A structural brain abnormality where brain tissue extends into the spinal canal, causing headaches and neurological symptoms.

Here's what these sources cover regarding Chiari malformation (note: "Budd-Chiari syndrome," a liver blood vessel condition, is a different, unrelated condition despite the similar name [4][9][12]).
Chiari malformation type I involves the lower part of the cerebellum (tonsils) extending below the skull base, which can compress the brainstem or contribute to fluid-filled cavities in the spinal cord (syringomyelia) [1][3][11]. Surgery (decompression, sometimes with tonsil reduction/resection) is a common treatment, and case reports describe good outcomes such as resolution of an extensive spinal syrinx and neurological recovery after surgery [3], and resolution of an unusual symptom—chronic cough—after decompression [6]. However, surgery carries risks: postoperative imaging often shows expected tissue swelling and small bleeding at the surgical site, though swelling extending beyond the expected area was linked to new neurological problems in some patients [1]. Research also suggests that severe crowding of fluid space around the brainstem/spinal cord junction on imaging before surgery is associated with a higher chance of needing repeat surgery and other complications afterward [11].

Spinal Deformity Characteristics Associated With Intraspinal Anomalies in a Population of Presumed Adolescent Idiopathic Scoliosis (AIS).
Intraspinal anomalies (IA) are reported to occur in 7% to 19% of patients undergoing surgery for adolescent idiopathic scoliosis (AIS). However, these studies have not focused on IA that require neurosurgical intervention and have not assessed whether deformity characteristics predict their underlyi…
Early Postoperative Magnetic Resonance Imaging Findings Related to Electrocauterization for Cerebellar Reduction During Chiari Decompression Surgery.
Cerebellar tonsillar reduction or resection can be performed as part of the surgical management of Chiari type 1 malformation when it is accompanied by symptomatic brainstem compression or syringomyelia. The purpose of this study is to characterize the early postoperative magnetic resonance imaging…
A rare case of near-complete resolution of extensive cervicothoracic syrinx following bilateral cerebellar tonsillar resection in Chiari malformation type I.
Chiari malformation type I (CM-I) often leads to syringomyelia (SM) through impaired cerebrospinal fluid (CSF) flow at the craniocervical junction, resulting in progressive neurological deficits. A 27-year-old woman presented with a 6-month history of severe occipital headaches, neck pain, bilateral…
Endovascular stenting of chronic retrohepatic inferior vena cava interruption in Budd-Chiari syndrome.
Budd-Chiari syndrome is a rare cause of hepatic venous outflow obstruction, with heterogenous etiologies. We report the case of a 35-year-old man with chronic, compensated Budd-Chiari syndrome due to retrohepatic inferior vena cava (IVC) occlusion, likely resulting from early-life thrombosis. Imagin…
"Intrapericardial Approach" for Venous Outflow Reconstruction in Living-Donor Liver Transplantation for Budd-Chiari Syndrome: Surgical Techniques and LongTerm Outcomes.
Unlike deceased-donor liver transplantation, living-donor liver transplantation (LDLT) for Budd-Chiari Syndrome (BCS) presents distinctive challenges in hepatic venous (HV)-outflow reconstruction because diseased HV-inferior vena cava (IVC) cannot be entirely replaced with healthy donor vessels. In…
Not all acute peripheral facial palsy in children recovers completely: A telediagnostic follow-up study.
Up to 30% of adults with peripheral facial palsy (FP) develop synkinesis, but it's incidence in children remains unclear due to limited long-term data. Children (<18 years) treated for acute peripheral FP at Jena University Hospital between 2009 and 2021 were screened in this cross-sectional study.…
Budd-Chiari Syndrome Due to Protein C Deficiency: A Case Report.
Budd-Chiari Syndrome (BCS), a rare vascular disorder of the liver characterized by obstruction of hepatic venous outflow, has an estimated prevalence of approximately 1 in 100,000 in the general population. Among its various etiologies, coagulation factor deficiencies are uncommon. This case, follow…
Cervicomedullary CSF space obliteration as a risk factor of reoperation in Chiari malformation type I.
In patients with Chiari malformation type 1 (CM1), it is unclear whether severe cervicomedullary CSF space crowding on preoperative MRI is associated with postoperative outcomes. We tested whether a binary classification scheme of cervicomedullary CSF space crowding (obliteration vs. non-obliteratio…
