Ossification in the cephalic attachment of the ligamentum flavum. An anatomical and CT study.
A review of 50 anatomical specimens and 100 routine CT scans of the chest and abdomen demonstrated that ossification in the cephalic attachment of the ligamentum flavum is a common anatomical finding, but not as common on CT. Examination of hospital charts and plain radiographs of 26 patients with such ossification suggests that it is probably a normal variant; there was no evidence that it is related to diffuse idiopathic skeletal hyperostosis (DISH) or inflammatory arthropathy. Marked ossification may cause or contribute to neurological symptoms.
