A Case of Arnold Chiari Malformation Type-1 Diagnosed Incidentally After Head Trauma.

Arnold-Chiari Malformation is characterized by herniation of the tonsils of the cerebellum through the foramen magnum into the cervical spinal canal. The etiology of Arnold-Chiari Malformation remains unclear. Malformation may be accompanied by intracranial or extracranial developmental defects such as hydrocephalus, syringomyelia, encephalocele. Different classifications are made according to the accompanying malformation. Arnold-Chiari Malformation can remain asymptomatic during childhood or manifest with neurological symptoms such as headaches. Since there are many different complaints and findings in this malformation, patients present to various medical units. We present a patient who presented to the emergency department with recurrent vomiting after head trauma and was found to have Arnold-Chiari Malformation Type-1 incidentally. [ABSTRACT FROM AUTHOR]
