Arnold-Chiari malformation is a disorder of embryologic development. In Type I, there is cerebellar displacement into the spinal canal, but hydrocephalus and syringomyelia are variable. Type II usually is manifested by severe hydrocephalus and myelomeningocele in infancy. Type I malformations may pose diagnostic challenges because they often produce bizarre and vague symptoms. A careful history and physical examination, coupled with neurologic testing, especially magnetic resonance imaging, will lead to the correct diagnosis.
阿诺德-奇阿利畸形是一种胚胎发育障碍性疾病。I型表现为小脑疝入椎管，但脑积水和脊髓空洞症情况不一。II型通常在婴儿期表现为严重脑积水和脊髓脊膜膨出。I型畸形可能带来诊断挑战，因为它们常产生怪异且模糊的症状。详细的病史和体格检查，再结合神经学检查，尤其是磁共振成像，将有助于做出正确诊断。
