The fourth ventricle is the lower blue mass. The little points sticking out on the left and right are the two parts of the lateral recess. The lateral recess or lateral recess of fourth ventricle, is a projection of the fourth ventricle which extends to the lateral border of the brainstem at the pontomedullary junction.
Dandy–Walker malformation (DWM), also known as Dandy–Walker syndrome (DWS), is a rare congenital brain malformation in which the part joining the two hemispheres of the cerebellum (the cerebellar vermis) does not fully form, and the fourth ventricle and space behind the cerebellum (the posterior fossa) are enlarged with cerebrospinal fluid.
The median aperture (median aperture of fourth ventricle or foramen of Magendie) is an opening at the caudal portion of the roof of the fourth ventricle. [1] It allows the flow of cerebrospinal fluid (CSF) from the fourth ventricle into the cisterna magna. [2] [3] The other openings of the fourth ventricle are the lateral apertures - one on ...
The lateral aperture, lateral aperture of 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 at cerebellopontine angle.

During fetal development, some choroid plexus cysts may form. These fluid-filled cysts can be detected by a detailed second trimester ultrasound. The finding is relatively common, with a prevalence of ~1%. Choroid plexus cysts are usually an isolated finding. [18] The cysts typically disappear later during pregnancy, and are usually harmless.
The ICD-10 Procedure Coding System (ICD-10-PCS) is a US system of medical classification used for procedural coding.The Centers for Medicare and Medicaid Services, the agency responsible for maintaining the inpatient procedure code set in the U.S., contracted with 3M Health Information Systems in 1995 to design and then develop a procedure classification system to replace Volume 3 of ICD-9-CM.
Axial MR/CT show a triangular-shaped cerebrospinal fluid (CSF) space between the lateral ventricles. On sagittal images, CVI can appear as a slit-like, linear-to-round/ovoid CSF collection below the fornices, and above the 3rd ventricle. There are usually no associated abnormalities, although larger lesions may cause an obstructive ...
Obstetric ultrasonography, or prenatal ultrasound, is the use of medical ultrasonography in pregnancy, in which sound waves are used to create real-time visual images of the developing embryo or fetus in the uterus (womb).
