[Lumbosacral polyradiculomyelitis caused by herpes simplex virus (HSV) in a patient with AIDS].

To our knowledge this is the first description of lumbosacral polyradiculopathy produced by herpes simplex virus (HSV) without coinfection by cytomegalovirus (CMV) in a patient with HIV infection. The acute lumbosacral polyradiculomyelitis (ALP) in patients with AIDS is a well defined nosologic entity and classically associated to CMV infection. However, this pathology can be due to others etiologies as toxoplasmosis, syphilis, lymphoma, tuberculosis, cryptococcus, varicella-zoster virus fVZV), Epstein-Barr virus (EBT) and HSV associated CMV.
