Introduction: There are four types of Chiari malformations described in the literature. Due to the fact that it is a common finding in the general population (true Chiari being present in 0,75% of the population), Chiari 1 malformation was also called Chiari anomaly. Material and methods: In the last 5 years 17 patients with Chiari I malformation have been treated in our clinic. There were 12 w...

INTRODUCTION 
 Pseudotumor cerebri (PTC) patients exhibit clear clinical signs and symptoms of higher intracranial pressure (ICP) without ventricular enlargement or mass lesions. The clinical picture of patients with PTC can sometimes be similar to that of Chiari Malformation type I (CMI). There is some evidence that Chiari I malformation and PTC may coexist, which raises the question of whethe...

A rare case of haemangiomatous malformation affecting the mediastinum, spleen, kidney, and liver is described. The literature concerning mediastinal haemangiomas is discussed.

Myelomeningocele (MMC) is the most frequent congenital defect of the central nervous system for which there is no satisfactory alternative to postnatal treatment. On the contrary prenatal MMC surgery is conducting before birth and is aimed at protecting from Chiari II malformation. The main goal of fetal MMC repair is to improve development and life quality of children with Chiari II malformati...

Chiari malformation describes a group of structural defects of the cerebellum, characterized by brain tissue protruding into the spinal canal. Chiari malformations are often associated with myelomeningocele, hydrocephalus, syringomyelia, and tethered cord syndrome. Although studies of etiology are few, an increasing number of specific genetic syndromes are found to be associated with Chiari mal...

Chiari malformation type 1 is a heterogeneous disease characterized by cerebellar tonsillar herniation through the foramen magnum. Symptomatology is diverse, and diagnosis and treatment are controversial. Some evidence suggests the presence of a genetic component to the disease. However, the specific genetic factors involved remain relatively unknown. Previous reviews have broadly addressed dif...

Chiari II malformations and holoprosencephaly have been considered to be brain malformations that differ with respect to teratogenic insult, embryologic mechanism, and morphology. We herein describe coexistent Chiari II malformation and holoprosencephaly that occurred in a viable infant. A review of the literature regarding Chiari II malformations and holoprosencephaly suggests that a disturban...

INTRODUCTION Trigeminal neuralgia (TN) is characterised by recurrent episodes of sudden, intense, usually unilateral, lancinating pain confined to the distribution of one or more branches of the trigeminal nerve. It is most commonly associated with compression of the trigeminal nerve root by an artery or vein, which is thought to lead to irritability of the nerve root due to demyelination and r...

Acute delirium can occur in a variety of states including migraine, l head trauma,2 nonconvulsive status epilepticus,3 and cerebral infarction.4 Acute delirium accompanied by migrainous headache is much more common in children than adults and is termed acute confusional migraine.s In 1883 John Cleland, a British poet and anatomist, first described the abnormality of the brainstem and cerebellum...

OBJECT Surgery for Chiari malformation Type I (CM-I) is one of the most common neurosurgical procedures performed in children, although there is clearly no consensus among practitioners about which surgical method is preferred. The objective of this meta-analysis was to compare the outcome of posterior fossa decompression with duraplasty (PFDD) and posterior fossa decompression without duraplas...
