Spinal X-ray and sagittal MR image of the cervical spine of a 19-year-old male patient with neck pain and restricted neck motion. X-ray (a) shows a lesion in the C6 associated with severe vertebral collapse. The lesion shows slight hypointensity on T1WI (b), hyperintensity on T2WI (c), and hyperintensity on fat-saturated T2WI (d, e), associated with obvious marrow and soft tissue edema, and prevertebral and epidural soft tissue extension. The diagnosis of LCH was confirmed by pathology after surgery (pathological slice HE × 200) (f)
