Serpiginous choroiditis, also known as geographic helicoid peripapillary choroidopathy (GHPC), is a rare, chronic, progressive, and recurrent bilateral inflammatory disease involving the retinal pigment epithelium (RPE), the choriocapillaries, and the choroid. [1] It affects adult men and women equally in the second to seventh decades of life. [2]
Chorioretinitis is an inflammation of the choroid (thin pigmented vascular coat of the eye) and retina of the eye. It is a form of posterior uveitis. Inflammation of these layers can lead to vision-threatening complications. If only the choroid is inflamed, not the retina, the condition is termed choroiditis. [1]
The choroid plexus, or plica choroidea, is a plexus of cells that arises from the tela choroidea in each of the ventricles of the brain. [1] Regions of the choroid plexus produce and secrete most of the cerebrospinal fluid (CSF) of the central nervous system. [2] [3] The choroid plexus consists of modified ependymal cells surrounding a core of ...

A choroid plexus carcinoma (WHO grade III) is a type of choroid plexus tumor [1] that affects the choroid plexus of the brain. It is considered the worst of the three grades of chord plexus tumors, having a much poorer prognosis than choroid atypical plexus papilloma (WHO grade II) and choroid plexus papilloma (WHO grade I). [2]
In children and adults, respectively, the lateral ventricle and the fourth ventricle are common locations, [8] [9] [10] About 5% of all choroid plexus tumors are located in the third ventricle. [11] Along with other unusual places such the cerebellopontine angle, the Luschka foramen, or brain parenchyma, the third ventricle is a rare location ...
Choroideremia (/ k ɒ ˌ r ɔɪ d ɪ ˈ r iː m i ə /; CHM) is a rare, X-linked recessive form of hereditary retinal degeneration that affects roughly 1 in 50,000 males. The disease causes a gradual loss of vision, starting with childhood night blindness, followed by peripheral vision loss and progressing to loss of central vision later in life.
The area of the brain most damaged in early Huntington's disease is the dorsal striatum made up of the caudate nucleus and the putamen. Initially, damage to the brain is regionally specific with the dorsal striatum in the subcortical basal ganglia being primarily affected, followed later by cortical involvement in all areas.
