====== Foramen of Luschka ======

{{::foramenluschka.jpg|}}

The [[lateral aperture]] is a paired structure.

It is an opening in each lateral extremity of the lateral recess of the [[fourth ventricle]] of the human brain, which also has a single [[median aperture]]. The two lateral apertures provide a conduit for cerebrospinal fluid to flow from the brain's ventricular system into the subarachnoid space; specifically into the cerebellopontine angle. The structure is also called the lateral aperture of the fourth ventricle or the foramen of Luschka after anatomist Hubert von Luschka.
----
Lesions lateral to the lower [[brainstem]] in an area extending from the foraminae of Luschka to the [[foramen magnum]] are rare and include different pathologies. There is no consensus on an ideal surgical approach.
