A Case of Arnold Chiari Malformation Type 1 Admitted with Hypoesthesia

Arnold Chiari Malformation (ACM) type 1 is a clinical condition in which cerebellar tonsils extends to the upper cervical spinal canal through the foramen magnum. This form of ACM is considered to be adult type [1]. Older children or adults usually constitute patient population and patients are often asymptomatic [2]. Patients with ACM may present subtle and varying symptoms such as headache, extremity pain or weakness, vocal cord paralysis, vertigo, hypoesthesia. Nonspecific symptoms may cause delay in correct diagnosis [3]. Symptoms seen in ACM type 1 are well described in previous studies. In this case, a patient with ACM type 1 who applied with hypoesthesia is presented.
