Lumbar pedicular agenesis: Case report and a review of the literature

Abstract

Lumbar pedicular agenesis is a rare clinical and radiological finding. Therefore, it is commonly misdiagnosed, particularly in trauma cases, with the first case being reported by Hadley in 1946.Pedicle agenesis has specific radiographic features: a falsely appearing enlarged neural foramen; a dysplastic, dorsally displaced ipsilateral articular pillar and lamina; and a dysplastic ipsilateral transverse process.Computed tomography (CT) is the preferred diagnostic modality for pedicle agenesis and it is important to note that pedicle agenesis is a stable congenital anomaly. Typically, these patients do not exhibit neurological deficits and are managed conservatively or receive no treatment.In this case report, we will be reporting a case involving the absence of L5 left pedicle.
