Abstract

A 35-year-old man noticed a tingling sensation and subsequent slight weakness in the distal part of the left lower extremities, which extended to the left thigh over the following 8 months, when he developed a urinary disturbance. He was admitted to a local hospital and diagnosed as having myelitis, because of the presence of a gadolinium (Gd)-enhanced lesion in the lumbar spinal cord corresponding to the tenth thoracic vertebra (Th10) level. The symptoms disappeared along with some residual sensory disturbance following intravenous administration of 1 g of methylprednisolone (IVMP) for 3 days. However, 4 months later, the patient gradually developed gait disturbance, dysuria, impotence, and fecal incontinence, and was admitted to our hospital in May 2001. A neurological examination revealed the presence of myeloradiculopathy causing a slight weakness in the left hamstring muscles, with positive Babinski and Lasegue signs on the same side. In addition, deep tendon reflexes were absent in the 4 extremities and vibration sense was moderately decreased in the lower extremities, though the results of electrophysiological tests of motor and sensory nerves were normal. A magnetic resonance imaging (MRI) study showed a Gd-enhanced les...Continue Reading
