説明

We report two cases of spinal arteriovenous malformations presenting with anterior spinal artery syndrome. Case 1 was a 40-year-old woman. She was admitted to this hospital because of numbness in the bilateral lower extremities and severe lumbago, which were suddenly manifested on exertion. Case 2 was a 19-year-old man. He was transmitted to this hospital because of precordial oppression and complete motor paraplegia, which were manifested suddenly at rest. In both cases, spinal palsy, dissociated sensory disturbance, and bowel and bladder dysfunctions were observed clinically, and MRI of the spinal cord demonstrated findings suggestive of spinal ischemia and/or infarction in the anterior region of the spinal cord. On the basis of these findings, we diagnosed the two cases as anterior spinal artery syndrome. Conservative treatments were not effective, and both patients developed sensory disturbances. MRI of the spinal cord was performed a second time, and it demonstrated tortuous vascular lesions at the dorsal site of the spinal cord by the flow void phenomenon. Spinal angiography revealed arteriovenous malformations (dural type in case 1, and intradural type in case 2). We consider both cases to be intersting not only with respect to the pathoetiology of anterior spinal artery syndrome caused by spinal arteriovenous malformations, but also with respect to the results of various neuraradiologic examinations, such as MRI of the spinal cord and spinal angiography.
