Large PLV can cause spinal stenosis, and small PLV can be mistaken as intraspinal disc herniation. Although the clinical presentations were similar, the surgery was quite different. We had experienced preoperative misdiagnosed cases and the surgery could not be finished. Therefore we analyzed the imaging features of PLV in 34 patients in order to prompt appropriate preoperative diagnosis and surgical planning. ? 2012 Elsevier Inc.[SDGs]SDG3Clinical presentations; Imaging features; Intravertebral disc herniation; Limbus fragment; Posterior limbus vertebra; Preoperative diagnosis; Spinal stenosis; Surgical planning; Surgery; Musculoskeletal system; analgesic agent; adolescent; adult; aged; article; clinical article; clinical feature; computer assisted tomography; diagnostic error; differential diagnosis; female; human; image analysis; intervertebral disk hernia; intervertebral diskectomy; laminectomy; low back pain; male; nuclear magnetic resonance imaging; physiotherapy; picture archiving and communication system; posterior limbus vertebra; preoperative evaluation; priority journal; retrospective study; spine disease; spine radiography; spine surgery; treatment planning; Adolescent; Adult; Aged; Female; Humans; Intervertebral Disc Displacement; Magnetic Resonance Imaging; Male; Middle Aged; Reproducibility of Results; Sensitivity and Specificity; Spine; Tomography, X-Ray Computed; Young Adultjournal article10.1016/j.clinimag.2012.01.031231540122-s2.0-84869121102
