척수 뒤기둥을 침범한 간성 척수병증

Abstract

Hepatic myelopathy is a rare neurological complication of chronic liver disease, and is characterized by a progressing spastic paraparesis without any sensory loss. However, a few recent reports suggest that involvement of the sensory system is also possible in hepatic myelopathy. We present a patient with hepatic myelopathy, who had impaired proprioception and a delayed cortical response of somatosensory evoked potentials. This supports the hypothesis that hepatic myelopathy may involve the sensory system as well as the motor system.
