Abstract

Lumbar disc herniation is the most common cause of radiculopathy. In most cases, the chief complaint is associated with radicular pain due to nerve compression on the herniated side. However, a radicular pain contralateral to the herniation side is an unusual finding rarely reported in the literature. Here, a case of right lower limb radicular pain in the presence of left extruded L4-L5 disc herniation is reported. Management of the patient is discussed in addition to a review of the literature regarding hypotheses on the mechanism of this unusual situation.
