Abstract:Skull base invagination is a common malformation in the craniocervical region.It refers to the bone tissue of skull base surrounding the occipital foramen invaginated into the cranial cavity,leading to stenosis of occipital foramen,causing brainstem,medulla oblongata and cervical spinal cord,cerebellum,cranial nerve and peripheral blood vessels to be compressed,and then clinical manifestation will appear.Currently,its pathogenesis has not been clarified,but abnormal embryonic development is mostly considered.There are many types of classifications.It can be divided into primary disease and secondary disease according to the etiology.The disease has a trait of long incubation period and strong concealment.There may be no obvious symptoms at the initial stage of the disease.With the increase of age,the clinical symptoms occur after the bone structure changes.The clinical manifestations are mainly nerve compression symptoms,and characteristic appearance can be accompanied.Currently,the diagnosis mainly depends on imaging findings such as plain radiographs,CT and magnetic resonance imaging (MRI).For patients with suspected skull base invagination,MRI should be preferred.If the patient does not have obvious clinical symptoms,conservative treatment and regular follow-up visits are necessary.However,when clinical symptoms occur,surgery must be performed as soon as possible to alleviate the compression.In this paper,we shared a case of misdiagnosis with dysphagia as the first symptom.Through a retrospective study of recent years′ knowledge related to skull base invagination,this misdiagnosis is analyzed and discussed to deepen the understanding of the skull base invagination and improve clinical vigilance.Hopefully early diagnosis and early treatment of the disease can be achieved.
