[Lumbosacral polyradiculomyelitis caused by cytomegalovirus in a patient with acquired immunodeficiency syndrome].

The case of a HIV positive patient with lumbosacral polyradiculomyelitis by cytomegalovirus (PLS-CMV) is presented. The patient was a homosexual male receiving maintainance treatment with foscarnet for previous corioretinitis by CMV who consulted for paraparesia and sphincter disorders of a 3 week evolution. Neutrophilic pleocytosis and high levels of glucose and proteins were observed on LCR and CMV isolated discarding other entities. The LCR normalized upon treatment with gancyclovir although serious residual paraparesia persisted. PLS-CMV is an infrequent entity of typical clinic and liquoral characteristics. Recognition of the same is important since favorable response depends on early anti-CMV treatment.
