The lateral apertures (of Luschka) (also known as the foramina of Luschka) are two of the foramina in the ventricular system and link the fourth ventricle to the cerebellopontine cistern. Together with the median aperture (of Magendie) they comprise two of the three sites that CSF can leave the fourth ventricle and enter the subarachnoid space. The lateral aperture of the fourth ventricle or foramen of Luschka (after anatomist Hubert von Luschka) [1] is an opening at the lateral extremity of either lateral recess of the fourth ventricle opening anteriorly [2] into (sources differ) the pontine cistern [2] / lateral cerebellomedullary cistern [3] at cerebellopontine angle.

Microsurgical anatomy of the foramen of Luschka in the cerebellopontine angle, and its vascular
The uncovertebral joints, also known as the joints of Luschka or neurocentral joints, are the four pairs of plane synovial joints between the vertebrae C3-C7. They are found lateral and anterior to the intervertebral foramina, on each side of the relevant intervertebral discs. The foramina of Luschka (FOL) are counted as a considerable microsurgical corridor to the floor of the fourth ventricle. Understanding the patency of FOL can potentially improve tetraventricular microsurgical and neuroendoscopic approaches. The foramina of Luschka are of importance clinically as their blockage can disrupt the flow of cerebrospinal fluid leading to the development of hydrocephalus. These apertures were first described by the German anatomist Hubert von Luschka in the nineteenth century. These foramina are thought to emerge at around the 26th week of development.

Foramen Luschka
The foramen of Luschka is a natural aperture between the fourth ventricle and the subarachnoid space at the cerebellopontine angle (CPA). The microsurgical anatomy of the foramen and the related neurovascular structures is well described in the literature. 1, 2,. The son of a forester, Hubert Luschka was born on July 27, 1820 in Konstanz in the southwest corner of Germany. Interestingly, his hometown was the location of the Council of Konstanz, which condemned Bohemian reformer, Jan Hus, to death in 1415 for his criticism of the Catholic church. 1 Luschka was the eighth of 12 sons. Background: The German Anatomist Hubert Von Luschka first described the foramina of Luschka (FOL) in 1855 as lateral holes in the fourth ventricle. By his discovery, he refuted previous beliefs about the lateral recess as blind ends of the fourth ventricle, proving the continuity of the ventricular system with the central canal of the spinal cord. The CSF finally leaves the fourth ventricle through the foramen of Magendie and the foramina of Luschka to reach the subarachnoid space surrounding the brain. Each lateral ventricle lies within a cerebral hemisphere.
VENTRICLES AND THE CEREBROSPINAL FLUID Neupsy Key
The fluid (cerebrospinal fluid) is produced in the ventricular system of the brain. There are four such hollow spaces in the brain that house cerebrospinal fluid (CSF): two lateral ventricles, a third ventricle and a fourth ventricle. This article will look at the structure of this system and how it helps the brain. Contents Choroid plexus Hydrocephalus can be classified as either "obstructive and non-obstructive" or "non-communicating and communicating" based on the presence of a flow circulation abnormality inside or outside the ventricular system.

lateral foramina of Luschka: Also known as the lateral aperture, an opening in each lateral extremity of the fourth ventricle of the human brain that provides a conduit for cerebrospinal fluid to flow from the brain's ventricular system into the subarachnoid space. EXAMPLES. Gender: Female. ct. Bilateral linear calcification in the 4th ventricle extending laterally though the foramina of Luschka, represent choroid plexus calcification. This can mimic interventricular hemorrhage. Marked choroid plexus calcification in the lateral ventricles. No acute infarct. Old bilateral insular ischemic changes.
