The recent developments in Computed Tomography (CT) and Magnetic Resonance
Imaging (MRI) allow an accurate analysis of the anatomical structures of th
e lateral recess and of the neural foramen (vertebral body, pedicle, zygapo
physeal joints, ligamentum flavum, intervertebral disk) and their contents
(spinal ganglion, nerves roots, foraminal veins, surrounding fat). The aim
of this study is 1) to describe the normal anatomy and Variants of the late
ral recess and of the lumbar neural foremen, and 2) to present the main dis
eases involving this anatomical area.
