[Lesions of the spinal cord and spinal roots in human immunodeficiency virus infection].
Spinal cord lesions, although far less frequent than brain lesions, are not uncommon in AIDS. Almost all diffuse or multifocal pathological processes involving the central nervous system and/or leptomeninges may also affect the spinal cord. However, some of them involve it predominantly causing specific, clinically overt, myelopathic diseases. The most characteristic of these is vacuolar myelopathy which usually manifests as progressive spastic ataxia. Its incidence varies in different pathological series and its pathogenesis is still controversial. Acute meningomyeloradiculitis in AIDS patients presents a remarkably uniform and distinct clinical and cerebrospinal fluid profile although they might be due to various causes including cytomegalovirus infection, syphilis, mycobacterial infection or leptomeningeal malignancy. Tumoral focal syndromes have exceptionally been recorded due to epidural lymphomas, intraspinal gliomas or toxoplasma abscesses. Spinal cord ischemic lesions have been documented in two cases: they were related to inflammatory lesions of the blood vessels in one case and to diffuse intravascular coagulation in the other. An ascending myelitis syndrome, secondary to spinal cord infection by both herpes simplex virus type 2 and cytomegalovirus, without significant vasculitis has also been reported.
