"While this classical definition of DWM remains true and is well established, borderline cases that don't fully meet these criteria have led to a confusing array of terminology in the literature, including Dandy-Walker variant, spectrum, complex and continuum."
"Note that this modernised definition of DWM does not mandate the presence of posterior fossa enlargement or torcular-lambdoid inversion to make the diagnosis. The size of the posterior fossa has been shown to be an inaccurate discriminator between DWM and its mimics in both the pre- and post-natal setting, as has the location of the torcula prenatally 2."

"The condition now known as Dandy-Walker malformation was first described by English surgeon John Bland-Sutton (1855-1936) in 1887 14. It was later characterised by American neurosurgeon Walter Edward Dandy (1886-1946) and paediatrician Kenneth Blackfan (1883–1941) in 1914 5 and was further described in detail by another American neurosurgeon Arthur Earl Walker (1907-1995) in 1942 6. The condition was first referred to as 'The Dandy-Walker Syndrome' by German psychiatrist Clemens Ernst Benda (1898-1975) in 1954 15."
