The lumbosacral trunk, typically comprised of part of the fourth lumbar ventral rami and the entirety of the fifth lumbar ventral rami, serves as a connection between the lumbar and sacral plexuses. Developmental differences underlie the variable relative contributions of L4 and L5 to the lumbosacral trunk. Herein, we report a rare case in which dissection of an adult male cadaver revealed no L4 contribution to the lumbosacral plexus. We discuss the surgical and clinical implications of such an anatomic variation.

INTRODUCTION: The accessory foramina could not be identified on some imaging modalities such as surface-rendered images. The purpose of this study was to investigate the ability of surface-rendered images in detecting these foramina.
MATERIALS AND METHODS: We analyzed 20 accessory mental foramina (AMF) in nine mandibles removed from cadavers with cone-beam computed tomography (CBCT) and assessed in surface-rendered images. All AMF were divided into three groups depending on their visibility.
RESULTS: Group 1 included AMF that were clearly visible as foramina, Group 2 were not clearly visible but could be recognized with concave parts, and Group 3 were not visible …
