancer was made. Neurological examination and a peripheral nerve conduction study indicated paraneoplastic neurological syndrome with myelitis and sensory axonal neuropathy. As the lung tumor regressed after chemoradiotherapy, neurological symptoms improved. Serum anti-CV-2 and anti-SOX-1 antibodies, which were positive before treatment, changed to negative.
