A rare case of arteriovenous malformation at the cervicomedullary junction is reported. A 72-year-old man developed symptoms of total transection of the upper cervical cord without evidence of subarachnoid hemorrhage. The arteriovenous malformation had an intramedullary nidus with an aneurysmal dilatation at the C-1 level. This lesion was diagnosed by magnetic resonance imaging and confirmed at autopsy. The neurological symptoms may have been due to compression of the spinal cord by the intramedullary lesion, followed by degeneration and necrosis. The usefulness of magnetic resonance imaging in the neuroradiological diagnosis is particularly emphasized.
报告了一例罕见的延髓颈髓交界处动静脉畸形病例。一名72岁男性出现上颈髓完全横断症状，但无蛛网膜下腔出血迹象。动静脉畸形在髓内有一个病灶，在C-1水平有动脉瘤样扩张。该病变通过磁共振成像诊断，并在尸检时得到证实。神经症状可能是由于髓内病变压迫脊髓，随后发生变性和坏死。特别强调了磁共振成像在神经放射学诊断中的作用。
