title: Intramedullary spinal cord metastases in a patient with small-cell lung cancer.
abstract: We present the case of a 60-year-old male smoker with gait disturbance, lower limb sensory disturbance, and urinary difficulties of subacute onset and progressive course. He had been diagnosed 10 months earlier with limited stage small-cell lung cancer, had received chemotherapy, thoracic radiotherapy, and prophylactic cranial irradiation, and was in remission on follow-up. Examination revealed bilateral pyramidal tract signs, a T9 sensory level, and loss of vibration and position sense in the lower limbs. Gadolinium-enhanced MRI of the cervical and thoracic spinal cord revealed two enhancing intramedullary lesions consistent with metastases. Intramedullary metastases are exceedingly rare, accounting for only 3.4-6% of myelopathies in cancer patients, and they usually coexist with brain or leptomeningeal metastases. The presence of multiple metastases is even rarer, with two lesions found in only 10% of patients with intramedullary disease.
