Arnold – Chiari malformation is a rare congenital disease characterized by displacement of the brain and its structures into the cervical canal area due to the development of the posterior skull. In the practice of neurologists and neurosurgeons, each clinical case of Arnold – Chiari malformation is a difficult task for the diagnosis, treatment and relief of the patient's symptoms. Goal. Description of a clinical case in a patient with Arnold – Chiari malformation to study the features of diagnosis, treatment and intervention results in the practice of neurologists and neurosurgeons. Materials and methods. The article describes in detail the clinical case of a patient with Arnold – Chiari malformation, including anamnesis data, examination results, medical measures taken and treatment results. Results. The patient, who was experiencing severe neurological symptoms,
including dizziness, nausea, speech and coordination disorders, received treatment with good results. After surgery, there was a regression of symptoms, restoration of cerebrospinal fluid outflow and clinical improvement of the condition. Conclusion. Surgical intervention by decompression and laminectomy has shown effectiveness in the treatment of columbian hypertension syndrome with omission of the cerebellar tonsils in this patient, which led to an improvement in her neurological status and a decrease in clinical
manifestations. The study of the clinical case of a patient with Arnold – Chiari malformation demonstrates the importance of timely diagnosis, expert advice and the right choice of treatment strategy in the practice of neurologists and neurosurgeons to achieve successful results and improve the quality of life of patients.
