Ischaemic myelopathy secondary to disseminated intravascular coagulation in AIDS.
A 39-year-old patient with AIDS presented with a rapidly progressive myelopathy with a partial Brown-Séquard syndrome. He died, 9 weeks after onset of the first neurological signs, from diffuse encephalopathy. Neuropathological examination revealed multiple, usually small, frequently haemorrhagic, infarcts or various ages and numerous fibrin thrombi in medium and small penetrating vessels and capillaries of the brain and spinal cord, characteristic of disseminated intravascular coagulation. There were no inflammatory changes. Immunohistochemical studies for human immunodeficiency virus, cytomegalovirus, varicella zoster virus, herpes simplex virus type 1 and type 2 were negative. Ischaemic spinal cord lesions due to disseminated intravascular coagulation may represent an unusual cause of focal, non-inflammatory, non-tumoral, myelopathic syndrome in AIDS.
