Abstract
We report a patient who developed conversion disorder after spinal anesthesia. A 42-year-old woman was scheduled for hysteroscopic polypectomy under spinal anesthesia.However, since the spinal anesthesia did not attain adequate block level she was managed with general anesthesia. Although she had sufficient muscle strength of grasping and flexion and extension of knee joints and both feet shortly after emergency from anesthesia, she complained of loss of muscle power of four limbs and sensory impairment in lower limbs 4.5 h after spinal anesthesia. She claimed that the sensory impairment went up to the 3rd cervical dermatome; however, there was no respiratory or cardiovascular impairment. The symptoms spontaneously disappeared with time.
