Infobox disease Name Choroid plexus cyst Image Caption DiseasesDB ICD10 ICD10 G 93 0 g 90 ICD9 ICD9 348.0 ICDO OMIM MedlinePlus eMedicineSubj eMedicineTopic MeshID Choroid plexus cysts CPCs are cyst s that occur within choroid plexus of the brain. The brain contains pockets or spaces called ventricular system ventricles with a spongy layer of cells and blood vessels called the choroid plexus . This is in the middle of the fetal brain. The choroid plexus has the important function of producing a fluid called cerebrospinal fluid. The fluid produced by the cells of the choroid plexus fills the ventricles and then flows around the brain and the spinal cord to provide a cushion of fluid around these structures. CPCs can form within this structure and come from fluid trapped within this spongy layer of cells, much like a soap bubble or a blister. CPCs are often called soft signs or fetal ultrasound markers because some studies have found a weak association between CPCs and fetal chromosome abnormalities. It is believed that many adults have one or more tiny CPCs. ref name pmid15832013 cite journal author Jeon JH, Lee SW, Ko JK, et al. title Neuroendoscopic removal of large choroid plexus cyst a case report journal J.

The four primary nerve plexus nerve plexi are the cervical plexus , brachial plexus , lumbar plexus , and the sacral plexus . The choroid plexus is a part of central nervous system in the brain and it consist of capillaries, ventricles and ependymal cells .

- Choroid fissure
refimprove date March 2011 The choroid is the middle, vascular coat of the human eye eye which resides between the sclera and the retina . Early in development the choroid fissure is the slit observed between the two edges of the eye cup. During development it is through the choroid fissure that the retinal vessels enter the eye and neural components e.g. axon s and retinal ganglion exit the eye to form the optic nerve . The fissure is eventually sealed when the edges of the retina join together. Failure of this fissure to close results in coloboma iridis . ref cite book last Fix first James D. title High Yield Neuroanatomy year 2009 publisher Lippincott Williams & Wilkins pages 13 ref References reflist Category Eye anatomy med stub ... more details
