Chiari malformations are anatomic anomalies that comprise a broad spectrum of neurologic conditions. The most common malformation, a Chiari type I malformation, can present with a variety of signs and symptoms, most frequently an occipital Valsalva-induced headache. Cranial and spinal magnetic resonance (MR) imaging is used to identify the degree of tonsillar descent and document the presence of syringohydromyelia. The advent of cine-MR flow imaging (cine as in "cinema") has provided new insight as to the dynamic process involved in the evolution of this pathophysiology. This article reviews the neuroimaging of this fascinating disorder.

Introduction: Posterior vault distraction osteogenesis (PVDO) allows significant increase in intracranial volume but is associated with complications including cerebrospinal fluid (CSF) leaks, infection and device failure. The authors outline their outcomes over 12 years and the impact of PVDO on pre-existing Chiari malformation type 1 (CM).
Method: Retrospective review of all PVDOs in our unit over a period of 12 years from 2011 to 2023.

Background: Postoperative subdural hematoma (SDH) typically presents with headache, impaired consciousness, hemiplegia, gait disturbance, and aphasia but can also present with visual impairment.
Observations: A 52-year-old woman diagnosed with Chiari malformation type I and syringomyelia underwent foramen magnum decompression. Cerebrospinal fluid was lost due to arachnoid injury during the procedure.

Background And Objective: Chiari I Malformation-associated syringomyelia (CM) and idiopathic syringomyelia (IS) are often confused together. They require different diagnostic approach and treatment modalities; it is important to distinguish between the two. We aimed to evaluate the radiological and morphologic characteristics of CM and IS in adult and pediatric patients in Pakistani population.

Purpose: Pediatric hydrocephalus imposes a significant clinical and financial burden in developing countries. Traditional treatment by ventricular shunting in this setting suffers a high rate of shunt infection and malfunction. This study aims at assessing the efficacy and safety of endoscopic third ventriculostomy (ETV), either alone or combined with choroid plexus cauterization (CPC), for preventing shunt dependence in pediatric hydrocephalus within a healthcare setting of a tertiary hospital in Egypt.

Chiari malformation is a condition involving caudal descent of the hindbrain which herniates the cerebellar tonsils through the foramen magnum. The purpose of this study was to quantify auditory deficits in an affected individual and to explore the hypothesis that cerebellar malformation specifically disrupts binaural processing. We present audiometric, electrophysiologic, imaging and auditory perceptual findings for a 17-year-old female with Chiari 1 malformation and for a cohort of 35 hearing- and age-matched controls.
