title: [A case of primary central nervous system lymphoma with the onset of impotence].
abstract: A 51-year-old man suffered from impotence for 10 months. Five months before he developed difficulty in urination and walking because of his both leg weakness. He was admitted to the hospital because of urinary incontinence, paraplegia and occipital headache. Neurologic examination revealed neck stiffness and Lhermitte's sign. The cranial nerves were intact with the exception of choked disc. He had weakness of lower extremities and right arm, and sensory loss on the right side including face. The plantar responses were extensor bilaterally. MR images revealed diffuse swelling in the cervical and thoracic spinal cord on a T 1-weighted image without enhancement by Gd-DTPA and diffuse high intensity of the spinal cord on a T 2-weighted image. MR image of the brain revealed the low intensity in the left temporal and occipital lobe with slightly enhancement by Gd-DTPA, the high intensity in the left temporal and occipital lobe white matter on a T 2-weighted image. Diagnosis of malignant lymphoma (B cell type) was made by brain biopsy. Combined chemotherapy was performed and his symptoms resolved and the lesions on MRI disappeared. The number of cases of primary spinal intramedullary malignant lymphoma was very rare and the majority of the cases had weakness or sensory impairment in the lower extremities in the initial symptoms. This is the first case which had impotence as the initial symptom. In addition, it must be taken into consideration of this disease when the patient has myelopathy with unknown etiology.
