...S. Sgouros Introduction: In recent years there has been renewed interest in the relation between Chiari I malformation and spinal cord tethering. Case Report: A 3-year-old girl presented with right leg pain. At spinal MR scan there was diastematomyelia with a bony peg at L1 and syringomyelia at T10...

...David Straus; Kimberly Foster; Frank Zimmerman; David Frim Background: Chiari I malformation (CM1) is characterized by impaired CSF flow through the foramen magnum. Dysfunctional autonomic cardiovascular regulation may result in syncope. Syncope may be the primary presenting symptom of CM1...

... for at least 1 year postoperatively. The patients were grouped into three subgroups: (a) group IA patients with a Chiari I malformation, (b) group IB patients with a Chiari I malformation and syrinx, and (c) group IC patients with a Chiari I malformation and hydrocephalus with or without an associated...

...Arnold H. Menezes The Chiari I malformation is associated with a hydromyelic cavity in 55–75% of patients. In the author’s series (1977–1991), hydromyelia occurred in 111 of 131 patients (85%). There were 35 children. Posterior fossa decompression with duraplasty and fourth ventricle...

...Virinder Nohria; Jerry Oakes We have reviewed the presentation, diagnosis, management, and outcome of 43 consecutive patients with the Chiari I malformation who were evaluated over a 12-year period and were managed by a single surgeon. The delay from the time of presentation to that of diagnosis...
