Outcomes of Chiari malformation III: A review of literature

Chiari III malformation in a neonate

“…Twenty-one of these cases were either lost to follow-up or their outcome was not mentioned in the literature. Of the rest, 11 cases had a good outcome with minimal or no neurological deficits, 12 cases showed mental retardation with or without global developmental delay, 3 developed infantile spasms or seizures, 2 required continued ventilatory support, 1 developed CNS infection, 1 was stillborn, 1 developed abnormal movements and 7 patients passed away, either due to immediate postoperative complications or later in life due to pneumonia 1 5 12 13 19 20. Given this data, about 18% of the total cases had good outcomes that we know of.…”

Chiari III Malformation on Prenatal and Postnatal Imaging Complicated by Syndrome of Inappropriate Secretion of Anti-diuretic Hormone (SIADH) and Serratia marcescens Meningitis

“…Hydrocephalus is an additional feature to be aware of, present in 22% of cases [5]. MR venography (MRV) can also be useful for the preoperative delineation of the venous sinus anatomy surrounding the meningocele/myelomeningocele, as duplication of the superior sagittal sinus has been reported in these patients [10][11][12][13]. Additionally, dural sinuses may herniate along with cerebellar/brainstem tissue, which can be seen in up to 50% of cases [14].…”

Developmental and surgical anatomy of pathologies of the craniovertebral junction: a much-needed problematization of efficacy and long-term outcomes

“…Type 1 1 per 1280 live births (Capra et al, 2019) Type 2 1 per 1000 live births (Kuhn and Emmady, 2022) Type 3 51 cases reported (Elbaroody et al, 2021) Type 4 no data available Wallenberg syndrome 60 000 cases a year only in the United States (Venti, 2012) Syringomyelia 8.4 per 100000 live births (Sharma et al, 2006) Wallenberg Syndrome (WS) otherwise known as the lateral medullary syndrome was first mentioned in 1808 by Gaspard Vieusseux (1746Vieusseux ( -1814, with a more precise description of WS being presented by the German neurologist Adolf Wallenberg (1862Wallenberg ( -1949 in 1895 (Wallenberg, 1895). Vieusseux described WS as an occlusion of the vertebral artery or the posterior inferior cerebellar artery (PICA) followed by infarction of the lateral medulla oblongata (Lui et al, 2022).…”
