Hajdu-Cheney syndrome is a rare congenital disease with acro-osteolysis, osteoporotic changes of the spine and long bones of extremities and marked basilar invagination with an unusually deformed skull. Magnetic resonance imaging of a 32-year-old male revealed the deformed skull and almost horizontal basal angle and the elongated and upwardly shifted brain stem caused by the tip of the odontoid process of the second cervical vertebra invaginating the base of the skull. In addition there were atrophic pituitary gland, widely open sella turcica and symmetrical fluid collections along the optic nerve sheath.
哈伊杜－切尼综合征是一种罕见的先天性疾病，其特征为肢端骨质溶解、脊柱和四肢长骨的骨质疏松改变以及明显的颅底陷入症伴颅骨异常变形。一名32岁男性的磁共振成像显示颅骨变形、基底角几乎呈水平位，以及第二颈椎齿突尖端陷入颅底导致脑干拉长并向上移位。此外，还存在垂体萎缩、蝶鞍扩大以及沿视神经鞘的对称性液体积聚。
