title: Schizophrenic psychosis with a tendency of systemic ossification.
abstract: We report here a case of schizophrenic psychosis with a tendency of systemic ossification. Upon further examinations, she exhibited ossification of the spinal ligament (diffuse idiopathic skeletal hyperostosis, DISH) resulting from a coappearance of ossification of the posterior longitudinal ligament (OPLL), ossification of the yellow ligament (OYL) and ankylosing spinal hyperostosis (ASH). There have been a very few reports where a tendency of hyperostosis was observed for ossification of the spinal ligaments such as OPLL, OYL and ASH. In addition, she exhibited hyperostosis frontalis interna (HFI). It appears in this case that both DISH and HFI resulted from similar ossification and exhibited respective clinical symptoms. Although it is thought that these diseases resulted from some metabolic abnormality, no abnormality was detected.
