“…The torcular Herophili cannot be imaged clearly with sonography due to acoustic shadowing from the skull bones and we inferred its position by observing the angulation of the tentorium (Figure 2). To evaluate the cerebellar vermis we used a combination of qualitative findings (visualization of fastigium and fissures)3, 6, 13, 14 as well as biometry8, 10. Nevertheless, frequently we were uncertain about vermian integrity, particularly in the context of Dandy–Walker malformation, because of upward compression by the posterior fossa cyst (Figure 3).…”
