A 44-year-old male patient suffering from sexual and voiding dysfunction did not exhibit any sensorimotor deficit except for a lax anal sphincter with loss of the bulbocavernosus reflex (BCR). The absence of both the electrically induced BCR and cortical evoked responses to stimulation of the dorsal penile nerve as well as partial denervation of the pelvic floor musculature suggested damage to the lower sacral roots. The site of the lesion as indicated by electrophysiological findings was confirmed by computerized tomography and magnetic resonance imaging. The operation revealed a lipoma involving a few cauda fibers which produced a distension in the region of the conus medullaris.
一名44岁患有性功能和排尿功能障碍的男性患者，除肛门括约肌松弛伴球海绵体反射（BCR）消失外，未表现出任何感觉运动功能缺损。电诱发的BCR以及对阴茎背神经刺激的皮层诱发电位均缺失，同时盆底肌肉组织部分失神经支配，提示骶神经低位受损。计算机断层扫描和磁共振成像证实了电生理检查结果所显示的病变部位。手术发现一个脂肪瘤累及几根马尾神经纤维，导致脊髓圆锥区域扩张。
