Research process, recap, and prediction of Chiari malformation based on bicentennial history of nomenclature and terms misuse. Neurosurg Rev 2023; 46:316.

Abstract
There is an absent systematic analysis or review that has been conducted to clarify the topic of nomenclature history and terms misuse about Chiari malformations (CMs). We reviewed all reports on terms coined for CMs for rational use and provided their etymology and future development. All literature on the nomenclature of CMs was retrieved and extracted into core terms. Subsequently, keyword analysis, preceding and predicting (2023-2025) compound annual growth rate (CAGR) of each core term, was calculated using a mathematical formula and autoregressive integrated moving average model in Python. Totally 64,527 CM term usage was identified. Of these, 57 original terms were collected and then extracted into 24 core-terms. Seventeen terms have their own featured author keywords, while seven terms are homologous. The preceding CAGR of 24 terms showed significant growth in use for 18 terms, while 13, three, three, and five terms may show sustained growth, remain stable, decline, and rare in usage, respectively, in the future. Previously, owing to intricate nomenclature, Chiari terms were frequently misused, and numerous seemingly novel but worthless even improper terms have emerged. For a very basic neuropathological phenomenon tonsillar herniation by multiple etiology, a mechanism-based nosology seems to be more conducive to future communication than an umbrella eponym. However, a good nomenclature also should encapsulate all characteristics of this condition, but this is lacking in current CM research, as the pathophysiological mechanisms are not elucidated for the majority of CMs.

Tectal glioma presenting with clinical triad of obesity, amenorrhea and central cord syndrome with radiological pentad of hydrocephalus, empty sella, suprapineal diverticula, Chiari and syrinx. Childs Nerv Syst 2017; 33:385-387. [PMID: 27757566 DOI: 10.1007/s00381-016-3266-0] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2016] [Accepted: 10/05/2016] [Indexed: 10/20/2022]
Abstract
BACKGROUND Tectal gliomas (TG) are slow-growing tumors and generally present with features of increased intracranial pressure. CASE DESCRIPTION We describe an unusual case of a young girl who presented with clinical triad of obesity, primary amenorrhea and central cord syndrome. The radiology unveiled a pentad of hydrocephalus, empty sella, suprapineal recess diverticulum, secondary Chiari malformation and cervical syringomyelia, masking a relatively obscure tectal plate glioma. She was subjected to endoscopic third ventriculostomy (ETV). All of her symptoms improved after ETV and the tumor is being followed up. The possible pathogenesis of such a highly atypical clinico-radiological presentation is described. CONCLUSION This unusual syndromic presentation of tectal glioma without clinical features of increased intracranial pressure is probably due to increased compliance of third ventricular walls, and is relieved with ETV.

Abstract
It is very rare that a foramen magnum arachnoid cyst induces compression of the spinal cord and syringomyelia, and currently there are few treatment experiences available. Here we reported the case of a 43-year-old male patient who admitted to the hospital due to weakness and numbness of all 4 limbs, with difficulty in urination and bowel movement. MRI revealed a foramen magnum arachnoid cyst with associated syringomyelia. Posterior fossa decompression and arachnoid cyst excision were performed. Decompression was fully undertaken during surgery; however, only the posterior wall of the arachnoid cyst was excised, because it was almost impossible to remove the whole arachnoid cyst due to toughness of the cyst and tight adhesion to the spinal cord. Three months after the surgery, MRI showed a reduction in the size of the arachnoid cyst but syrinx still remained. Despite this, the symptoms of the patient were obviously improved compared to before surgery. Thus, for the treatment of foramen magnum arachnoid cyst with compression of the spinal cord and syringomyelia, if the arachnoid cyst could not be completely excised, excision should be performed as much as possible with complete decompression of the posterior fossa, which could result in a satisfying outcome.
